Plumb Shop MP2780PCLF Angle Stop Valve 1/2 Sweat X 3/8 Comp Chrome

Product Description

The PLUMB SHOP DIV BRASSCRAFT MP2780PCLF is a 1/4-turn angle supply stop valve designed for residential and light commercial plumbing supply lines. It connects a 1/2-inch copper sweat inlet to a 3/8-inch OD compression outlet, making it a standard fit for sink, lavatory, and toilet supply connections. The chrome finish suits exposed under-sink installations where appearance matters. Constructed to lead-free standards, it meets current potable water compliance requirements. The 1/4-turn ball-style operation allows fast shutoff without multiple handle rotations, which is useful during service calls where quick isolation is needed. Licensed plumbers and experienced plumbing technicians are the primary installers of this valve type.

This angle stop is suited for residential bathroom and kitchen applications where a copper sweat supply line feeds a fixture shutoff point. Typical installations include under lavatory sinks, kitchen sinks, and toilet supply connections where the supply line transitions to a 3/8-inch OD compression fitting. It is appropriate for new construction rough-in and retrofit replacement of older stop valves on existing copper supply lines. The chrome finish blends with standard fixture trim in finished spaces.

Installation Notes

Installation is performed by a licensed plumber or qualified plumbing technician. Shut off the main water supply and relieve line pressure before sweating the inlet connection or disturbing the existing stop. The sweat end requires standard copper soldering practice in accordance with applicable IPC and local plumbing code requirements. Verify compression nut is hand-tightened then snugged with a wrench — do not overtighten the compression fitting, as this can crack the ferrule or distort the seat.
