The Cessna 120-140 Association Forum

Hi All,

I have the tank out of my metalized wing to make repairs. I want to replace the rubber between the strap and the tank. McMaster Carr has 5 different hardness (durometer). Any suggestions what I want to use?

30A (Soft), 40A (Medium Soft), 50A (Medium), 60A (Medium Hard), 70A (Hard)

Thanks for your suggestions.

Dave

Just pick one. Rubber is better than felt. The average is 50 so that might be the best one.

Thanks Randy

I'd try 50 also. Duro 30 is very soft; felt isn't really that soft at all. You want it more for abrasion protection than cushioning.
