Parker A8MRS8-MG Male Swivel Run Tee 1/2 in Od Nptf

Product Description

The PARKER A8MRS8-MG is a push-to-connect male swivel run tee tube fitting designed for fast, tool-free connections in pneumatic and fluid tubing systems. Molded from polyoxymethylene (POM), a rigid engineering-grade thermoplastic known for chemical resistance and dimensional stability, this fitting accepts 1/2-inch OD tubing on the push-to-connect ports and features a 1/2-inch NPTF male swivel thread on the branch outlet. Rated to 250 psi, it suits pressurized air and compatible fluid distribution lines. The swivel thread design allows the male port to rotate during installation, reducing torque stress on adjacent tubing and fittings. Plumbers, HVAC technicians, and pneumatic system assemblers install this type of fitting where a tee branch must align to a fixed port without twisting the run tubing.

This fitting is suited for residential and light commercial pneumatic tubing runs, compressed air distribution panels, and fluid control manifolds where a run-tee configuration is required. The push-to-connect mechanism accepts 1/2-inch OD tubing — typically polyethylene, nylon, or equivalent semi-rigid tubing — and allows quick-release disconnection when the collet is depressed, which simplifies serviceability in tight enclosures or control cabinets. The gray POM body color aids visual identification in multi-line assemblies. This fitting is sold and shipped individually.

Key Features

• Push-to-connect design for tool-free, quick-release tubing installation and removal
• 1/2-inch OD tubing compatibility on push-to-connect ports
• 1/2-inch NPTF male swivel thread branch for torque-free port alignment
• POM (polyoxymethylene) body rated to 250 psi for pressurized pneumatic and fluid service
• Run tee configuration maintains in-line flow while adding a perpendicular branch outlet
• Gray body color for easy identification in multi-line systems

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic and fluid tubing systems using 1/2-inch OD semi-rigid tubing with 1/2-inch NPTF male thread connection points. Verify thread type and tubing material compatibility with system fluid and pressure requirements before installation.

Installation Notes

Depressurize and isolate the tubing system completely before removing or installing any push-to-connect fittings. Insert tubing fully into the collet until it seats against the internal stop to ensure a leak-free connection. NPTF threads are designed to seal on the thread form without sealant tape, but consult applicable codes and manufacturer guidance for your specific fluid service. Inspect tubing ends for squareness and burrs before insertion — deformed tubing ends can compromise the collet seal.
