Protect your plumbing and reduce water line noise with this Oatey 34479 Quiet Pipes E straight hammer arrestor. Featuring a 1" MIP connection, this E size straight hammer arrestor reduces banging from water line vibrations and protects your plumbing fixtures from the effects of water hammer. It's made of durable copper and installs on hot or cold water valves in any position. Plus, it doesn't require cutting into your drywall for installation!
