Zurn 954-18S Check Seat 950XL 975XL Backflow Preventer

Product Description

The ZURN 954-18S is a replacement check seat designed for use in Wilkins-series backflow preventers. The check seat is an internal sealing component that maintains directional flow control within a reduced-pressure zone or double-check backflow preventer assembly. It provides a seating surface for the check valve disc to close against, helping maintain a watertight seal under normal operating conditions. This part is sized for 1-1/4 to 2 inch valve bodies and is installed by licensed plumbers or backflow prevention specialists during scheduled maintenance or repair of existing assemblies.

This check seat fits Wilkins 950XL and 975XL backflow preventer assemblies in the 1-1/4 to 2 inch size range. These assemblies are commonly found in commercial and light industrial plumbing systems where backflow protection is required by local code. Replacement of internal check components, including the check seat, is standard practice during annual testing and repair certification of backflow devices.
