Perfect fit for my FREE FLOW HOT TUB. I used a tiny bit of white silicone because that's what the old one had. It did help to have another person there to help hold it on place when installing....since you cannot simply reach around to the other side. It came with a New o ring for the sensor which is nice. Stopped my leak and WORKED out great.

I purchased this part because the old one had basically disintegrated and cracked after 20+ years, and a leak had developed. The only thing missing with this part is installation instructions. It's not that it's difficult to install, but some mention that you do use clear silicone when installing this piece and guidance on EXACTLY where to apply the silicone during the installation would be helpful. The only reason I knew to use silicone was that I had to peel it off the old one. The repair was successful and the leak is fixed.
