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 DOW 111 lubricant on the O-ring every time you replace the filters.  Dow 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 tube or 5.3 oz tube.

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 :-)

Is this reefsafe for use in reactor canisters or even skimmer necks (for my Bubble Kind that screws in)?

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!
