Sioux Chief 1/2" PEX-C Water Hammer Arrester

This 1/2" PEX-C crimp (F1807) water hammer arrester is great for in-line PEX-C installation for quick closing faucets. Water hammer occurs when the flow of moving water is suddenly stopped by a closing valve. If no measures are taken to control it, expensive fixtures and appliances within the plumbing system may become damaged. This can lead to fractured pipe joints, leaking valves, burst laundry hoses, and premature failure of water heaters and other appliances.
