Sta-Rite C43-46 Gasket
This is the C43-46 gasket for Sta-Rite Dyna-Glas/Dyna-Max Series in-ground pool and spa pumps. It is a wear item that hardens, compresses permanently, or tears a little more every time the pump is opened for service, so a gasket that has already been reused once or twice is a common source of a weeping leak.
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: 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.
Q: My pump loses its prime overnight. Could this gasket be the cause?
Yes, a gasket leak on the suction side lets air into the pump between uses even though it may not drip visibly while the pump is running. It is one of the first things worth checking for a lost-prime complaint.
