I am putting together a brass gas tank that is 1 1/2 inches in diameter. I would like to make one end out of glass. I am wondering what would be the best way to glue the glass to a brass ring that would be soldered to the tank end. I was thinking of silicone, but I don't know if it would hold up to the gasoline.
Any one have any experience with this?
As has been intimated by others, in my experience silicone doesn’t hold up well to gasoline/petrol - certainly the silicone tubing used for glow engines becomes very brittle when in contact with gasoline and fails quickly and the same appears to be true for silicone sealants (and your design would require something able to withstand constant immersion). There may be variants designed for full time contact with gasoline but I’m not aware of them and would go with an o ring, JB weld or other epoxy to make the seal.
Good luck! Nick
