Parker PP4MRS4 Male Swivel Run Tee 1/4 in Od Nptf Polypropylene

Product Description

The PARKER PP4MRS4 is a push-to-connect male swivel run tee tube fitting designed for tube-to-pipe connections in fluid transfer and pneumatic systems. Constructed from white polypropylene, it accepts 1/4 inch OD tubing and features a 1/4 inch NPTF male swivel thread. The run tee configuration allows a branch takeoff while maintaining inline flow through the run ports. Rated at 150 psi, this fitting suits low-to-medium pressure applications. Installation requires no tools on the tube side — tubing inserts directly into the push-to-connect port and locks in place. Plumbers, HVAC technicians, and fluid system installers use this fitting where a compact, corrosion-resistant connection point is needed.

This fitting is suited for residential and light commercial plumbing, HVAC condensate lines, pneumatic control tubing, and chemical fluid transfer applications where polypropylene compatibility is required. The swivel feature on the male threaded end allows thread engagement without twisting the connected tubing, simplifying installation in tight or confined spaces. It is typically used with 1/4 inch OD semi-rigid or flexible tubing in systems requiring a tee branch at a pipe connection point.

Key Features

• Push-to-connect design accepts 1/4 inch OD tubing without tools or ferrules
• Male swivel NPTF thread eliminates torsional stress on tubing during installation
• Polypropylene construction resists corrosion and many common chemicals
• Rated to 150 psi for low-to-medium pressure service
• Run tee configuration maintains inline flow with a side branch port
• White color finish for easy visual identification in multi-line systems

Compatibility

Designed for use with 1/4 inch OD tubing and 1/4 inch NPTF male threaded pipe connections in push-to-connect plumbing and pneumatic systems.

Installation Notes

Shut off system pressure and depressurize all lines before installing or removing push-to-connect fittings. Ensure tubing is cut square and free of burrs before inserting into the push-to-connect port to achieve a proper seal. NPTF threads are self-sealing by design, but apply thread sealant tape or compound as required by local plumbing codes. A licensed plumber or qualified technician should verify pressure ratings and chemical compatibility before installation.
