Rely on tested quality and order clutch heads directly online.

Reliable interface for air systems

The coupling head forms the elementary connection between the compressed air line and the vehicle or trailer system. It allows the air supply to be connected and disconnected quickly and tightly, while at the same time having to withstand high stresses, vibrations and weather conditions in order to prevent leaks and faults.

High-quality materials and sophisticated function

A good coupling head is corrosion-resistant, robustly manufactured and designed to ensure a secure seal every time it is engaged and disengaged. The sealing surface and contact mechanisms must also be precisely manufactured so that the air pressure is reliably transmitted with every connection.

Coupling head

What should you look out for when buying:

HEADING TYPE

The coupling head must exactly match the coupling standard used (e.g. thread size or quick coupling system).

OPERATING CONDITIONS

Make sure that the component is designed for the area of use of your vehicle – whether on the road, in cold weather or with frequent use.

MOUNTABILITY

Choose models that are easy to install and can be easily cleaned or maintained if necessary to ensure long-term reliability.

Expert Guide: Everything You Need to Know About the Clutch Head

The coupling head forms the connection between the towing vehicle’s compressed air line and the trailer or vehicle system. It enables quick, leak-free coupling and uncoupling of the air supply while reliably transmitting air pressure—the basis for the trailer brake’s operation.

The entire compressed air supply to the trailer passes through the coupler head. A leaky connection leads to a loss of pressure and can impair braking performance. Precisely machined sealing surfaces and contact mechanisms ensure that air pressure is reliably transmitted every time the trailer is coupled or uncoupled.

Typical signs include audible air escaping from the connection, delayed pressure buildup, a clutch that is stiff or does not close properly, and visible wear or damage to the seal and housing. Such defects should be repaired promptly.

It is crucial that the coupling head precisely matches the coupling standard being used (e.g., thread size or quick-connect system). Also make sure that the component is designed for your vehicle’s operating conditions—such as cold temperatures or frequent use—and that it is easy to install and maintain.
