Parker A6FC4-MG Push-to-connect Tube Fitting Connector

Product Description

The PARKER A6FC4-MG is a push-to-connect tube-to-pipe connector fitting designed for fast, tool-free tube connections in fluid and pneumatic distribution systems. It accepts 3/8 inch OD tubing and connects to a 1/4 inch NPTF threaded port. The body is molded from polyoxymethylene (POM), a rigid acetal resin chosen for chemical resistance and dimensional stability. Rated to 300 psi, this fitting is suited for compressed air, water, and compatible fluid lines in light industrial and commercial plumbing or HVAC applications. Plumbers, HVAC technicians, and pneumatic system installers use this connector to reduce assembly time compared to traditional compression or flare fittings.

This connector is a standard push-to-connect straight fitting used where a tube run must terminate or continue from a threaded pipe port. Typical installations include pneumatic control panels, fluid transfer manifolds, HVAC condensate or controls tubing, and light-duty compressed-air distribution systems. Its compact size and tan POM construction make it appropriate for environments where metal fittings are unnecessary or where corrosion resistance is a priority.

Key Features

• Push-to-connect design allows tool-free tube insertion and positive retention
• 3/8 inch OD tube connection mates with standard polyethylene, nylon, or PU tubing
• 1/4 inch NPTF male thread provides a pressure-sealing connection to pipe ports without a separate sealant in many applications
• POM (polyoxymethylene) body offers high rigidity, low friction, and broad chemical compatibility
• Rated to 300 psi for use in compressed-air and fluid-transfer lines
• Tan color allows quick visual identification on mixed-fitting installations

Compatibility

Designed as an OEM-style push-to-connect connector for systems using 3/8 inch OD tubing and 1/4 inch NPTF threaded pipe ports in pneumatic and fluid distribution applications.

Installation Notes

Depressurize and de-energize the system completely before removing or installing any fitting. Ensure the tube end is cut cleanly and squarely with no burrs before inserting into the fitting body. NPTF threads are designed to seal on thread interference, but confirm port thread condition and apply thread sealant per the system design requirements. Installation of push-to-connect pneumatic and fluid fittings should follow applicable IPC or system OEM guidelines.
