Description
R 1/4" BSP Male Thread
Brass Quick-Release Air Coupling
Precision-machined solid brass. 14 bar rated. Rectus 19 interchange profile.
Engineered for demanding compressed-air environments where corrosion is not an option.
A quick-release coupling that earns its place in a professional air system. Machined from solid brass with a natural finish, this R 1/4" BSP male-thread coupling delivers the corrosion resistance, flow capacity, and mechanical integrity that workshops, manufacturing plants, and industrial facilities demand.
The knurled release sleeve provides a positive, tactile grip even with gloved hands, while the precision-machined hex body allows clean installation with a standard spanner — no slipping, no rounding. Rated to 14 bar (200 PSI) with a 43 CFM flow rate at 100 PSI, it will not become the bottleneck in your air system.
