MOEN 2580 M-PACT Posi-Temp 4-Port Rough-In Valve, 1/2" Crimp PEX Inlets/CC Outlets

The MOEN 2580 M-PACT Posi-Temp rough-in valve provides pressure-balanced temperature control for compatible tub-and-shower or shower-only installations. Its four-port brass body uses 1/2-inch crimp-ring PEX inlets with CC copper-sweat outlets and includes an adjustable temperature limit stop and MOEN 1222 cartridge.

Features & Details
