Professional Pneumatic Fittings · Air Compressors UK
Multi-Fit Air Coupling
RP 1/4" BSP Female Thread
Universal quick-release coupling engineered for compressed air systems demanding consistent, leak-free performance at up to 35 bar.
The Multi-Fit Air Coupling with RP 1/4" BSP female thread is the workshop professional's choice for a reliable, universal connection point on any compressed air system. Its multi-fit profile accepts the widest range of male plug standards in common UK and European workshop use — eliminating the frustration of incompatible connectors mid-job. Built from hardened steel with precision-machined threads, it delivers a positive, vibration-resistant lock every time.
Key Features
Accepts the broadest range of male plug standards — one coupling, maximum compatibility across your tool inventory.
1800 l/min at 6 bar ensures unrestricted airflow to demanding tools — grinders, impact wrenches, and spray guns perform at full capacity.
Rated to 35 bar / 508 psi — well beyond typical workshop pressures, providing a substantial safety margin for industrial environments.
Hardened steel construction resists workshop abuse, oil contamination, and mechanical impact — built to outlast the tools it connects.
Operates reliably from −40°C to +100°C — suitable for cold stores, outdoor use, and high-heat industrial environments.
Standard parallel internal thread for direct, seal-on-face connection to BSP-threaded manifolds, hose tails, and air line ports.
