Parker A5MRS6-MG Male Swivel Run Tee 5/16 in Od 3/8 in Nptf

Product Description

The PARKER A5MRS6-MG is a push-to-connect male swivel run tee tube fitting designed for fast, tool-free tube connections in pneumatic and fluid transfer systems. Constructed from polyoxymethylene (POM), a high-strength engineering thermoplastic, this fitting handles pressures up to 300 psi. The male swivel run tee configuration allows a branch outlet off a straight run while the swivel end simplifies alignment to a fixed male port. Rated for 5/16 inch OD tubing with a 3/8 inch NPTF thread, it is a compact, reliable solution for plumbers, HVAC technicians, and industrial service professionals working with small-bore pneumatic or fluid lines.

This fitting is suited for residential and light commercial applications where push-to-connect speed is preferred over compression or flare fittings. Common install scenarios include pneumatic control lines, instrument air tubing, and low-pressure fluid distribution systems. The NPTF thread provides a pressure-tight mechanical seal without the need for additional sealant tape in many applications, though field practice and system requirements should guide final sealing decisions. The gray POM body resists many common chemicals and lubricants encountered in HVAC and plumbing service environments.

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for pneumatic and fluid system lines using 5/16 inch OD tubing and 3/8 inch NPTF male threaded ports.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial mechanic. Depressurize and isolate the system completely before removing or installing any fittings. Confirm tubing is cut cleanly and squarely and that the OD is within specification before insertion to ensure a leak-free push-to-connect seal. Verify thread engagement and pressure rating compatibility with the host system before returning the line to service.
