GUOFIS 20 Pack Angle Stop Valve - 1/2 Nominal (5/8in OD) Inlet x 3/8in OD Outlet, 1/4 Turn

Reliable shut-off for everyday plumbing tasks

The GUOFIS 20 Pack Angle Stop Valves offer dependable control for fixtures and appliances that need a quick, localized shut-off. Crafted with a lead‑free brass body and a chrome‑plated finish, these valves resist corrosion in humid spaces while delivering a clean, professional look under sinks or behind walls. Certified to meet drinking water standards, they provide a practical balance of safety, durability, and performance for residential and commercial use.

Designed for straightforward installations, each valve uses compression fittings compatible with copper or PEX piping. The configuration matches a 5/8" compression inlet to fit 1/2" supply lines, and a 3/8" compression outlet to connect hoses for toilets and faucets. A quarter-turn lever keeps control precise and intuitive, allowing you to isolate a single appliance without interrupting water to other fixtures.

This set includes 20 valves, making it a sensible choice for projects that involve multiple fixtures or ongoing maintenance. The robust stainless/brass combination withstands regular use and fluctuating temperatures in hot and cold water systems, while the chrome finish helps maintain a polished appearance over time.
