Matco-norca lr-799 Universal Rough-in Valve 1/2 Inch

Product Description

The MATCO-NORCA lr-799 is a universal rough-in valve designed for residential and light commercial plumbing installations. It accepts either a 1/2-inch female copper or 1/2-inch male inlet connection, making it adaptable across a wide range of rough-in configurations. The valve is supplied less stops, meaning field-installed stops are not included. A ceramic cartridge provides durable, reliable flow control with long service life. This valve is typically installed by licensed plumbers during the rough-in phase of construction or remodel work, before finish trim is applied.

The lr-799 is suited for use in residential bathrooms, lavatories, and similar wet areas where a universal rough-in valve is required. Its dual-connection compatibility reduces the need to stock multiple SKUs for different stub-out configurations. The ceramic cartridge design is well-regarded in the trade for resisting wear and drip compared to rubber-seat alternatives. This valve is intended for installation prior to wall close-in, with finish trim selected separately based on the specific fixture application.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the main water supply and relieve system pressure before beginning work.
