Uponor LF2897575 Stub 90 Degree Elbow 3/4 Inch Pex Brass

Product Description

The UPONOR LF2897575 is a stub 90-degree elbow fitting designed for transitioning between PEX tubing and copper pipe in residential and light commercial plumbing systems. This fitting features a PEX Brass x C (sweat copper) connection configuration, allowing a direct stub-out transition at a 90-degree angle. Constructed from lead-free brass with a copper-compatible end, it is suited for potable water applications where code compliance and material safety are required. Licensed plumbers and pipefitters install this type of fitting during rough-in work when a stubbed-out supply line must turn 90 degrees before terminating at a fixture or valve.

This elbow is sized at 3/4 inch and is intended for use in domestic water supply systems. The PEX side accepts standard PEX expansion or clamp-style connections depending on the system configuration, while the copper side is designed for standard sweat soldering. It is commonly used in new construction and remodel projects where PEX distribution lines transition to copper stub-outs at walls or floors for fixture connections.

Key Features

• 90-degree elbow configuration for directional stub-out transitions
• Lead-free brass construction suitable for potable water systems
• 3/4 inch size covers common residential supply line applications
• PEX Brass x C (sweat copper) dual-connection design

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 3/4 inch PEX-to-copper transition applications in residential domestic water supply systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC standards. Shut off the water supply and depressurize the line before cutting or sweating any connections. The copper sweat end requires standard soldering tools and flux-core solder rated for potable water use. Ensure the PEX connection method matches the system design, whether expansion-style or clamp-ring, before installation.
