Parker 0C Pneumatic Hose Coupling 1/4 in Tru-flate Steel

Product Description

The PARKER 0C is a male NPT pneumatic hose coupling connector designed for compressed air and pneumatic tool applications. Built to the Tru-Flate Automotive interchange standard, it connects pneumatic hoses and tools using a 1/8-27 MNPT threaded connection and features a 1/4 inch body diameter. Constructed from steel with a zinc chromate finish, it is rated for working pressures up to 300 psi and temperatures ranging from -40 degrees F to 250 degrees F. Licensed HVAC technicians, plumbers, mechanics, and industrial maintenance technicians use this connector in air distribution systems and pneumatic tool setups.

This coupling connector is suited for residential and light commercial pneumatic installations where Tru-Flate Automotive interchange compatibility is required. It is a Series 10 connector and threads directly into standard NPT-ported equipment, fittings, manifolds, and air line components. The 1/8-27 thread size makes it a common choice for small-diameter pneumatic tool inlets, compressor accessories, and inline pneumatic fittings requiring a compact, threaded male connector.

Compatibility

Designed as an OEM-style replacement or new-installation connector for pneumatic systems using the Tru-Flate Automotive interchange standard with 1/8-27 NPT threaded ports.

Installation Notes

Installation is performed by qualified mechanics, HVAC technicians, or industrial maintenance personnel familiar with pneumatic systems. Depressurize the air line completely before removing or installing any coupling or connector. Use thread sealant or PTFE tape on the MNPT threads in accordance with the fitting manufacturer guidelines and applicable codes. Do not overtighten threaded fittings; use an appropriately sized wrench on the hex flat to achieve a secure, leak-free connection without stressing the fitting body.
