Uponor 39175 Pex-a Expansion Ring Sleeve 0.5 in 50pk

Product Description

The UPONOR 39175 is a 1/2-inch PEX-A expansion ring and sleeve designed for use with PEX-A tubing in hydronic and plumbing systems. These rings work with the expansion fitting method, where the ring and tube end are expanded simultaneously before being seated over a fitting, creating a leak-resistant connection as the PEX memory contracts. Sold in a bag of 50, this part is installed by licensed plumbers and hydronic technicians working on residential or light commercial water distribution and radiant heating systems.

These expansion rings are suited for 1/2-inch PEX-A piping applications, including potable water supply lines, radiant floor heating loops, and hydronic distribution manifolds. The expansion fitting method is commonly specified where long-term joint reliability and freeze-damage recovery are priorities. Each bag provides 50 rings, making it practical for rough-in work where multiple connections are completed in a single service visit.

Key Features

• Sized for 1/2-inch PEX-A tubing, compatible with the expansion fitting connection method
• Bag of 50 rings supports multi-connection rough-in and service work
• Designed for use with expansion-style fittings where PEX memory provides the sealing force
• Suitable for potable water and hydronic heating applications

Compatibility

Designed as an OEM-style expansion ring for use with 1/2-inch PEX-A tubing and compatible expansion-style fittings in residential and light commercial plumbing and hydronic heating systems.

Installation Notes

Installation is performed by licensed plumbers or hydronic technicians using a PEX expansion tool rated for 1/2-inch tubing. Shut off the water supply and depressurize the line before beginning work. Slide the expansion ring onto the tubing before expanding the tube end, then seat the expanded assembly over the fitting and allow the PEX to contract fully before pressurizing. Follow all applicable local plumbing codes and ASTM F1960 expansion fitting standards.
