Sta-Rite C20-86 Gasket
The Sta-Rite C20-86 is a replacement gasket for Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps, seated between two machined surfaces inside the pump to seal against water and, on the suction side, against air that would otherwise break the pump's prime.
Gaskets should be replaced any time the joint they seal is opened, even if the old one looks intact, since the compression set that makes a gasket seal in the first place does not fully reverse once the bolts are loosened. Clean both mating surfaces of old gasket material before installing the new one.

Frequently Asked Questions
Q: Will this fit a different pump in the same series?
Only if the joint dimensions match. Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps use different gasket sizes across the family, so match the exact part number.
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.
Q: Can I reuse the old gasket if it still looks fine?
It is not recommended. A gasket takes a permanent compression set the first time it is torqued down, so a reused gasket is far more likely to weep than a new one, even if it looks undamaged.
