Uponor LF4235050 90 Deg Drop-ear Elbow 1/2 in Propex Fnpt Brass

Product Description

The UPONOR LF4235050 is a 90-degree drop-ear elbow designed for use in ProPEX expansion-style PEX plumbing systems. It features a ProPEX inlet on one end and a female NPT (FNPT) threaded outlet on the other, allowing a direct transition from PEX tubing to a threaded fixture connection. Constructed from lead-free brass, this fitting meets modern potable water requirements. It is primarily installed by licensed plumbers working on residential and light commercial water distribution systems where a wall-mounted fixture connection is required, such as shower arms or wall-outlet supply points.

This drop-ear elbow is suited for in-wall rough-in applications where the fitting must be secured to framing before drywall installation. The ear flanges allow the fitting to be fastened to a backing plate or stud, keeping the threaded outlet stationary and preventing pipe movement at the fixture connection point. It is used with 1/2 inch nominal ProPEX PEX tubing and pairs with standard 1/2 inch FNPT threaded fixtures and adapters.

Key Features

• 90-degree elbow with integrated mounting ears for solid attachment to wall framing
• ProPEX inlet compatible with Uponor ProPEX expansion tooling and rings
• 1/2 inch FNPT threaded outlet for direct connection to wall-mount fixtures
• Lead-free brass construction suitable for potable water applications
• Domestic product designation

Compatibility

Designed for use with 1/2 inch nominal ProPEX PEX tubing systems using Uponor ProPEX expansion-style connections.

Installation Notes

Installation requires Uponor ProPEX expansion tooling and the appropriate PEX expansion rings — standard crimp or clamp tools are not compatible with ProPEX fittings. Fasten the ear flanges securely to wall framing or a backing plate before closing the wall cavity. Shut off the water supply and depressurize the system before making any connections. Work must comply with applicable local plumbing codes and IPC guidelines for PEX installations.
