39010200 Tank Clamp O-Ring

Great gasket. Old one was stretched out. This fit perfectly and made tank reassembly a snap.

This o-ring was a perfect fit for a replacement on my pentair DE filter. I added a little o-ring lube and it sealed right up. Quality seems no different than the original. Easy installation and overall good value.

Fit perfectly as advertised.

I bought this to replace the O-Ring on our Pentair pool filter. The old O-Ring had deteriorated in the Arizona sun and I could not seal the filter properly using it. The Pentair replacement O-Ring was $60 so this looked like it was worth at least a try. It arrived and I replaced the old O-Ring when I replaced the filters and used some O-Ring Lubricant that I also bought from Amazon, and the filter top seated properly with no leaks. While I can not (yet) vouch for how long this O-Ring will last it does seem to have done the job, and at a much lower cost than the official Pentair version.

Fast delivery and the right part.

It worked perfectly.

Does a good job, but you need to check on it yearly and make sure you install the product properly

Fit well
