A must Have! By Merle on 4/26/2017

I got by without buying this for a couple of cartridge changes and paid the price! Without using this, the O-rings in my 150 gpd RO/DR didn't exactly dry out, but they no longer allowed the canisters to slip by without sticking. This caused undo wear on the O-rings, leaks etc. Ultimately, I had to replace the rings. An unneeded cost had I just bought the Molykote 111 at the start. Buy the 5.3 Oz tube and it will last you a lifetime.

Wish I purchased this lube when I started my tank build a year ago! I Found out O rings do not like dry installations, especially for true union fittings.
A must have for all orings By Ryan on 8/26/2016

I put some of this on my Vertex Zeovit reactor o-ring on the rod that you hand pump everyday - made it 10 TIMES easier. Also plan to use it on any and all oring seals that need frequent removal - skimmer, filter canisters, etc. Good stuff!
Makes all the difference in orings By Al on 4/9/2016

I used to have to reseat the protein skimmer orings as much as 5 times prior to using this -
I can't believe the stores that sold me products with orings did not tell me about this
Works Great By Dedeo on 7/6/2013

My Marineland c360 canister filter was leaking and sending out millions of tiny air bubbles the 4th time is cleaned it. spent hours trying to figure it out. I emailed Marineland and they said I needed to lubricate the big Oring around the lid of canister. I said ''yeah right''. This stuff worked great. No leaking and no bubbles. The only reason I gave it a 4 star rating was because there were no instructions. This product works Great!!!!!!
Feel silly for not ordering before By Travis on 5/7/2012

So I feel a little silly now for all the times I struggled and cursed at struggling to be able to open my RO canisters to change the filters! I should have know better but now that I do hopefully they won't be such a pain to open next time and if they're not I might have to invest in the larger size.
