Bsc Preferred DIB53PCLF Quarter Turn Shut-off Valve

Product Description

The BSC PREFERRED DIB53PCLF is a straight quarter-turn shut-off valve designed for residential and light commercial plumbing supply lines. It connects a 1/2-inch female iron pipe (FIP) inlet to a 3/8-inch OD compression outlet, making it a standard fit for sink and toilet supply connections. The valve features a chrome finish and a corrosion-resistant ball for reliable, long-life operation. Lead content on wetted surfaces is limited to no more than 0.25% weighted average, meeting federal lead-free requirements for potable water systems. Licensed plumbers and experienced service technicians install this valve as part of fixture rough-in and replacement work.

This valve is suited for under-sink and toilet rough-in installations in residential bathrooms, kitchens, and utility spaces. The straight body configuration works where the supply stub-out comes directly from the wall or floor in line with the fixture supply tube. The compression outlet accepts standard 3/8-inch OD tubing, which is the most common size for faucet and toilet fill valve supply lines. The quarter-turn operation allows fast shutoff during fixture service without the gradual wear associated with multi-turn valves.

Compatibility

Designed as an OEM-style replacement or new-installation shut-off valve for residential and light commercial plumbing systems using 1/2-inch FIP supply connections and 3/8-inch OD compression supply tubes.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the main water supply and relieve line pressure before removing the existing valve or making connections. Hand-tighten the compression fitting first, then snug with a wrench — do not overtighten, as over-compression can deform the ferrule and cause leaks. Inspect for leaks at both the FIP and compression connections after restoring water pressure.
