Pentair Heater Gasket Tube Seal 070951

I bought it for my spa and it works perfectly no more leaks I can use my spa

Great place to order form I would buy from them again and the shipping was fast.

One day, my hot tub decided to squirt out of the side and create a giant ice sculpture, so I drained the heater, pump, and filter. Turns out that my orings had failed. After removing the header, I saw that the old ones were squashed and deformed from 4 years of service. I put these new ones in on the one (leaky) side and kept fresh ones in case the other end ever leaks. ''
Tighten AS HARD AS YOU CAN so you only put these on once. ' 'Great price, even though it is just rubber.
