Parker PP4MRS2 Male Swivel Run Tee 1/4 in Od 1/8 in Nptf

Product Description

The PARKER PP4MRS2 is a push-to-connect male swivel run tee tube fitting designed for fast, tool-free tube connections in pneumatic and fluid handling lines. Molded from polypropylene and finished in white, this fitting accepts 1/4 inch OD tubing on the run ports while providing a 1/8 inch NPTF male swivel thread on the branch outlet. Rated to 150 psi, the PP4MRS2 is suited for low-pressure air and compatible fluid service where a tee branch with a rotatable male thread simplifies routing and alignment during assembly. HVAC technicians, refrigeration service pros, and industrial maintenance crews commonly install this fitting where quick tube insertion without compression tooling is required.

This fitting is used in residential and light commercial pneumatic control lines, condensate management assemblies, instrumentation tubing, and other low-pressure fluid distribution applications. The swivel feature on the male thread branch allows the fitting body to rotate during installation, reducing torque transfer to connected tubing and making it easier to achieve proper thread engagement in tight spaces without stressing the run ports.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Male swivel branch rotates to ease thread engagement and reduce tube stress
• 1/4 inch OD tubing compatibility on run ports
• 1/8 inch NPTF male thread on branch outlet
• Polypropylene construction offers corrosion resistance for compatible fluid service
• 150 psi pressure rating for low-pressure pneumatic and fluid lines

Compatibility

Designed as an OEM-style push-to-connect fitting for systems using 1/4 inch OD tubing with a 1/8 inch NPTF male swivel branch connection in low-pressure pneumatic or fluid handling applications.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or instrumentation technicians. Depressurize and isolate the line completely before disconnecting or installing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely and is free of burrs before insertion to achieve a proper seal. Verify thread sealant compatibility with polypropylene before applying to the NPTF branch thread, and do not overtighten the swivel connection.
