I traded a guy on the board an interface for a US divers conshelf 1st and service kit (luckily) recently. I just got it in the mail the other day and anxiously started breaking it down to see what kind of shape it was in. I'll post a pic tommorrow, but I'll go ahead and tell you that it was totally encrusted with sand and gunk. I'm not sure if it was useable before but it looked pretty bad to me. No sand internally but I'll say this since I love my MK20 and I know how much Mike hates pistons... The Conshelf (diaphragm) reg's "environmental area" just like the pistons Mike mentioned was full of crap. This did have an effect on the conshelf because the crap was covering the diaphragm itself as well as the main spring. The conshelf is known as a near bullet proof reg and its just as open, if not more so, than my mk20 to intrusion. In the conshelf there's only a narrow slot for stuff to drain and this buildup gets right into the threads and makes (made) it a real pain to get apart. I took several pictures and I'll actually just post them on my site tommorrow with a link here.
As a side note...
on the "Blue" color of the orings on the piston, it is not because of contact with salt water. (by the way, salt water leaves green residue - like on the filter (very rare to see green on the piston orings). Gray on the filter from oils and contaminents, red(rust color) from moisture - bad air sources.)
Anyway, the blue you saw was the discoloration from the Christolube used to lubricate those areas. Ive seent hat quite common along with PINK colors as well. I haven't been told if it's a 'bleeding' of color from the oring into the surrounding normal white-ish color of the Christolube or not. I wouldn't have normally thought it be the case as Scubapro uses EDPM orings which are typically much better quality than most of the orings out there. I would think the harder dirometer of materials wouldn't bleed color as easily, but I'm not sure of the reaction of compounds from the Christolube? Christomlube is a VERY stable compound - (ie read the material spec sheets from it.)
I've seen that 'Blue' tons of times and it has nothing to do saltwater. Many of the regs have never seen saltwater.
