Oatey Company 38600 Washing Machine Shock Absorber 6 Pack

Product Description

The OATEY COMPANY 38600 is a washing machine supply line shock absorber designed to reduce pipe noise and water hammer in residential laundry installations. Water hammer occurs when the washing machine valve closes rapidly, sending a pressure wave through the supply line that causes loud banging or knocking in the pipes. This shock absorber installs inline on the supply line to dampen that pressure spike, protecting fittings and pipes from repeated stress. Licensed plumbers and knowledgeable DIYers install this part as a straightforward fix for noisy laundry room plumbing. Each unit is sold in a package of 6.

This shock absorber is suited for residential washing machine installations where fast-closing solenoid valves on the machine create water hammer events. It mounts at the supply line connection point, typically at the wall shut-off valve or at the machine inlet. The device is appropriate for both hot and cold supply lines. It is a common solution when homeowners report banging pipes during the wash or rinse cycle, and plumbers often install it as a preventive measure during new appliance hookups or supply line replacements.

Installation Notes

A licensed plumber or qualified technician should shut off the water supply at the main or local shut-off valve before installing this shock absorber. The supply line must be depressurized and drained before disconnecting any fittings. Installation should follow local plumbing codes, including applicable IPC requirements. Do not overtighten threaded connections, as this can damage sealing surfaces on the fitting or the machine inlet.
