Parker 14 Tru-flate Pneumatic Hose Coupler 3/8 Male Nptf

Product Description

The PARKER 14 is a male NPTF pneumatic hose coupler designed for automotive and industrial compressed-air systems. Built from steel with a zinc chromate finish for corrosion resistance, this coupler features a 3/8-inch body diameter and a 3/8-18 male NPTF threaded connection. It is part of the Tru-Flate series, a widely recognized standard in automotive shop air systems. Licensed HVAC technicians, automotive mechanics, and general contractors use this style of coupler to connect air hoses and pneumatic tools to shop compressor lines quickly and securely.

This coupler is suited for automotive service bays, general shop environments, and light industrial settings where Tru-Flate style pneumatic connections are the prevailing standard. It threads directly onto equipment ports, hose ends, or manifold fittings with a 3/8-18 NPTF male thread, providing a pressure-tight seal without a separate pipe-thread sealant in many applications. It is a common replacement or expansion fitting when adding drop lines or reconfiguring shop air layouts.

Installation Notes

Installation is performed by a qualified technician or experienced tradesperson familiar with compressed-air systems. Always depressurize and bleed down the air line before removing or installing any coupler. Use appropriate thread sealant or PTFE tape on NPTF threads as required by the application. Tighten with a wrench to proper engagement — do not overtighten steel fittings into soft-metal ports.
