The Stream33 3/4" FIP Swivel x 3/4" Male Hose Water Hammer Arrestor is crafted with a cold-rolled, spun closed seamless chamber end and a pressurized air cushion, coupled with a lead-free solder joint, ensuring a high-quality and secure connection in plumbing systems. This versatile tee fitting is ideal for branching a single water line into two separate outlets, commonly used in both residential and commercial water distribution systems for hoses and other attachments. The water hammer arrestor absorbs the shock when flowing water suddenly stops as a result of fast closing shut-off valves.
