Description
KF Range · Professional Pneumatic Fittings
Quick-Release Air Coupling
R3/8" BSP Male Thread · 35 Bar · Steel
Engineered for compressed air systems that demand instant, leak-free connections. The KF male-thread coupling delivers one-hand operation, industrial-grade flow, and the durability to perform shift after shift in the most demanding workshop environments.
Product Overview
The KF range quick-release coupling with R3/8" BSP male thread is the professional's choice for high-cycle pneumatic connections. Its push-to-connect, pull-to-release collar mechanism allows tools and accessories to be swapped in seconds — without reaching for a spanner, without air loss, and without interrupting workflow. Constructed from heavy-duty steel with a corrosion-resistant finish, this coupling is built to withstand the rigours of automotive workshops, engineering facilities, and industrial production lines alike.
With a maximum working pressure of 35 bar (508 PSI) and a free-flow rate of 2,100 litres per minute at 6 bar, it supports the full spectrum of pneumatic tooling — from impact wrenches and spray guns to blow guns and tyre inflators — without restriction or pressure drop.
