Pentair Nautilus Filter Tank O-Ring 18" 0-184 152127

Wrong size

Great O-ring at a great price - but shipping is slow from the company. It's a tad bit large for my Nautilus filter requiring a bit of 'tapping' when I install the retaining ring -- but it works great thereafter and a heck of a lot cheaper than purchasing essentially the same thing from the local pool supply store.

As others have noted the diameter is a bit large making it cumbersome to install, but it does work. Putting it in the freezer and lots of silicone grease help somewhat to keep it in place while assembling the top half of the tank.

This is a little thicker than my original, which makes it difficult to close up and seal my filter. Once I can get the filter back together, it does its job.

The Pentair Nautilus Filter Tank O-Ring is 19" in diameter not 18" 0-184 152127. This does not fit an NS 24 Nautilus DE Filter Tank. Ordered this June 24, 2020 but did not close my pool till Sept 11 when I disassemble my Nautilus NS 24 DE Filter to see if the "O' ring fit and it did not!!! now i am stuck with !9" "O" ring that is past the return window!!!

It was actually a bit bigger than 18", so you have to push the slack in all around the filter. Also, I expected it to have a rectangular cross section like the original one, not round.

O-ring for D.E. filters... it fits ... it seals... seems as sturdy as the previous one... no issues... no regrets. Fast shipping and good communication... not much else to be said

After getting 4 different, wrong o rings at the local Pool Warehouse and Leslies Pools, I ordered this one on line. It was the correct one. The others were either too fat or too skinny. I was told that the correct gasket for my filter was flat, not round. Anyhoo, this part was the correct size, fit perfectly, was sent quickly and was a good value.
