I own, and have at times used these 2, O2 clean Mares Proton V16 first stage regulators in warm to chilly water in the mid 40's with no real issues on deco bottles of freeze-ups. Not being a Pro Scuba Gear Tech, I was wondering the process for Environmentally Sealing these 2 first stages for use in colder waters. I am assuming it is going to be a 'wet' fill such as Christo-Lube-?? Is there any printed materials that might walk me threw this process? Thanks for any input.
