These nipples and valves are made of chrome-plated brass. The valves are 1/4 turn off and on ball valves with the exception of the 3/8OD compression x compression stop valve. The 3/8OD side of the valve connects to a supply line for a toilet or sink faucet. The 3/8 and 1/2 female threaded valves are used with the chrome nipples. The chrome nipples connect to plumbing coming from behind the wall or under the floor. There are valves to connect to PEX tubing, CPVC plastic, copper tubing and threaded pipe nipples.
When using flexible stainless steel supplies with the chrome valves, discard the 3/8OD nut and ferrule from the valve. Attach the flexible supply directly to the valve.
