I need to fabricate some rubber parts for a custom air intake system

connect various pieces of steel tubing together with an air tight seal

hose clamp without tearing. I'm thinking a shore A hardess of about 40
should be adequate. It's a non-production, hobbyist application.
Temperatures will unlikely reach over 350F. The end result will be
something similar to a coupler used for turbo/intercooler plumbing, but
that's not my intended use.

What a coincidence!

I used 80 shore polyurethane and stretchable polyester fabric. The elbow is
in my car now and sees 20 lb of boost. I got my polyurethane locally and
polyester fabric at local fabric store. I believe the you can order
polyurethane from www.mcmaster.com
