The high-quality rubber valves for cars by ALLIGATOR fit perfectly into the rim. Their advantage is that the elastic valve stem allows the tire valve to be adjusted to suit the particular angle when checking the air pressure – this makes the work in the workshop easier. ALLIGATOR snap-in rubber valves also meet the highest standards – they have been tested and manufactured in accordance with OEM requirements for car valves. These are significantly more stringent than ETRTO and DIN standards. Since valves should also be replaced when changing tires or wheels, ALLIGATOR car valves are also marked with the year of manufacture. Because of the natural aging process of rubber valves, you can therefore be sure that the car valves are suitable for use and meet your requirements when changing your wheels. It is also possible for tire valves to be individually marked. Snap-in valves can be used on a wide range of vehicle types and they are also suitable for all steel and aluminum rims at speeds of up to 210 km/h. For speeds above 210 km/h, we recommend using either metal valves (clamp-in) or valve supports to limit the valve deflection to a maximum angle of 25° when travelling at such high speeds.
With competitive price and timely delivery, foxwell sincerely hope to be your supplier and partner.
ALLIGATOR car valves made out of metal are manufactured based on OEM requirements and are therefore the perfect choice when only the highest quality is needed. These metal valves are optimised for heavy duty wheels of fast cars and transporters that travel at speeds over 210 km/h. At high speeds the centrifugal force makes traditional rubber valves bend out of shape: this doesn’t happen to the clamp in metal valves of ALLIGATOR. The adherence of ALLIGATOR car valves to strict quality standards ensures the safety not only of the tires, but also of the driving. In addition to universal metal valves, ALLIGATOR also offers metal valves with ASC seals. The advanced seal concept used in the ASC-HT metal valves ensures that the tightening forces are introduced directly into the metal of the rim. This allows the seal to do its job without being affected by external forces.
At ALLIGATOR, the quality of our products is extremely important to us. As the leading manufacturer in the valve sector, we have made it our business not only to meet our customers' requirements but also to inspire them: together we meet the daily growing challenges with constantly new solutions and ideas.
Truck valves have to withstand heavy loads during their service life and are subject to many external influences. Any resulting loss of tire pressure presents a significant safety risk for all road users. A drop in pressure will result in longer braking distances and it is also not uncommon for control loss of the vehicle. Our truck valves are finished with a nickel coating to protect the surface from wear, corrosion and external damage.
ALLIGATOR truck valves for commercial vehicles are nickel-plated to protect them against corrosion. When combined with the V2B double seal valve cap, these truck valves are the optimal solution for haulage contractors, bus companies and transport associations.
V2B GATOR CAP
With up to 18 wheels per vehicle, valves that are difficult to access and heavy dirt, checking the air pressure of commercial vehicles is not at all easy. The ALLIGATOR V2B check valve cap provides a remedy. It does not need to be removed for filling or checking the air pressure.
Save time - according to information from the tire manufacturer Bridgestone, a study in the USA showed that the average time required for checking tire pressure on a vehicle combination can be reduced from approx. 20 minutes to 6–7 minutes by using ALLIGATOR check valve caps V2B. The additional costs of the valve cap are therefore amortized after only two pressure checks. ⇾ 13 minutes time saving at least 1x a month
Save money:
An underinflation of 1 bar increases fuel consumption by about 1.2% - and 30% underinflation halves the life of the tire. A good valve cap can prevent creeping air loss and thus helps to save money!
ALLIGATOR offers the right valves, especially for these highly stressed wheels. CVVeasy, for example, combines the pressure load capacity of a metal valve with the ease of installation of a snap-in rubber valve. The thrust washer thus holds the valve securely in the wheel even under high pressure loads.
The patented design of the CVVeasy tire valve combines the pressure load capacity of a metal valve with the easy installation of a snap-in rubber valve. The optimized seal contour and highly flexible sealing lip on the car valve ensure optimal tightness in the rim. The pressure disc holds the tire valve securely in the wheel, even under high operating pressures.
To remove the car valve, simply cut through and remove the pressure disc at the predefined breaking point using pliers or a screwdriver. The car valve can then be pulled out of the valve hole quite easily without needing any special tools. As well as saving time, this design also virtually eliminates the risk of damaging the rim with removal tools.
These valves are suitable mainly for transporters and motorhomes which are exposed to considerable loads during daily use.
The wide passage allows the large tires to be filled with water in a short time, after removing the valve insert, to improve the tractive power of the tractor. Despite filling with water, the usual air filling of the tires cannot be dispensed with. The tractor tires can be filled with water and emptied completely using the appropriate water-filling fittings.
ALLIGATOR offers air and water valves for agricultural use for filling tractor tires with water reliably and safely. Once the valve insert has been removed, the wide aperture enables large tires to be filled with water quickly to improve the traction of the tractor. Of course, filling the tires with water does not mean that they don't need to be filled with air as standard. When filling with water and emptying the tractor tires completely, appropriate water-filling fittings are used. In our product range we have a comprehensive selection of straight and curved rim valves, snap-in valves, tractor valves, tube valves and tube valves with a rubber base. At ALLIGATOR, you will find all the high-quality products you need for your tractor wheels.
Oversized and large-volume tires are mainly equipped with so-called earthmover valves (large bore valves). These valves have particularly wide bore cross-sections that allow the required amounts of air to flow through quickly. The most common valve configuration for oversized tires is the combination of an EM rim base with the corresponding EM upper. The matching EM top can be easily and quickly fitted into the EM rim base.
Rigid valve extensions are always used if the wheel conditions permit a straight extension of the valve. The valve insert must not be removed from the EM valve. Rigid EM valve extensions are fitted with an extension insert which has no sealed function, but merely opens the insert located in the valve during tire inflation or pressure testing.
Flexible valve extensions are mounted when the straight extension of the valve mouth by a rigid valve extension is not possible. These valve inserts are provided with sealed original EM valve extensions TR C 2 (in contrast to rigid EM valve extensions with extension inserts without sealing effect). Nevertheless, the valve insert of the valve should not be removed so that the tire pressure does not escape when the extension is detached from the tire valve. The valve connection fitting of the extension is designed so that the EM valve insert TR 2 is open when the extension is permanently screwed on.
In , the "Erste Hanauer Präzisions-Schrauben- und Walzendreherei" is founded in Hanau. An idea that had already existed for some time, the production of tire valves, is put into practice. This lays the foundation for the production of tire valves.
In the company decides to move its headquarters to Mühlheim.
In , the first snap-in valves are developed and produced in the EHA valve factory. Technicians and rubber specialists at EHA develop a rubberizing process that is unique at the time. The brass parts are rubberized without using a primer. The rubber compound used and the newly developed galvanic (chemical) pre-treatment process provide excellent conditions for achieving a good rubber-metal bond.
: The export share of the EHA valve factory is 70% in 60 countries.

: Merger of EHA Ventilfabrik with ALLIGATOR Ventilfabrik GmbH.
An auto relearn procedure is when a vehicle has the ability to learn single or multiple TPMS sensor IDs without the need of performing the relearn procedure with a TPMS tool. Furthermore, a technician can adjust the inflation pressure, rotate or replace sensors and the TPMS system will reset itself after the vehicle has been driven for a period of time. However, before servicing the tires/wheels, it is always recommended to use a TPMS tool to trigger each of the vehicle’s sensors to make sure they are working properly.
For example, a Dodge Charger requires the following auto relearn procedure:
Image of VT56 screen displaying auto relearn procedure for Dodge Charger
Replace an old sensor by creating a new sensor ID using a blank aftermarket programmable sensor. Before servicing tires, trigger the vehicle’s sensors by Make, Model, Year selection or VIN scan. (VIN scan option available in North America only.) Triggering the vehicle’s sensors will allow you to identify damaged or defective sensors. If your tool fails to display the sensor information after trying to trigger the sensor, you will need to create a new sensor by selecting the vehicle’s Make, Model, Year or by sensor model.
Watch the video below to learn how to program an aftermarket TPMS sensor with the VT56. The same instructions apply for all other TPMS tools that are able to program sensors.
There are two ways to program a blank sensor with the ATEQ VT56.
Option 1, select by sensor manufacturer.
– From the main menu, select program then select the programmable sensor model you are working with. (Note, ATEQ TPMS tools program ALL major aftermarket programmable sensor brands.)
– Next, select the vehicle’s Make, Model, Year.
– Select CREATE, press OK to create new sensor information.
– Position the sensor in front of the tool’s antenna.
– The sensor has been successfully programmed.
Option 2, select by vehicle Make, Model, Year.
– From the main menu, select program, then select the vehicle’s Make, Model, Year.
– Next, select the programmable sensor model you are working with. (Note, ATEQ TPMS tools program ALL major aftermarket programmable sensor brands.)
– Select CREATE, press OK to create new sensor information.
– Position the sensor in front of the tool’s antenna.
– The sensor has been successfully programmed.
An OBDII relearn procedure requires a TPMS diagnostic tool to transfer new sensor IDs directly to the vehicle’s ECU. The user will need to trigger each TPMS sensor, connect to the vehicle’s OBD port, then follow the step-by-step instructions on the tool. The new TPMS sensor IDs are then transferred to the vehicle. Most Asian and specialty European vehicles require OBD relearn.
For example, a Toyota Camry requires the following OBDII relearn procedure:

Manual and stationary relearn systems can sometimes take several steps to relearn the TPMS system. TPMS diagnostic tools have the step-by-step instructions for auto, stationary and OBD relearn, however, the steps involved can be long and complicated. OBD relearn procedures are becoming standard in a shop environment for many reasons. First and foremost, it is the easier to work with since the same procedure can be performed no matter what the vehicle type is. Secondly, OBD relearn saves time and confusion for the technician since there are less steps to perform. According to amra.org, 62% of vehicles require a TPMS diagnostic tool and 27% require OBD functionality. It is important to have a reliable TPMS diagnostic tool with excellent OBD coverage to keep up with the growing industry of TPMS.
Did you know? ATEQ has the largest OBD coverage (86% and growing) to help shop owners save time and money!

Vehicles with direct-type TPMS systems are equipped with TPMS sensors. If a TPMS sensor is not working, it must be replaced before a relearn procedure can be performed. The damaged TPMS sensor can be replaced by an OE sensor or an aftermarket sensor.
There are different types of aftermarket TPMS sensors including universal, configurable and programmable sensors. OE sensors, universal and configurable sensors have new sensor ID’s already encoded within the sensor and need to be activated by using a TPMS diagnostic tool. Programmable TPMS sensors require a TPMS diagnostic tool to create new sensor ID’s or transfer sensor ID’s from the old sensor.
For multi-brand repair shops, a mix of universal sensors and OE sensors is often required. Our tools support the largest aftermarket sensor list on the market including, Alligator sens.it, BWD Standard OE and Standard QWIK, Continental REDI-Sensor, Dorman Direct Fit, Hamaton U-Pro, HUF IntelliSens, MOBILETRON, NAPA QWIK and OE Design, Orange Simple Sensor, Schrader EZ-sensor, SMP Standard OE and Standard QWIK and STEELMAN Select.
Some important features of the ATEQ VT56 and VT36 when working with TPMS sensors include:
A stationary relearn procedure allows new TPMS sensor IDs to be transferred to the vehicle’s ECU without driving a vehicle. This type of relearn procedure requires a TPMS activation tool to trigger the sensors when the vehicle is in learn mode either by using a TPMS diagnostic tool or a diagnostic scan tool. The vehicle then uses a radio frequency (RF) signal to communicate with the vehicle’s ECU to establish which sensor is in which specific location.
For example, a Ford Escape (with standard ignition) requires the following stationary relearn procedure:
Image of VT56 screen displaying auto relearn procedure for Ford Escape (with standard ignition)
When service has been performed to the vehicle’s direct TPMS system, such as air pressure adjustment, tire rotation or replacement of sensors, vehicles require a TPMS system relearn to be performed. A relearn allows the vehicle’s ECU to see the ID’s of each sensor in each wheel. Completing the relearn procedure clears TPMS diagnostic fault codes and allows the vehicle’s TPMS system to function properly.
Relearn procedures vary by manufacturer, so a technician must know which proper relearn procedure is necessary to put the vehicle in learn mode. Although relearn procedures differ from manufacturer to manufacturer, the three types of relearn procedures for direct TPMS systems are auto relearn, stationary and OBD. Furthermore, some vehicles may use a combination of two or more relearn types. Indirect TPMS systems use an initialization procedure which may require a TPMS tool to figure out the steps involved to reset the system.
The chart below represents the three types of TPMS relearn procedures within the market of Asian, Domestic and European vehicles equipped with direct TPMS systems.

The light will illuminate when a tire is low, and should eventually go out after a tire has been inflated to its recommended pressure according to the vehicle’s door placard. After starting a vehicle, a TPMS icon will turn on for a few seconds, however, if it stays on, it indicates that one or more of the tires on the vehicle is at least 25% below the recommended pressure. If the light flashes for approximately one to two minutes, it indicates there is a malfunction in the TPMS system.
There are numerous situations that can cause a TPMS warning light to come on or flash. Some TPMS problems include:
A TPMS reset tool can be used to reset or reprogram the OEM or Aftermarket TPMS sensor to the vehicle’s ECU whenever tires are replaced or changed from summer to winter tires, tire is replaced, tire rotation, etc.

A TPMS decoding tool can trigger or activate sensors, receive TPMS sensor information and send the TPMS sensor information to the vehicle’s ECU. The TPMS sensor information received by the TPMS decoding tool includes the pressure within the tire, the temperature of the TPMS sensor, the wheel rotating speed, the TPMS sensor unique ID, the battery status of the TPMS sensor, and more.

There is new firmware available for the OBDII module, and the device is attempting to communicate with the vehicle and complete a firmware update at the same time. Simply power the tool off and then on again. Once the main menu is displayed, connect the OBDII module only to the device; leaving the other end disconnected from any vehicle. The OBDII module will be detected almost immediately by the tool and the firmware, and the update will begin. The update takes less than 60 seconds to complete. Once completed, disconnect the OBDII module and power the device off. The update is now complete.
The tire pressure monitoring system (TPMS) primary function is to make the driver aware of the state of tire pressure within the wheels. Under normal system operations, the TPMS system will alert the driver when one or more affected tires PSI reading falls below 25% of the placard. When the tire sensor indicates “low tire pressure”, it sends a radio frequency (RF) signal of 315 or 433 MHz to the ECU on the vehicle that determines if the pressure is below the threshold, which then will indicate a TPMS symbol or position-specific display, depending on the vehicle.
In , after Firestone recalled more than 6.5 million vehicles due to tread separation, the NHTSA (National Highway Traffic Safety Administration) issued the first version of the TREAD Act which required Tire Pressure Warning Systems to be implemented on all vehicles sold in the United States by the year including all passenger vehicles and light trucks with GVWR of 10,000 lbs. and less.
Advantages of a TPMS system:
A TPMS equipped tire can display the TPMS sensor internal pressure and warns drivers when it reaches a low level by displaying a TPMS warning light.
