This Jones Stephens washing machine outlet box is designed with quarter-turn valves to provide convenient and quick water supply shut-off access in the event of a leak or broken hose. The integrated water hammer arrestor absorbs the impact to pipes when flowing water suddenly stops and prevents knocking noises in the pipe. Compact in design, this right outlet box features a 1/2 inch PEX F1960 connection and includes all necessary parts for installation and testing. All parts are designed with quality engineering and construction to be durable and reliable to meet Jones Stephens’ highest quality standards.
