The Sioux Chief Hydra-Rester Hangell is engineered to absorb water hammer shock, preventing pipe damage and reducing noise in plumbing systems. Built from seamless Type L copper, the Hydra-Rester utilizes a piston with EPDM O-rings, lubricated with approved 111 Silicone Compound, to compress air and dissipate pressure waves caused by shuttering fixtures. Its design allows easy installation with versatile BSP male thread fittings, suitable for domestic, commercial, and industrial environments.
