R 1/4" BSP Male Thread Brass Quick-Release Air Coupling | Non-Corrodible

Non-Corrodible Range · Professional Grade 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. 14 Bar / 200 PSI Rated 43 CFM Flow Rate Solid Brass Construction Rectus 19 Interchange UK Stock · Fast Dispatch Overview 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.

Typical Applications Workshop & GarageAir compressors, pneumatic tools, tyre inflators ManufacturingIndustrial compressed-air pipework and manifolds AutomotiveBody shops, MOT bays, spray booths Corrosive EnvironmentsHumid, coastal, or chemical-adjacent installations Air DistributionRegulators, filter units, FRL assemblies Plant & FacilitiesMaintenance air lines, production equipment Installation Fully isolate and depressurise the air system before beginning. Apply PTFE tape or a suitable pneumatic thread sealant to the R 1/4" male thread. Thread into the female-threaded port by hand until finger-tight. Use a spanner on the hex body to tighten — do not overtighten. Re-pressurise and check for leaks before returning to service.
