Part Details: Check Valves #491325-V & 491328

These heavy-duty check valves are used in Lafferty pressure washer foamers and sprayers, boosted and high water pressure systems, or when stainless steel and maximum durability are required.

Check valves may become clogged with physical debris or chemical buildup. The Viton valve seat and spring may also need to be replaced due to chemical exposure.

The spring, valve, and valve seat are held inside a threaded 2-part body that can be separated using a vice and/or pliers. Caution: internal components are spring-loaded.
