Product Overview

The Pentair 357100Z is the genuine black Buna seal plate gasket for Pentair WhisperFlo and IntelliFlo pool pumps. It seals the seal plate against the pump body so water stays inside the wet end.

This is the current black gasket used on pumps built from February 2008 to present. Replace it any time the pump is opened for a shaft seal or impeller job.
