Parker PPB4TU4-MG Union Tee Fitting 1/4 in Od Polypropylene

Product Description

The PARKER PPB4TU4-MG is a push-to-connect tube-to-tube union tee fitting designed for quick, tool-free connections in fluid and pneumatic line installations. Constructed from polypropylene with a black finish, this fitting accepts 1/4-inch OD tubing on all three ports and is rated to 150 psi. The union tee configuration allows a single inline tube run to branch off in a third direction without additional adapters or fittings. Plumbers, HVAC technicians, and industrial service pros use push-to-connect fittings to speed up repairs and new installations where copper sweat or threaded connections are impractical or unnecessary.

This fitting is suited for residential and light commercial applications including condensate drain lines, RO and water filtration systems, pneumatic control tubing, and low-pressure fluid distribution. All three ports accept 1/4-inch OD tubing, making it a straightforward tee junction for systems already plumbed with that tube size. The polypropylene body is compatible with many common tubing materials used in these applications.

Key Features

• Push-to-connect design requires no tools for tube insertion
• Rated to 150 psi for low-pressure fluid and pneumatic service
• Polypropylene construction offers corrosion resistance in moisture-prone environments
• Union tee configuration connects three 1/4-inch OD tube lines in a single fitting
• Black color for easy identification in multi-line installations
• Compact dimensions: 0.81 x 0.66 x 0.85 inches for tight-space routing

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for systems using 1/4-inch OD tubing in low-pressure fluid or pneumatic applications.

Installation Notes

Shut off the fluid or air supply and depressurize the line before disconnecting or installing any fitting. Ensure tubing ends are cut cleanly and squarely with a tube cutter for a proper seal — ragged or angled cuts cause leaks. To release tubing, depress the collet ring while pulling the tube free. Verify the system operating pressure does not exceed the 150 psi rating of this fitting.
