Air pressure control is important for everyone

Air-Flexx valve extensions are suitable for semitrailer and trailer combinations, car transporters, motorhomes, waste disposal and municipal vehicles, tippers and vans. For passenger cars, it should be noted that metal valves must be installed in the tires.
The 75 and 85 millimeter versions are intended for front and single wheels with hubcaps
Models from 105 to 215 millimeters are used for inner dual wheels. All valve extensions in these categories can be used without additional holders or retaining brackets.
Larger calibres between 315 and 1000 millimetres in length are the perfect solution for trucks and coaches to maintain the air pressure in the tires even when the valves of spare wheels are difficult to access
Front and single wheels with hubcaps: 75 mm, 85 mm and 105 mm
Inner dual wheels: 105 mm, 145 mm, 170 mm, 185 mm, 215 mm
Spare wheels 315 mm, 415 mm, 1000 mm

"Safety is our job"

Air-Flexx valve extensions are designed for maximum breaking strength

Underinflated tires are a safety risk
Valve extensions have to withstand high loads in everyday use
Air-Flexx valve extensions are a benefit for vehicle safety

Interview between Jo Geiger and Tobias Glauch on the subject of increased safety for trucks through the use of break-proof and pressureless valve extensions.

Air-Flexx has been on the market since 1999. They are a supplier to renowned commercial vehicle manufacturers and the German Armed Forces. What can Air-Flexx do that others can't?

Glauch: Air-Flexx valve extensions are designed for maximum breaking strength and function absolutely pressureless. What makes Air-Flexx special

is the combination of these two product properties. This is unique on the market in this form. You can choose between flexible rubber extensions that

are pressurized with the tire pressure. Or rigid valve extensions, which then work without pressure.

What role do valve extensions play in vehicle safety?

Glauch: A tire with too little air is always a safety risk, especially with inner dual tires. As a result, the outer tire is overloaded and a blowout is always possible. On the drive axle of 4x2 trucks, this can lead to serious accidents. An intact extension is therefore a benefit for greater vehicle safety. This is

why these components are now a separate test point in the safety test.

What advantage do Air-Flexx valve extensions offer?

Glauch: In practice, it is often the case that a valve extension does not pass freely through the slanted rim hole of the outer wheel, but is in contact with the edges. This means that the extensions are constantly under tension. Stress factors such as braking heat and cold, as well as mechanical impact from stones, snow and ice, also affect the extensions. In this respect, Air-Flexx offers a tangible safety benefit thanks to its breaking strength, flexibility and robustness.

What handicaps do you see with conventional extensions?

Glauch: Rigid valve extensions are usually made of plastic or brass. Both types can break easily. In this case, the air remains in the tire. However, you

can then no longer check the air pressure or top up the air. A flexible extension is usually made of rubber but does not have a valve pin. When you

screw the component onto the tire valve, the valve insert in the tire valve is opened and the air flows from the tire into the extension. The rubber

extension is therefore 100 percent under full air pressure when driving. If the extension is damaged, air loss is therefore inevitable.

How break-proof are Air-Flexx valve extensions?

Glauch: You can probably break the extension with a sledgehammer. Otherwise you have to make a lot of effort. We have tested the system in extensive practical trials with heavy trucks on construction sites and in quarries. Stones, metal parts and even sharp objects were no match for the extensions.

With air-flexx® valve extensions: always on the safe side

Caring for twin tires brings with it special challenges. A regular air pressure test on inner twin tires often cannot be carried out because plastic or tube tire valve extensions have either broken off or are missing. This is why the air pressure on inner twin tires is often too low. The consequences are greater tire wear and a greater risk of accidents. Dekra presented the dangers in an extensive study.

Air pressure control on commercial vehicle tires is often inadequate. DEKRA carried out a series of tests.

Viersen. The black tire fragments that are left behind on German freeways - often by commercial vehicles - are frequently the result of mechanical tire damage, but very often also due to insufficient internal pressure in conjunction with an overload of the commercial vehicle tires. Apart from the fact that such damage is annoying and expensive for the owner, destruction of the tire while driving also leads to a considerable impairment of road safety.

Air pressure control on commercial vehicle tires is often inadequate (2) DEKRA investigation led to surprising results.

Viersen. Who doesn't know the black tire fragments - often left by commercial vehicles - on German motorways. Tread damage caused by foreign bodies, overload and often insufficient internal pressure in commercial vehicle tires can lead to such damage. This damage is not only annoying and expensive for the commercial vehicle owner, but is also quite dangerous for the affected commercial vehicle itself and for other road traffic.
