Parker PP8UC6 Push-to-connect Union Fitting 1/2 X 3/8 in

Product Description

The PARKER PP8UC6 is a push-to-connect tube union fitting designed to join two tubes with outside diameters of 1/2 inch and 3/8 inch in a single, tool-free connection. The body is molded from polypropylene with an EPDM o-ring seal, making it suitable for use in fluid transfer and low-pressure pneumatic or fluid lines rated up to 150 psi. The fitting connects and disconnects without thread tools or solvents, which speeds up installation and serviceability on plumbing, HVAC condensate, and light industrial fluid systems. Plumbers, HVAC technicians, and facilities maintenance professionals use this fitting in applications where quick tube connections are required.

This fitting is appropriate for residential and light commercial applications involving tube-to-tube connections in water supply, condensate drain lines, and similar low-pressure fluid systems. The push-to-connect design allows the installer to seat the tube by hand with a single straight push, reducing installation time compared to compression or threaded fittings. The polypropylene body and EPDM o-ring combination provide chemical compatibility with water and many common non-hydrocarbon fluids encountered in plumbing and HVAC service work.

Key Features

• Tool-free push-to-connect design for fast, repeatable tube connections
• Connects 1/2 inch OD tube to 3/8 inch OD tube in a single union body
• Polypropylene construction with EPDM o-ring seal for water and fluid compatibility
• Rated to 150 psi for low-pressure fluid and pneumatic service
• White color for easy identification in condensate and water line applications

Compatibility

Designed as an OEM-style push-to-connect replacement union for low-pressure tube systems using 1/2 inch and 3/8 inch outside diameter tubing in plumbing and HVAC condensate applications.

Installation Notes

Installation is performed by cutting the tube square, deburring the cut end, and inserting the tube firmly into the fitting body until it seats. Shut off the fluid or air supply and relieve system pressure before disconnecting or replacing any fitting. To release the tube, depress the collet release ring while pulling the tube free. Verify all connections are fully seated and leak-test the system at operating pressure before returning to service.
