Sta-Rite N20-35 Gasket
Sta-Rite specifies the N20-35 gasket at the joint it seals. A pump that weeps at a seam, or that loses prime overnight, often just needs this gasket rather than any deeper repair.
Over-tightening the bolts around a gasket will not fix a leak and can crack the housing it is meant to protect; if a properly torqued joint still weeps, replace the gasket rather than continuing to tighten it.

Frequently Asked Questions
Q: Do I need any sealant with this gasket?
No. Sta-Rite gaskets in this class are designed to seal on their own when properly torqued; adding sealant is not necessary and can make future disassembly harder.
Q: Will this fit a different pump in the same series?
Match the exact part number on the old gasket rather than assuming similar-looking pumps share the same size.
Q: How do I remove the old gasket material?
Scrape both mating surfaces clean with a plastic or soft-metal scraper rather than sandpaper or a wire wheel, which can gouge a sealing surface and create a new leak path.
Q: How tight should the bolts be around this gasket?
Torque evenly in a criss-cross pattern to the housing manufacturer's spec rather than over-tightening, which can crack the housing without improving the seal.
