The Flamco Flexofit Super 1/2" water hammer arrestor is designed to reduce water hammer in pipework systems. It helps absorb pressure surges caused by rapid closing or opening of valves and contributes to protecting both the pipework and connected equipment from excessive stress. This version is intended for potable water distribution and sanitary installations. The arrestor features a chrome-plated brass body, a butyl rubber diaphragm and a compact design with an R 1/2" connection, making it suitable for standard installations where it is necessary to reduce noise and the adverse effects of pressure shocks.
