Parker A5MC2-MG Push-to-connect Fitting 5/16 in Od

Product Description

The PARKER A5MC2-MG is a push-to-connect tube-to-pipe connector fitting designed for quick, tool-free tube connections in fluid and pneumatic systems. Constructed from polyoxymethylene (POM), a rigid engineering thermoplastic, this fitting accepts 5/16 inch OD tubing and threads into 1/8 inch NPTF ports. The NPTF thread form creates a pressure-tight seal without additional thread sealant under normal conditions. Rated to 300 psi, this connector suits compressed air, water, and a range of compatible fluid lines in both residential and light commercial applications. Plumbers, HVAC technicians, and pneumatic system installers are the typical end users.

This fitting is well suited for push-to-connect tubing installations where speed and reliability matter, such as pneumatic control lines, water supply connections, and instrumentation tubing runs. Its tan POM construction resists moisture and many common chemicals, making it appropriate for indoor mechanical rooms, equipment enclosures, and control panel plumbing where a compact, low-profile connector is needed. It is sold and packaged individually, making it a practical choice for service replacements or small assembly jobs.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure retention
• 5/16 inch OD tube compatibility for common small-bore tubing sizes
• 1/8 inch NPTF male thread provides a pressure-tight pipe connection
• 300 psi pressure rating suitable for pneumatic and fluid service lines
• Polyoxymethylene (POM) body offers good chemical resistance and dimensional stability
• Compact connector profile for tight-space installations

Compatibility

Designed as an OEM-style push-to-connect replacement connector for systems using 5/16 inch OD tubing with 1/8 inch NPTF threaded ports in pneumatic or fluid handling applications.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or pneumatic system technicians. Before servicing, depressurize the line completely and shut off the fluid or air supply upstream. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect fitting. Verify thread engagement into the mating NPTF port is sufficient for a leak-free seal before re-pressurizing the system.
