I would like to replace my below the water line through-hull fittings. Currently the ones in there are plastic or nylon. Of course, I want to avoid galvanic corrosion. I came across these on eBay. https://www.ebay.com/itm/3-4-Aluminum-Bilge-Fitting-Silver-57-4012-/121550475481?_trksid=p2141725.m3641.l6368 Anyone try them? Do you know of a source for additional sizes?
