These fit my Solana TX spa nicely. I kept the original o-rings in place and added a single gasket to each compression joint. Added some silicone grease and have not had any leaks.

They work great, not the easiest thing to replace because you need to pull the pump hose off, but once in, no leaking!

Very high quality. Feels like silicone. I should have taken my spa apart before I ordered. My old heater gasket was ribbed on one side with a groove in the union to accept the rib. This gasket is flat on both sides for unions that are flat on both sides. This company sells both types of gaskets. If I had to do it again, I would get the correct gasket. But it works fine anyway. Five stars for sure. Also, heater gaskets and pump O-rings are two completely different things. I don't know why they don't use the same union for both, but they don't.

Ordered these o-rings to rebuild two pump casings for my spa. They arrived when stated and well packaged. They matched up exactly with the old old rings and were installed with no problems. I highly recommend this o-ring for your next upgrade.
