Who Sells Large Silicone Gaskets?

Who sells large (1.25" water heater element size) food grade silicone gaskets?

Bargain Fittings sells o-rings, but no gaskets that size.

I have found sheets of gasket material, but no gaskets that size.

I cut one from a length of silicone tubing I had. Works like a charm and was quite inexpensive.

That's pretty neat.



Food grade silicone gaskets start at a couple of bucks, that tubing is about $2.35 a foot. Bet I can make a TON of gaskets from a foot of it.

I have extra material... prob 3/16th thick. If you want, PM me and Ill send you some...

McMaster Carr

Grainger but in packs of 10, still decent price though

mcmaster.com

bed bath and beyond sells all kinds of silicone cookie sheets, cup cake molds etc that can be cut into gaskets.

Thanks, I have a few feet of the tubing. I cut a piece to try Sunday, in fact.

Sorry to bring back and old thread....but how can you cut a clean hole in a silicone square like in the picture above ?

I need to make one myself but I'm unsure how to proceed

I have a plotter/cutter that can do it, if it's under 0.08" thick.

You'd have to pay shipping both ways, but I'd be willing to give it a try. No guarantees, of course.

I made a punch by sharpening one end of a piece of copper pipe with my disc sander.

Xacto knife and a drafting compass.

I just traced a circle and cut it with an x-acto knife. Made it slightly smaller than the hole and stretched it over the threads on the heating element.

You know that good old silicone aquarium sealant cures to something that is silicone for all intents and purposes. Why not just use that?

I do, but would prefer to use a gasket.
