Parker A5MRS2-MG Male Swivel Run Tee 5/16 Od 1/8 Nptf

Product Description

The PARKER A5MRS2-MG is a push-to-connect male swivel run tee tube fitting designed for fast, tool-free tubing connections in pneumatic and fluid transfer systems. Constructed from polyoxymethylene (POM), a high-strength acetal resin, the fitting delivers a rated working pressure of 300 psi. The male swivel run tee configuration allows a branch port to split flow while the inline run passes straight through, making it a practical choice when routing tubing in tight plumbing or instrumentation layouts. The 1/8 inch NPTF male thread provides a pressure-tight mechanical seal without sealant tape in properly prepared ports.

This fitting is suited for residential and light commercial pneumatic control systems, instrumentation tubing runs, and low-pressure fluid lines where 5/16 inch OD tubing is used. The push-to-connect mechanism accepts tubing insertion without ferrules or compression sleeves, reducing assembly time during panel builds, OEM equipment assembly, or field service repairs. HVAC technicians, plumbers, and instrumentation technicians commonly install this type of fitting in control-line and pilot-air applications.

Key Features

• Push-to-connect design accepts 5/16 inch OD tubing without additional fittings or tools
• Male swivel run tee configuration splits flow with inline and branch ports in a single body
• Polyoxymethylene (POM) construction resists wear and provides rigidity in pneumatic service
• Rated to 300 psi working pressure
• 1/8 inch NPTF male thread for pressure-tight port connections
• Gray color for visual identification in multi-line plumbing assemblies

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic and low-pressure fluid systems using 5/16 inch OD tubing with 1/8 inch NPTF ported components.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or instrumentation technicians working on pneumatic or fluid control lines. Before servicing any pressurized line, depressurize the system fully and verify zero pressure before making or breaking connections. Tubing should be cut cleanly and squarely with a tube cutter to ensure proper seating and a leak-free push-to-connect engagement. Verify NPTF thread compatibility at the mating port before assembly, as NPTF and NPT threads have different sealing characteristics.
