39177 Hammer Arrestor, Low-Lead, Copper

Water hammer—the loud banging noise in your pipes when a valve closes abruptly—can damage plumbing appliances, fixtures, and valves over time. The Oatey Quiet Pipes Water Hammer Arrestor solves this problem by absorbing the shock of sudden water pressure changes in your supply line. When a valve shuts quickly, water flows into the arrestor's pressurized chamber where the shock is absorbed, then dissipated safely through the rest of the water line, eliminating noise and protecting your plumbing investment.

This arrestor is designed for use on both hot and cold water valves and can be installed in any direction—horizontally, vertically, or anywhere in between—without requiring any drywall cutting. Its compact size fits easily in tight spaces. Oatey has earned the trust of plumbing professionals for over 100 years, and this product reflects that commitment to quality and reliability.
