Do It Best 400746 Straight Stop Valve 3/8 in Compression Brass

Product Description

The DO IT BEST 400746 is a 1/4-turn straight stop valve built from chrome-plated brass, designed to control water flow on supply lines serving residential and commercial appliances. The valve connects a 3/8 inch female compression inlet to a 3/8 inch compression outlet, making it a direct-fit solution for floor-routed supply lines running up to appliances such as dishwashers, ice makers, and similar fixtures. The quarter-turn operation allows fast shutoff during maintenance or new appliance installation. Licensed plumbers and experienced tradespeople are the primary installers of this valve type.

This straight stop valve is intended for water inlet lines that rise from the floor to an appliance connection point. Its straight-body configuration suits installations where the supply line and the appliance inlet are in vertical alignment. The chrome-plated brass construction resists corrosion and meets the aesthetic expectations of finished spaces. It is appropriate for both new construction and retrofit service work in residential and light commercial plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the main water supply and relieve line pressure before removing any existing valve or fitting. Compression fittings require proper seating of the ferrule against the tubing — do not overtighten, as this can deform the ferrule and cause leaks. After installation, restore water pressure gradually and inspect all connections for leaks before returning the system to service.
