It was a -25F day and I my tub dropped 6 inches of water. This was a fast order and a quick fix. Did exactly what I needed on that ridiculously cold day. Hot tub is fixed!

The “O-ring” type seals were a little too large and didn’t stay in the groove too well but it worked great.

Perfect fit foe my Freeflow Sport model. Much easier to install than I had anticipated. I did not discover your instructions on where to put the gasket until after I had installed it

We live far from any area that has a spa dealership, so ordering online is the quickest way to get a needed item for repairs. They were the right size, they’re made of good quality plastic and they worked.
