Tiki Island Pool Express R0586300 Large VITON Collar O-Ring Nature 2 Fusion Replacement

These things do stretch out when the lid is opened and closed several times, so remember to get a few of these, as you'll eventually need to replace each. If you let them sit out for a few days or longer, they will likely return to their original size or close to it, but I haven't tested that yet. I will test it and update the review when I need to replace the one I'm using now.

These fit perfectly, far better fit than the manufacturer's product! Replaced with manufacturers o-ring twice. The fit was terrible and they leaked terribly and was almost impossible to get to seat properly.

WIsh I had ordered sooner. The old tablet side ring had swelled making it hard to screw top back on. Replaced with this one, no leakes and easy to put top on again.

I ordered this replacement O-ring for my leaky one. When I first put it in and sealed it up it leaked 2 to 3 times more than the faulty O-ring. Frustrated I unscrewed it, examined it and saw that it looked very tight. I then took it in my hands and gently, not a ton of force, rolled my hands around the inside trying to stretch it out slightly. It took three attempts, but on the third try, no leaks at all.

So, the diameter was correct, but the ring itself isn't thick enough compared to the original part. Now that I've used it, I can't return it. Guess I'm heading to the pool store tomorrow. I wouldn't recommend.

Fits perfectly on the chlorinator side and the leak stopped immediately.Didn’t even have to crank it down like I was doing before.I may buy another as a backup!

No leaks

Perfect Fit for my Nature 2 Fusion chlorinator. Stopped my leak instantly.
