UNO-MATIC trailer part with one-way valve

Uno-Matic is the replacement for the older version, Duo-Matic.

The difference between Unomatic and Duomatic includes enhanced safety, longer lifespan, and improved ergonomics.

The main function of the trailer part is to connect the trailer's air brake system with the vehicle's braking equipment.

This can be between a lorry and trailer or a tractor and semi-trailer.

It can also be used to connect other components requiring air pressure, for example, between a lorry and hook-lift frame for those with an air outlet.

For this purpose, a separate connector is used, not the brake line usually associated with trailers.

The housing is made of hard-anodized Aluminium to provide the best protection against corrosion and wear.

This coupling features a one-way valve.
