joint between the pump seal plate and housing.\n    Replacing this gasket helps stop external water leaks and helps prevent air from being drawn into the pump (which can affect priming and performance).\n  \u003c\/p\u003e\n\n  \u003ch3\u003eCommon Applications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eSeal plate-to-housing sealing surface on select Pentair and Sta-Rite pump
