Parker A8TMC6 Push-to-connect Tube Stem Adapter

Product Description

The PARKER A8TMC6 is a push-to-connect tube stem adapter designed to join 1/2 inch OD tubing to a 3/8 inch NPTF threaded port. Constructed from polyoxymethylene (POM), a high-strength acetal thermoplastic, this fitting delivers a rated working pressure of 250 psi. The push-to-connect mechanism allows for tool-free tube insertion and a secure, leak-resistant seal without additional fittings or sealant on the tube end. HVAC technicians, plumbers, and fluid-handling professionals use this style of fitting where quick, reliable connections are required in pneumatic or fluid lines.

This adapter is suited for residential and light commercial applications involving compressed air, water, or compatible fluid systems. It is commonly installed where a push-to-connect tube line must transition to an NPTF threaded port on a valve, manifold, solenoid, or equipment panel. The tan POM construction resists moisture and many common chemicals encountered in HVAC and plumbing service environments.

Installation Notes

Installation should be performed by a qualified HVAC technician or plumber. Depressurize and isolate the fluid or pneumatic system before removing or installing any fittings. Ensure the tube end is cut square and free of burrs before inserting into the push-to-connect port. Verify thread compatibility with the receiving port before applying torque to prevent damage to the POM body.
