Bill, use them if you have them. I have found them unnecessary. However, if you can suggest a good source for the tiny o-rings in the hp spools that are more durable, I WILL replace those.These tend to mush out + Also, getting the correct durometer o-rings for each application is well beyond the farm animal stupidity that is the trademark of most dive shop savants. In addition, Chief, on your oxygen cleaning stuff, everything needs to be clean and free of hydrocarbons, and we all know this. What the savants don't know, and why we see these problems, is that you also must have decent valves, not nickelrocketry like comes with most "kits", and these need to be operated properly, a big problem when you are talking divers or dive shop monkees. On another subject, Bill, only a complete moron would have a filter in a regulator - that is begging for trouble, and you just showed three good reasons why. What do es one expect to be in his scuba tank that requires a filter which just disintegrates and ruins the regulator or causes a fire when operated by a mongoloid dive shop mutant? The most life-supporting use of compressed air has no filters, but then as the Army found out in Carter's botched Iraninan hostage rescue attempt - you don't operate in sand. Next time you get on a 747, make sure they have filters over the four air compressors you are beting your life on, and make sure they have oxygen cleaned those babies. I have enough to worry about, but then I know where my gas comes from, and no idiots operate my equipment. Keep in mind you are looking at only part of the problem, and ignoring the rest, which is how the dive industry gets ( unnecessary) business. This "cleaning" then becomes a mysterious secret operation requiring at least two major credit cards with a personal financial statement required to get in line for the unobtanium o-rings available only in a complete kit specially collected by the same morons who can't make the regulator right in the first place, available to you only if you allkow the dive shop Quasimoto to intall them. As Hyperski says, "tanks, but no tanks". - G Bill (aquadart) Bott wrote: > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > George, > > I hear the sarcasum.
