🔒 Enhanced Sealing Rubber Ring for Marine Color Sunsun Canister Filter HW302 402A/B 702A/B Review

It's been a few months since I replaced my leaky fish filter ring with this and it has worked well. Worth the money spent. Use this if your SunSun filter is leaking at the top.

Arrived very quickly. Bought because my Sunsun canister filter was leaking water from all the caps. In less than a minute I was able to remove the old o-ring and replace it with a new one. No leaks, filter works as it should!

Works as it should. My 702B started leaking one day so I replaced it with this one and before installing I compared the thickness to the old one and it's definitely a bit thicker. The canister now works leak free, I hope it lasts another 5 years.

You were perfect the buyer was great but the product didn't fit. It's my fault. I can't remember exactly which one I got, but I do know the ring on mine was bigger. Thank you for sending it to me. I'm sorry I wasn't working

Looks like it will match my filter. I bought it to have on hand in case the original breaks or runs out. And I plan to replace the old o-ring when the filter has lasted a year. Next time I clean the filter I'll try it and see if it fits. To update! Fits my 304B perfectly. The old seal was about 1 year old.

I have had a Sunsun HW-302 canister filter for 2 years now. i have a river The original plastic O-ring looks fine but is leaking. Changed and the leaks stopped. I will definitely order more. If you have a 2 year old canister, make sure you check for leaks when you change the filter. Water leakage and damage is a pain! Updated 8/4/2020, this replacement ring only lasted 14 months. So plan accordingly
