No - the seal is the one that goes between the end of the cannister and
the end cap.
>2) Condensation in the breathing loop into the canister?
No, since the only function of the end cap is to allow you to
empty/refill the cannister, and the breathing bag conections are on the
main body.
>3) Water outside the breathing loop (Ocean) into the breathing loop/canister?
Yep! If this seal is not checked properly each time the cannister is
opened, or if the cap is tightened on too tight causing the seal to
extrude, or if you do not put it together correctly and do the post-
assembly/pre-dive checks properly. Incidentally I picked up something
about cannister distortion somewhere along the lines. The only way that
this can occur is if the screw that retains the end cap is tightened up
too tight. The springs on the gauze filter are not strong enough to
cause any distortion.
>4) Gas to bypass the absorbent?
No, since the inlet and exit from the cannister are on the main body of
(see paricularly bad drawing!)
