Parker PP8EU8 Push-to-connect Union Fitting 1/2 in Od

Product Description

The PARKER PP8EU8 is a push-to-connect union tube fitting designed to join two lengths of 1/2-inch OD tubing without tools or solvents. The fitting body is molded from polypropylene with an EPDM O-ring seal, making it suitable for water and fluid transfer lines where lightweight construction and corrosion resistance matter. Rated at 150 psi, it provides a reliable, leak-resistant connection in plumbing, irrigation, water treatment, and light industrial fluid systems. Plumbers, irrigation technicians, and water treatment specialists install this fitting as a quick, removable union between tube runs.

This fitting is used in residential and light commercial plumbing, pool and spa water lines, irrigation distribution systems, and water treatment equipment where polypropylene construction is preferred over metal. The push-to-connect design allows fast inline connections without crimping tools, compression sleeves, or solvent cement. It is suited for applications requiring periodic disconnection of tube runs for service or maintenance.

Compatibility

Designed as an OEM-style replacement or new-installation union fitting for 1/2-inch OD tube runs in plumbing, irrigation, and water treatment systems that accept push-to-connect polypropylene fittings.

Installation Notes

This fitting is installed by plumbers and irrigation technicians working with 1/2-inch OD tubing in low- to medium-pressure water systems. Ensure the tube end is cut cleanly and squarely and is free of burrs before insertion to maintain a leak-free seal. Shut off and depressurize the water supply before making or breaking any connection. Consult local plumbing codes and IPC guidelines for approved materials and pressure limits in potable water applications.
