Why does BRS recommend this?

Have you ever had a canister get stuck and not want to come off when you are replacing filters on your RODI system?  The secret is putting a slight amount of Molykote 111 lubricant on the O-ring every time you replace the filters.  DuPont Molykote 111 O-ring lubricant is used to prevent the O-rings in RO canisters from binding up when tightened and provides a tight seal. We usually have a bottle of sitting with our replacement filters.


  • Available in Single Use packet or 5.3 oz tube.

Product Questions

Is this reefsafe for use in reactor canisters or even skimmer necks (for my Bubble Kind that screws in)?
Question by: Kyle on Apr 14, 2016, 12:06 PM
Great question!
These lubricants are designed for use in drinking water systems are certainly can work in the tank without issue. Feel free to let us know if you have any further questions!

How many uses might one expect to get out of the 5.3 oz package?

Hi Chris,
It depends on the size of your o-rings and how much your applying each use, but for most folks in the hobby its a lifetime supply :-)
