Parker A6FC8-MG Push-to-connect Connector 3/8 Od 1/2 Nptf

Product Description

The PARKER A6FC8-MG is a push-to-connect tube-to-pipe connector fitting designed for use in compressed air, pneumatic, and fluid transfer systems. It accepts 3/8 inch OD tubing and connects to a 1/2 inch NPTF threaded port. The body is molded from polyoxymethylene (POM), a rigid acetal resin that resists moisture, fuels, and many solvents. The fitting is rated to 300 psi, making it suitable for moderate-pressure pneumatic and liquid service. Installation requires no tools on the tube side — tubing inserts and locks with a single push. The tan color is standard for this product family and aids visual identification on complex plumbing runs.

This fitting is used in residential and light commercial HVAC systems, pneumatic control lines, condensate management assemblies, and general-purpose plumbing where a quick, leak-free tube-to-pipe connection is needed. It is commonly installed by HVAC technicians, plumbers, and industrial maintenance personnel in equipment panels, control assemblies, and utility piping where 3/8 inch OD tubing terminates at a threaded port. The NPTF thread form provides a pressure-tight mechanical seal without the need for additional thread sealant in most applications.

Key Features

• Push-to-connect design accepts 3/8 inch OD tubing with no tools required on the tube side
• 1/2 inch NPTF male thread for a pressure-tight connection to standard pipe ports
• Polyoxymethylene (POM) body rated to 300 psi service pressure
• Resistant to moisture, fuels, and common solvents encountered in HVAC and plumbing applications
• Tan color for easy visual identification in multi-line installations
• Compact, lightweight construction at 0.05 pounds

Compatibility

Designed as a direct-connect fitting for 3/8 inch OD tubing terminating at 1/2 inch NPTF threaded ports in pneumatic, HVAC, and general-purpose fluid plumbing assemblies.

Installation Notes

This fitting is typically installed by licensed plumbers, HVAC technicians, or industrial piping mechanics. Before installation, depressurize the system completely and verify the mating port threads conform to NPTF standards. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect collet — ragged cuts are a leading cause of joint leakage. To remove tubing, depress the collet release ring while pulling the tube free; do not yank the tube without releasing the collet or fitting damage may result.
