 ALLIGATOR delivers over 200 million safety parts to our customers every year. Functioning quality management is just as much a prerequisite for this as long-term cooperation and partnership with our customers and suppliers. Valves and tire pressure monitoring systems (TPMS) are safety parts. For this reason, both dimensions and functions are checked fully automatically during production and assembly.

ALLIGATOR | EHA

TIRE INVENTORY AND ACCESSORIES | EHA

In 1931, 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 1939 the company decides to move its headquarters to Mühlheim.

In 1956, 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.

1975: The export share of the EHA valve factory is 70% in 60 countries.

1998: Takeover of EHA Ventilfabrik W. Fritz GmbH & Co. KG by ALLIGATOR.

2003: Merger of EHA Ventilfabrik with ALLIGATOR Ventilfabrik GmbH.

OUR PRODUCTS

ALLIGATOR VALVES

In addition to the classic valves for cars, trucks and motorcycles, ALLIGATOR product range also includes special valves for tractors or earth-moving machines. An ongoing exchange of ideas and experience between ALLIGATOR and its customers has created a partnership based on trust and innovation.

TPMS valves for all vehicles from cars to trucks

As the leading manufacturer of valves, ALLIGATOR always sets out to meet the ever-increasing demands on tire valves with high levels of quality and safety. The tire pressure monitoring system that is built into ALLIGATOR TPMS valves: through tire pressure monitoring and the direct indication of any pressure loss, they ensure driver’s safety. If the tire pressure is incorrect, which often stays undetected without a tire pressure monitoring system, the braking distance is increased and the cornering ability is impaired.

Advice on choosing and installing tire valves:

For higher pressures & vehicle speeds, a metal clamp-in valve is recommended. Colder climates, use the snap-in rubber stem.

CAR VALVES

ALLIGATOR rubber and metal car valves offer the optimal solution for every requirement.

SNAP-IN RUBBER VALVES

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.

CLAMP-IN METAL VALVES

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.

TRUCK VALVES

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!


LIGHT TRUCK VALVES

Light trucks and mobile homes are subjected to enormous stress in daily use. The tire valves must withstand high tire inflation pressures, average speeds and temperatures while sealing reliably.

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.

CVVeasy: combines the benefits of rubber and metal valves

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.

AGRICULTURAL VALVES

ALLIGATOR's product range includes air and water valves especially for the agricultural sector. For safe and reliable filling of tractor tires with water.

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.

TRACTOR VALVES

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.

EARTHMOVER VALVES

Valves for construction machines or earthmovers are used for earth moving machines, heavy-duty trucks, high-capacity tippers, dumpers, loading, conveying and levelling equipment and cranes.

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.

EM - RIGID VALVE EXTENSIONS

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.

EM - FLEXIBLE VALVE EXTENSIONS

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.

ALLIGATOR TPMS

The ALLIGATOR product range covers all requirements in the field of TPMS.
From sensors to the appropriate programming device, everything is provided. Our sens.it® product line offers the right solution for every area of application: whether workshop operator or complete wheel manufacturer.




ALLIGATOR TPMS Sensor - Sens.it RS+

With the freely programmable universal sensors from ALLIGATOR sens.it, your workshop is equipped for every situation: The universal sensors are not pre-programmed, so they can be individually adapted to the respective vehicle model. This reduces the variety of sensors required, which a workshop must have in stock, and simplifies the work process. Although vehicle-specific programming does take some time, universal sensors can be updated again and again and therefore do not become obsolete.

All the advantages of the ALLIGATOR sens.it® RS universal sensors at a glance:

  • Very high vehicle coverage
  • Correspond to OE sensors in quality and functionality
  • Perfect sensor fit due to flexible adjustment
  • Number of stored parts and associated costs can be reduced
  • Risk of installing the wrong sensor is reduced
  • Fast and easy workflow
  • Loss of sales due to non-stocked built-in parts is avoided
  • Sensors can be programmed both before and after mounting the tires

ALLIGATOR PROGRAMMING DEVICES

Basically, two variants are available for the programming of sens.it® sensors:

PT1 Programming Pad
AVT41 TPMS tool

The ALLIGATOR Programming Pad PT1 has been specially developed to program sens.it® sensors exclusively. It is not possible to read out already programmed sensors. The device is therefore an ideal and cost-effective addition to wireless TPMS handheld devices.

The ALLIGATOR AVT41 TPMS tool is an ideal supplement to the ALLIGATOR programming device PT1. It supports the work flow in the workshop, for example, by being able to check the function, sensor ID, tire pressure and temperature of all TPMS sensors installed in the vehicle when the vehicle is accepted.

ALLIGATOR TPMS VALVES & SERVICE KITS

TIRE valves have to withstand heavy loads during their service life and are subject to many different external influences. This can cause a loss of pressure and therefore be a safety risk. That is why valves should be replaced at each tire change.

The tire pressure monitoring service kits from ALLIGATOR contain all the components required for professional servicing  tire valves with a TPMS sensor. The service kits are assigned to the specific vehicle on the basis of the characteristics "Manufacturer", "Model" and "Year".

With every tire change, all relevant components of a TPMS valve should be replaced as a matter of principle, because

  • Valve cap
  • Valve core
  • Valve nut
  • Valve grommet

are subject to particular aging and corrosion influences. For this very reason, the replacement of these components during tire service is recommended.

ALLIGATOR TPMS TOOL

With the TPMS tool from ALLIGATOR, sensors and valves can be professionally attached to any rim.

The one-handed operation of most tools enables quick and easy assembly without wasting time. Thanks to sophisticated technology, bit changes are also lightning fast.

In addition to individual tools, such as torque wrenches, you will find fully equipped tool bags and cases for the installation of TPMS. These are suitable for sens.it & OE TPMS sensors.

The ALLIGATOR sens.it starter kits offer an easy and inexpensive introduction to TPMS service. You will find everything you need in one box.

ALLIGATOR TOOLS AND ACCESSORIES

We always have our customers needs in mind. To ensure professional, quick and easy installation or repair of valves and TPMS solutions, the ALLIGATOR product range also offers the right tools and accessories.

VALVE CAPS

The ALLIGATOR product range also offers a wide variety of valve caps. From plastic caps to check valve caps - we have what you need.

In addition to metal valve caps and colorful plastic caps (with and without seals), ALLIGATOR has many other variants of valve caps in its range - specially tailored to your needs.

VALVE INSERTS

Every tire valve has a valve insert - also called a valve inserts. Valve inserts protect against dirt, wetness and gradual pressure loss and are therefore of great importance for the tightness of a valve. As a wearing part, the valve insert must be checked and replaced at regular intervals. ALLIGATOR offers replacement valve inserts for every application - and at the highest quality!

Whether long or short, for car or truck - at ALLIGATOR you will find the right spare part! All of our valve inserts are characterized by particularly high tightness. In addition, the products impress with their easy handling and good workmanship.

Which valve insert, short or long, is the right one for your application depends on the rim design and the valve type. Under no circumstances should the valve protrude beyond the rim flange.

Many of our valve inserts are nickel-plated. Nickel-plated valve inserts are of higher quality and provide even better protection against corrosion. To prevent contact corrosion, a nickel-plated valve insert is therefore used with many ALLIGATOR valves.


VALVE TOOLS

The ALLIGATOR valve range is complemented by suitable valve tools. Special and high-quality tools are essential for the professional assembly and disassembly of valves.

Our practical ALLIGATOR valve tools facilitate and speed up the professional assembly and disassembly of valves. From valve pullers to valve wrenches and pocket air pressure testers. ALLIGATOR offers you the ideal support for your daily work.

The ALLIGATOR range of valve tools includes: Valve retractor lever, Valve wrench, Thread cutter, Valve catcher and much more.
