I am clarifying my blog about the use of silicone lubricants on the O2ptima breathing loop because I received some questions that made me realize I needed to give you more information.
I posted the first one out of frustration with what I had seen on units coming in for annual service. We were cleaning enough Christo-Lube from the head and loops to lubricate over 100 regulators. It was simply unreal. One unit could not pass the negative canister test due to the debris attracted to the seals from excess lubricant. You can use Fluorosilicone lubricant commonly known as food grade silicone on the head seals without problem. If you use non food grade silicone on the silicone seals of the head it could lead to the o-rings swelling because it can be absorbed by silicone o-rings. So use either food grade silicone lubricant on the loop or Tribolube 71, which is an inert lubricant.
If you can see the lubricant you have used too much and it can actually prevent the seals from sealing properly because the excess will attract debris. The most common debris found is hair strands which will prevent a good seal.
Remember more is not better when you are lubricating the seals on your breathing loop. If you have too much lubricant and it gets in the loop, guess where it goes. It’s your breathing loop.
