I am restoring an old motorcycle and one of the parts I cannot find is the rubber boot that connects the carburetor to the engine. I have the original brittle part that I can use to make the mold.
Do you have a urethane that will withstand contact with gasoline?
Thanks

Testing has been done with Alumilite Regular which is stable in gasoline ... however not many of the other products have been tested with gasoline. Have you ever used the FLEX, if you have some scrap pieces I would submerse the cured piece in gasoline for a few days to a week, then pull it out and see if it has softened or tacky or if you see any other differences in the soaked piece.
If you don't have any scraps Tedh98, let me know I would be happy to get some cured pieces to you for test. Have a great day!
Regards,
Carol

I don't have any Flex, but would be happy to do the testing. How should I get a hold of you to get some cured pieces?
Thanks

Alumilite got me introduced to making parts 6 years ago. I needed a intake boot for a Kawasaki Tecate 3 wheeler (fits between carburetor and jug of motor. I have worn out several molds making them for friends/resale. Literally a thousand made give or take and have never had a issue with air/fuel mix deteriorate the flex 80 I use to make them. I now pressure cure @ 55lbs. to make a very good part even better. Doing another run of them right now.
john P.S. ~ thanks Alumilite crew, you all ROCK IMO !

Here is photo bucket link to what my flex 80 intakes look like basically right from Alumiltes tin cure HS2 silicone mold rubber (you will need to use tin cure mold rubber to make mold from your old intake boot, platinum mold material will be contaminated for the rubbers used from back in the day) Just a light trimming done. The left over from my 2 part pour mold will be cut off with band saw and the long thin piece is from vent hole that will get snapped off. I think you may get all my photo bucket pictures (sorry)but there only 2 of the intake boot I just demolded this morning. s1122.photobucket.com/user/jeswinehart/media/1.jpg.html?filters[user]=123606882&filters[recent]=1&sort=1&o=1
