A while back I purchased a heater gasket set from one of our preferred vendors and I now see that it's more of a foam rubber material. I don't think this stuff will hold up to the test of time...........
Has anyone purchased a true rubber set of these gaskets? If so, where did you get them? I checked Steele Rubber Company's online product catalog and didn't find them. I may just get some 1/8" sheet rubber and cut my own.

Those hole punch sets from harborF work great for that.
Give me ambiguity
or give me something else

When it compresses, it will fill any gaps caused by differences between the flange and the inner cowl. It should last just fine since it isn't exposed to the outside elements.
I would use 3M weatherstrip adhesive to glue it to the heater flange and leave the other side of the gasket clean in case you ever need to remove the heater later.

I'll use the pre-made foam gasket for the inner cowl and cut a round rubber one for the motor through the fire wall............
Good idea on the clean gasket side too! | | |
