Sources for deck caps for waste, fuel, and water

Several captains have suggested the following sources for replacements of the stainless caps to the various tanks.¬ Most of¬ the sources below require you to buy the whole fitting.¬ Defender sells just the cap.¬ To me, the chains are dangerous and just beg to have the cap go over the side.

If they are continually stress-loaded (i.e., carry the dinghy all the time on the davits) while used in the tropics or similar climate, they may develop stress corrosion (i.e., cracking) of welded joints. If stress corrosion is evident, his advice is to have a qualified welder re-weld it and, in addition, add a gusset (about 1-inch triangular piece of filler metal) on each side of the broken weld.
