Hi Stuart (or Scott, I'm not sure which), Thanks for your comments. Of course I'm aware of brand names being used for generic items i.e. IBM cards, Aspirin, Kleenex, and Xerox copies. But in this specific case, I believe it is not wise to refer to O2 compatible lube (such as Crist-O-Lube) as "Silicone" or your term "sil grease." I can easily imagine some inexperienced diver, after hearing about using "silicone" with oxygen systems, going out and using some G.E. Silicone grease on a deco reg for 100% oxygen. And I hope you agree that this really is dangerous. Take care and safe diving, Scott In a message dated 8/11/00 7:13:28 AM, stuart.morrison@sw*.co*.uk* writes: << Hi Jim, like you I do not own one single reg which has had an O2 kit. Five years of O2 and they still work the same. I'm still using an original first run Apeks T40 (before they added the 'X' as a marketing gimmick to make it the TX40) with O2 with all original parts. It has been cleaned and regreased many times and there has been no noticeable degradation of any part except the mouthpiece which I bit through when some fool knocked me off a deco stop. I don't know if it makes a difference but I flush it through with some air after every dive. O2 kits and, more so, branded nitrox regs strike me as a con. > I believe you'll find that any O2 compatible lube is not a > silicone and > surely not silicon. It's like not all vacuum cleaners are made by Hoover, but over here a vacuum cleaner is still called a hoover regardless. That slimey stuff you lube regs with is always called sil grease regardless of what's in it, it's just a general term, not a specific. Bloody hell, jetfins have neither jets nor fins on them and no-one complains :) S In a message dated 8/11/00 4:47:28 AM, ScottBonis@ao*.co* writes: Hi Jim, I believe you'll find that any O2 compatible lube is not a silicone and surely not silicon.

"02 Kit" is nothing but a scam. I have been using no special prep regs on 100% 02 for the last 5 years, as have many of my dive buddies. No explosions or even failures. Sounds like shop #4 would be the one to deal with.
