right if you go to page 117 of the ap inspiration manual it states and i quote

"LUBRICATION. it is essential when lubricating seals or o rings on the rebreather and oxygen valves that oxygen compatible grease is used. recommended greases include fomblin rt15,halocarbon 25-5s grease and oxygenoex ff250

ok right thats fine, so why does it come with the seals and o rings covered with silicone grease?

should you use silicone on the o rings or not. i realise that the o2 feed pipe that goes into the top of the scrubber should have some o2 lube on the o ring and a little bit on the thread of the first stage.

and where is the place to buy some o2 lube
