Parker A6MC2-MG Push-to-connect Connector 3/8in Od

Product Description

The PARKER A6MC2-MG is a push-to-connect tube-to-pipe connector fitting designed for quick, tool-free tube connections in fluid and pneumatic distribution systems. Constructed from polyoxymethylene (POM), a rigid acetal-based thermoplastic, this fitting accepts 3/8 inch OD tubing on the push-to-connect end and threads into 1/8 inch NPTF female ports on the pipe side. It is rated to 300 psi, making it suitable for moderate-pressure pneumatic and liquid line applications. Plumbers, HVAC technicians, and industrial maintenance professionals install this type of fitting where a permanent push-lock tube-to-pipe transition is needed in tight spaces or multi-line manifold setups.

This connector is intended for use in pneumatic control lines, fluid handling systems, and instrumentation tubing runs in both residential and light commercial environments. The NPTF thread form provides a pressure-tight seal on dry-fit metal or plastic pipe ports without requiring additional thread sealant in many applications, though job-site practice and applicable codes should guide sealant use. Typical install scenarios include control tubing on HVAC equipment, compressed air distribution, and water treatment plumbing where 3/8 inch OD poly tubing is routed to threaded instrument or valve ports.

Key Features

• Push-to-connect design allows tool-free tube insertion and positive tube retention
• POM (polyoxymethylene) body offers chemical resistance and dimensional stability
• Rated to 300 psi for use in moderate-pressure pneumatic and liquid service
• 1/8 inch NPTF male thread provides a pressure-tight pipe-side connection
• 3/8 inch OD tube compatibility suits common poly and nylon tubing used in HVAC and pneumatic controls
• Tan color aids visual identification in multi-line installations

Compatibility

Designed as a standard push-to-connect tube-to-pipe connector for use with 3/8 inch OD tubing and 1/8 inch NPTF threaded ports in pneumatic, fluid handling, and HVAC control line applications.

Installation Notes

This fitting is typically installed by licensed plumbers, HVAC technicians, or pneumatic system technicians. Always depressurize and isolate the system before removing or installing fittings. Ensure tube ends are cut square and free of burrs before insertion into the push-to-connect collet, as irregular cuts can compromise the internal seal. Verify that thread engagement meets the requirements of the applicable piping code, such as ASME B1.20.3 for NPTF threads, and consult local codes regarding sealant use.
