Rubber gasket...or, if the cap is round, rubber o-ring, which you can
find if you google Beckson (they make inspection port retrofit kits).
Call 'em and give 'em the size. O-rings should be replaced about every
5 years or so.


Thanks, Peggie. They weren't very encouraging when I called, but perhaps if
I pull the cap and take it up to their location they can match the O-ring.

I may know of another source...What's the diameter of the cap?
