• Purpose. Installed on wall water supply lines to control or completely shut off water flow to individual fixtures—such as toilet cisterns, washbasins, kitchen faucets, or water heaters—without cutting water to the entire house.
• Build & Specs. As noted on its packaging, it features a polished chrome finish, a solid brass body, and a drip-free washerless cartridge (typically a quarter-turn ceramic disc) for quick shut-off.
• Connections. Standard 1/2-inch male BSP threads on both the wall inlet (longer threaded end) and the 90-degree outlet (shorter threaded end for a flexible braided hose).
