About This Item
OEM Replacement Washer for Pentair FNS D.E. Filters
The Pentair 195004Z is the OEM replacement polyethylene washer for the FNS series D.E. filter lower pipe assembly. If your FNS filter is showing wear or leakage at the lower pipe connection, this washer is the correct service replacement.
What It Does
This polyethylene washer seats within the FNS lower pipe assembly, providing a sealing interface that maintains proper water flow and pressure integrity within the filter tank. Replacing a worn or deformed washer restores the assembly's sealing performance and prevents bypass of unfiltered water.

Pro Tip
Before ordering, compare the dimensions stamped or printed on your existing washer against the 3" x 2-3/8" specification listed here. FNS filter assemblies were produced across multiple generations, and washer dimensions can vary between model revisions. When the lower pipe assembly is disassembled for service, inspect the lower pipe manifold and any associated O-rings for wear at the same time — replacing worn sealing components together reduces the likelihood of a repeat service visit.
