I had this dilemna a couple of months ago. I went to home depot and bought some rubber gasket material and made my own. It cost like $3 or $4. I had 2ea 2" bulkheads and like 3 1" bulkheads that all needed new seals. None of the ones I made have leaked. If I had it to do again I would make my own for sure. That is unless I get rich
