The UPONOR Q4760750 is a 90-degree elbow fitting designed for use in ProPEX expansion-style plumbing systems. Made from polysulfone, this fitting connects 3/4-inch PEX tubing at a right angle, redirecting flow within potable water, hydronic, or radiant heating distribution systems. The polysulfone construction provides resistance to high temperatures and chlorinated water, making it a dependable choice for domestic water applications. Licensed plumbers and mechanical contractors install this fitting as part of new construction or retrofit plumbing assemblies using compatible ProPEX expansion tools and rings.
This elbow is suited for residential and light commercial plumbing installations where a 90-degree directional change is needed in a 3/4-inch ProPEX line. It is appropriate for domestic hot and cold water distribution, as well as hydronic and radiant heating systems that utilize PEX-a tubing with the ProPEX expansion connection method. The domestic designation confirms the fitting meets standards for potable water contact.
Designed as an OEM-style ProPEX fitting for use with 3/4-inch PEX-a tubing in Uponor ProPEX plumbing and hydronic systems requiring a 90-degree directional change.
Installation requires a licensed plumber using a ProPEX expansion tool and the appropriate 3/4-inch ProPEX expansion rings. Shut off the water supply and relieve system pressure before beginning any fitting work. Follow applicable local plumbing codes and ASTM F1960 expansion fitting standards. Do not use crimp or clamp tools with ProPEX-style fittings, as the connection method is not interchangeable.
