U.S. Plastic Corporation True Union Valve - Safe Lockouts with Valve 19387

Prevent unauthorized operation of valves. Hayward valve lockouts are used to prevent tampering or other unauthorized valve operation. True union design makes these valves very easy to maintain by allowing for easy removal from a piping system without breaking down piping connections. A fine pitch seal retainer thread allows for accurate compensation for seat wear. Reversible seats make it easy to get a damaged valve back in service. These valves feature a double o-ring stem seal for twice the leakage protection of valves with only a single stem seal.
