O-Ring for 10" Reverse Osmosis Canisters

SKU: 200904


  • slow leak By Oscar on 11/16/2013

    I have a very high pressure 95psi water line. While these o-rings seem to work okay when new, by the time you replace the filter cartridges you will notice that they have become bit squared. I have measured these to be 85mm ID by 4mm CS. My solution is a #340 standard, 70 duro, FDA approved, EPDM o-rings that I bought from an online o-ring store. The size is slightly bigger than this o-ring but works perfectly, 3 3/8"ID by 3/16"CS. Now I don't have to over tighten to get a perfect seal. FYI, I bought my 5 stage plus from BRS in July 2012 so I'm not sure if I have the old model.
  • Too small By Ron on 9/23/2013

    I had to return the O-rings as they were not the correct size. The O-rings do not fit the older RO canisters
  • The Fix That I Needed--Pronto By Old Salt on 4/4/2013

    For some reason, my BRS reactor came without an o ring. BRS sent one of these out to me at no charge. Got it within two days. Now the reactor is going strong. The product is fine, but the customer service is exceptional.
  • Perfect By Steven on 2/14/2013

    I ended up ordering these hoping that they would fit a different manufacturers canister but they were just a hair smaller in diameter.

    After getting the sediment canister to seal I still had a leak on the carbon stage and the new o-ring didn't do the trick.

    Sent BRS and email and they offered to send me an older style o-ring at no charge. THIS IS HOW CUSTOMER SERVICE SHOULD BE!!!!

    Even though I only spent a few dollars they were willing to go above and beyond to help me get my RO working again!
  • Good to have these just in case. By Oscar on 8/6/2012

    Good quality. Not that I expect my existing ones to fail but it's good to have a few spares for peace of mind.
