Should I replace the gasket whenever the parts are opened?
Yes. A compressed gasket rarely reseals reliably, so fit a new one whenever the joint is taken apart.
How do I confirm it fits my equipment?
Match one of the OEM part numbers listed on this page against your equipment's parts list or the number on the old part, and compare the shape and hole pattern with the old gasket.

Let customers speak for us
Super fast shipping and reliable product !
I accidentally broke the original **** by tightening it too much. This was a perfect fit and works 100%. Fast delivery too!
Swapped out broken heater (lasted about 6 years) for this one. The instructions are for the electronics, not for the plumbing. You must get everything perfectly aligned or the plumbing may leak. I needed to loosen the electronics box to get the plumbing perfectly aligned. I have hot water again.
Great prices, fast shipping, great products
Haven't received yet but I'm sure it'll be great
Ordered on Saturday and we're delivered by Tuesday! Great products and great prices!
PST pool supplies are great to work with. I was having trouble finding this heat exchanger . Everywhere I looked, it was out of stock or back ordered. I contacted the manufacturer about buying the heat exchanger. They told me I couldn't buy it because I wasn't a dealer. If I was a dealer, they would be able to take the order. And make one, it would take 5 to 8 weeks. I contacted PST they put my order in and I received it in about six weeks. Fantastic people to work with. Thanks Tim
As described original equipment, thanks
Easy. Came quickly. Wish the shipping was free. I paid extra for insured shipping and it wasn’t signature required. Simply left in my mailbox.
My hot tub stopped giving a signal to trigger the heating core. I had to replace a whole motherboard and they had the perfect product and with a couple of screws. It went right right in and worked perfectly.
Worked perfectly to get our pool filter motor back up and running.
Great price and it was the exact fit for my TM26 Filter.
Easy to install it took 20-25 minutes and it was back up and running with no issues!
Work perfect
Same pump and motor I needed for my pool setup and would’ve been great if I didn’t have to tear apart the new one to install old part. Best price I found anywhere too.
