Angle Valve – 1/2" x 1/2", Square, Chrome Finish

An angle valve (also called an angle stop valve) is a small plumbing valve, usually with a 90° bend, fitted between the water supply pipe and a fixture (like a basin, toilet, or washing machine).

What it’s used for:
It controls water flow to a single fixture without shutting off the main supply.
Lets you turn off water locally if you need to service or replace taps, mixers, or appliances.
Provides a connection point for flexible hoses.
?? In short: an angle valve is a convenient shut-off and connection point for plumbing fixtures.
