Product Description

Sourced directly from DeWalt, this Pressure Seal Kit contains OEM approved replacement seals for select models of DeWalt Pressure Washers. To ensure this is compatible with your machine, please see the "Model Cross Reference List" below. This Kit contains the twelve (12) seals needed to replace the existing parts. The components are utilized to ensure tight seals between connected parts, preventing water from leaking past the high-pressure side of the piston. Over time, Seals will wear out and may begin to crack causing water leaks, at which point they need to be replaced. The Seals in the kit range in size, are made up of rubber and metal components, and each kit is sold individually.
