I don't do it nearly often enough, but I dismantled my bulkhead and the o-rings are in pretty terrible shape. Any recommendations on where to get replacements?
Tim,
Where did you get the fittings? The source ought to have them, or tell you the size. If you wanted 25 or 50 each, and knowing the size, McMaster is an option.
I don't know of other options for just a few, other than Local/online HBS.
