Sharkbite COMPA1238Z4 Ball Valve 1/2x3/8 Compression 4 Pack

Product Description

The SHARKBITE COMPA1238Z4 is a quarter-turn, full-port brass ball valve designed for plumbing supply line connections. This 4-pack includes valves sized at 1/2-inch (5/8-inch OD) compression inlet by 3/8-inch OD compression outlet. The full-port design minimizes flow restriction, and the quarter-turn handle provides fast, reliable shutoff without tools. Connection is made using the supplied compression nut and ferrule, tightened with a standard wrench. Licensed plumbers and experienced DIYers install these valves as supply stops for toilets, faucets, and ice maker lines in residential systems.

These compression-style angle stop valves are suited for residential plumbing applications where a reliable shutoff is needed at the fixture. Common installations include under-sink faucet supply, toilet tank fill connections, and refrigerator ice maker lines. The compression fitting design is compatible with copper pipe. The 4-pack quantity supports multi-fixture jobs or service stock. This valve is installed where the main supply transitions to a smaller-diameter fixture supply line.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the main water supply and relieve line pressure before removing any existing valve. Slide the compression nut and ferrule onto the pipe before seating the valve body, then tighten the compression nut firmly with a wrench — do not overtighten, as this can deform the ferrule. Connect the fixture supply line to the 3/8-inch outlet and restore water pressure slowly, checking for leaks at both compression joints.
