[QUOTE="Kevin Thomas, post: 502673, member: 15748"] No, they're not conservative, they're industry standard. You shouldn't be seeing too muchin the way of CUP these days, since the industry is switching over to PSI or BAR figures. There's problems in judging pressure with copper units, and the more modern PSi figures are much more accurate. There is, incidentally, no conversion for CUP to PSI. They don't have a linear relationship to one another, and shouldn't be confused. As to the older CUP numbers (and PSI, too, for that matter), each cartridge will have its own standard. Which cartridge are you looking for? [/QUOTE]
