Parker B10-4B Pneumatic Hose Coupling 1/4 in Brass

Product Description

The PARKER B10-4B is a brass pneumatic hose coupler designed for Tru-Flate automotive interchange pneumatic systems. It features a 1/4 inch body diameter with a hose barb thread type and accepts a 5/16 inch inside diameter hose. Rated to 300 psi maximum working pressure, this Series 10 coupler is built for reliable connection and disconnection in compressed air lines. The brass construction resists corrosion and holds up in demanding shop and field environments. HVAC technicians, plumbers, and general trade professionals use it wherever a Tru-Flate-style quick-connect fitting is needed in a pneumatic tool or air supply line.

This coupler is suited for residential and light commercial service environments where Tru-Flate automotive-style pneumatic couplings are the standard. It is commonly installed on air hose assemblies used with pneumatic tools in shop settings, service vans, and job sites. The hose barb end connects directly to 5/16 inch ID pneumatic hose without requiring additional adapters. At 2.49 inches overall length and 0.19 pounds, it is compact enough for tight installations without sacrificing flow capacity or pressure rating.
