Parker 14-5B Pneumatic Hose Coupling 3/8 Inch Tru-flate

Product Description

The PARKER 14-5B is a steel pneumatic hose coupler designed for compressed air systems using the Tru-Flate Automotive interchange standard. It features a 3/8-inch body diameter with a hose barb thread type, connecting directly to 3/8-inch inside diameter hose. The coupler is rated to 300 psi maximum working pressure and handles temperatures from -40 degrees F to 250 degrees F. A zinc chromate finish provides corrosion resistance in shop and field environments. At 2.86 inches overall length, it is a compact, direct-replacement coupler for automotive-style pneumatic quick-disconnect setups. Licensed HVAC technicians, plumbers, and general mechanical trades install this type of coupler in air tool and pneumatic control line applications.

The PARKER 14-5B is suited for residential and light commercial compressed air systems where Tru-Flate Automotive interchange couplers are the shop standard. Typical applications include air tool connections, pneumatic hose assemblies, and shop air distribution lines. The hose barb end accepts 3/8-inch ID rubber or reinforced pneumatic hose. Series 10 designation identifies it within the Parker coupler product family. No input data names specific compatible models or replacement part numbers beyond the Tru-Flate Automotive interchange standard.

Installation Notes

Depressurize the air line completely before disconnecting or installing any pneumatic coupling. Mechanical trades should verify the hose inside diameter matches the 3/8-inch barb before assembly and secure the hose with an appropriate clamp rated for the working pressure. Inspect the coupler body and barb for damage before placing the line back in service. Follow applicable OSHA and shop safety standards for compressed air systems.
