About Air Pressure Couplings

We offer a wide range of competitively priced high quality air hose couplings (claw couplings) as well as air hoses and air hose restraints (known as whipchecks). Our range also includes many products from the Ludecke range. The three main categories are the European standard (BSP Threaded) ‘Q’ type claw coupling, which is available in either standard or as a ‘Safeloc’ (safety version with pins), or we also supply the American standard (NPT threaded) ‘Universal’ claw type coupling (also known as a crows foot fitting).

A brief product overview is available below or in the product sections. If you require any further assistance, please call the team on 01235 512500.

These claw type air hose couplings are specifically designed for use with compressed air applications. They can be used to connect airlines and hoses with air powered tools and other industrial equipment. Connected by simply twisting the identical halves of the claw coupling together, they are available with hosetail, male and female threads.

Commonly found in many applications for industries, such as oil refineries, chemical plants, offshore rigs, construction and many more.
