Subject: Re: G-250 rebuild
John, I think they sell to anyone who takes the ( free ) clinic. This
prevents the kind of monkery that surfaces like putting the 200 seat in
the 250 reg - a popular piece of stupidty that went on for a while which
causes the poppet to slip by and fail the reg in the off position ( the
tubes in the 190 ( or metal ) version are not the same size as the 250
version , a subtle difference.

Most of what causes the 250 seat to wear improperly involves improper
installation adjustment, and use. The other common problem is letting
the reg dry out too much which causes the orifice o-ring to dry up and
let gas hiss by ( not the seat at all).

The 250 is the premier reg for decompression - it keeps the WOB to a
minimum on what amounts to the longest and highest ppo2 point in the
dive.
