Parker A5MC4-MG Push-to-connect Fitting 5/16 Od 1/4 Nptf

Product Description

The PARKER A5MC4-MG is a push-to-connect tube-to-pipe connector fitting designed for quick, tool-free tube connections in fluid and pneumatic plumbing systems. It accepts 5/16 inch OD tubing and connects to 1/4 inch NPTF threaded ports. The body is molded from POM (polyoxymethylene), a rigid acetal resin that resists moisture, fuels, and common hydraulic fluids. Rated to 300 psi, this fitting is suited for compressed air, light hydraulic, and fluid transfer lines where a fast, reliable push-in connection is required. Plumbers, HVAC technicians, and industrial maintenance techs use this fitting when routing tubing to threaded manifolds, valves, or equipment ports.

This fitting is appropriate for residential and light commercial applications involving pneumatic control lines, water supply tubing, or fluid handling systems. It is typically used where POM-compatible media and moderate pressures are present. The push-to-connect design speeds installation in tight spaces where wrench clearance for compression fittings is limited. The tan-colored body aids visual identification in multi-line installations.

Compatibility

Designed as an OEM-style push-to-connect connector for systems using 5/16 inch OD tubing and 1/4 inch NPTF threaded ports in pneumatic or fluid transfer applications.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC or mechanical technician. Before installation, depressurize and isolate the line completely. Ensure tubing cut ends are square and free of burrs before inserting into the push-to-connect collet. Apply appropriate thread sealant to the NPTF male threads per local plumbing code requirements before tightening into the receiving port.
