Description
Airflow Range · Professional Pneumatic Fittings
The coupling that holds its ground — under pressure, every time.
Engineered for demanding compressed air environments. Steel-bodied, high-flow, and rated to 14 bar — this is the fitting professionals reach for when reliability is non-negotiable.
Overview
In a busy workshop, a coupling failure isn't just an inconvenience — it's lost time, lost pressure, and lost productivity. The Airflow R 3/8" BSP Male Thread Quick-Release Coupling is built to eliminate that risk entirely.
Machined from heavy-duty steel and finished for corrosion resistance, this coupling delivers a secure, leak-free connection between your air compressor, distribution system, and pneumatic tooling. The precision-engineered locking collar engages positively under load, while the high-flow 5 mm nominal bore ensures your tools receive the full volume of air they demand — no restriction, no pressure drop.
Whether you're running an impact wrench in a commercial garage, operating spray equipment in a bodyshop, or managing a multi-drop air system on the factory floor, this fitting performs without compromise across the full operating range of -40°C to +100°C.
