Parker PP6TMC6 Tube Stem Adapter 3/8 Inch Nptf X 3/8 Inch Od

Product Description

The PARKER PP6TMC6 is a push-to-connect tube stem adapter designed to join a 3/8-inch OD tube to a 3/8-inch NPTF threaded port without tools or ferrules. The fitting body is molded from polypropylene, giving it resistance to a broad range of chemicals and moisture in low-pressure fluid and pneumatic lines. It is rated to 150 psi and is suited for plumbing, irrigation, water treatment, and light industrial applications where a fast, reliable push-in connection is required. Licensed plumbers, pipefitters, and maintenance technicians install this type of fitting in both new construction and service work.

This adapter is used wherever a push-to-connect tube line must terminate or transition at a threaded port. Typical applications include water filtration systems, reverse osmosis lines, compressed air distribution at low pressures, and chemical feed lines in residential and light commercial settings. The NPTF thread form provides a pressure-tight metal-to-thread seal without requiring additional sealant tape in many installations, though site conditions and applicable codes should guide that decision.

Key Features

• Push-to-connect design accepts 3/8-inch OD tubing with no ferrules or tools required
• 3/8-inch NPTF male thread for pressure-tight port connections
• Polypropylene body provides chemical resistance and lightweight construction
• Rated to 150 psi for low-pressure fluid and pneumatic service
• Tan color for quick visual identification in mixed-fitting installations

Compatibility

Designed as an OEM-style push-to-connect replacement or new-installation fitting for systems using 3/8-inch OD tubing and 3/8-inch NPTF threaded ports in low-pressure plumbing, pneumatic, or fluid-handling applications.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified maintenance technicians. Depressurize and drain the line completely before removing or installing any fitting. Ensure the tube end is cut cleanly and squarely and is free of burrs before inserting into the push-to-connect collet. Verify that the thread engagement and system pressure are within the fitting's rated limits before returning the line to service.
