Parker PPB6UC6-MG Push-to-connect Union 3/8 in Od

Product Description

The PARKER PPB6UC6-MG is a push-to-connect tube-to-tube union fitting designed for fast, tool-free connections in fluid and pneumatic tubing systems. Molded from polypropylene with a black finish, it accepts 3/8 inch OD tubing on both ends and is rated to 150 psi. The push-to-connect mechanism allows a technician to make a secure, leak-resistant joint by simply inserting the tube into the fitting body without threading, soldering, or compression sleeves. It is well suited for light-to-medium duty plumbing, HVAC condensate, and industrial fluid-handling applications where quick assembly and serviceability are priorities.

This fitting is used in residential and light commercial installations wherever a straight inline tube union is needed to join two runs of 3/8 inch OD tubing. Common applications include HVAC condensate drain lines, water treatment systems, pneumatic control circuits, and similar low-to-medium pressure fluid systems. The polypropylene construction resists corrosion and many common chemicals, making it appropriate for both wet and dry service environments. Licensed plumbers, HVAC technicians, and industrial maintenance professionals typically install this fitting.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off system pressure and relieve line pressure completely before inserting or removing the fitting. Ensure the tube end is cut cleanly and squarely with no burrs before insertion, as ragged cuts can compromise the seal. To release the tube, depress the collet ring evenly while pulling the tubing straight out.
