Parker B13 Pneumatic Hose Coupler 1/4 in Brass Tru-flate

Product Description

The PARKER B13 is a brass pneumatic hose coupler designed for compressed air systems in automotive and industrial service environments. Built to the Tru-Flate automotive interchange standard, it accepts a 1/4-18 female NPTF threaded connection and features a 1/4 inch body diameter. Rated to 300 psi maximum working pressure and capable of handling temperatures from -40 degrees F to 250 degrees F, this coupler handles the demands of shop air tools, inflation equipment, and general pneumatic lines. Licensed HVAC technicians, auto service technicians, and industrial maintenance trades install this type of fitting as a direct threaded replacement on air supply lines and manifolds.

The B13 is suited for threaded pneumatic connections in light industrial and automotive service shop settings. Its Tru-Flate automotive interchange design allows it to mate with compatible plugs across a wide range of air tools and accessories used in vehicle service, tire inflation, and compressed air distribution systems. The female NPTF thread provides a pressure-tight mechanical seal without the need for additional sealant tape in many applications, though local practice and system requirements should govern final assembly decisions.

Installation Notes

Depressurize the air line completely before removing or installing any pneumatic coupler. Thread engagement should be made with an appropriately sized open-end or adjustable wrench on the 0.75 inch hex — do not grip the coupler body. Follow applicable shop safety standards and local codes for compressed air system service. Inspect the mating plug and coupler for wear or damage before returning the system to service.
