Title: exhaust hanger rubber
Post by: Daffer on May 06, 2025, 12:10:08 PM
Im in the process of replacing my exhaust system as its rusted away, after getting a new down pipe to the muffler and new muffler I wanted to get the brackets all rust free my question is the exhaust hanger for the muffler on my 1950 Cadillac has the rubber all stiff, what the best replacement material? I found EPDM rubber from homedepo that sounds like it can work based off what Ive read online it says its heat resistant, maybe someone on here has used it and can verify that info? but any suggestions id also love to hear.

Joshua,

Probably not what you wanted to hear but, the "rubber" part of the hanger is really made from a portion of an old tire carcass and it is riveted to the metal portion of the hanger.

If you want to be OEM then go to a tire replacement place, and buy a blow out tire for cheap and saws-all a chunk out of the side wall and drill your own holes.
Buy rivets and beat them into place - unless you have a press.
Lot's of work and running around, I know.
But what is it worth to you to do it right.

Or, find a place that has old mud flaps from an 18 wheelers and do the same thing - because they too have cord built into their flaps.

Have fun.

Conveyor belt rubber. Or fabric reinforced rubber. I bought some off of amazon. Made it easier to find the thickness I wanted.

I bought a piece from Waldron's Exhaust. Same material as original.

I have used the sidewall of an old tire with good results.  Didn't bother with rivets. Nut, bolt and washers works well too.

thank you for that suggestion!! would this also work since its a considerable bit cheaper only difference is there's no "cloth insert" is that necessary ?

I think the cloth is important. It stabilizes the material.

I would go to a local shop that sells conveyor belting.  Motion Industries or Applied Industrial provide belt material around where I am.  They cut belt all the time and end up with remnants that they just throw away.  You could ask for a small remnant and they would likely give it to you at no cost.

Note: conveyor belt for aggregate conveyors will have fabric and will be plenty strong to hold your exhaust.  Just have a fresh blade in your razor knife to cut it.

Good luck!
Joe

The material is called Rubber Insertion, and is available in sheets of differing thicknesses to suit your needs.

I managed to get myself a length of old Conveyor Belting which will last me a number of lifetimes.

Whilst it is not being used as exhaust hangers, I lay it on the floor where I stand at my various benches, so I have something "softer" to stand on instead of hard Concrete.   My lengths are 3 feet wide, and 1/2" thick, and thinner where it is worn, so I have plenty to select for each requirement.

 Like others have said ,it was used tire rubber when new. I have found cutting it with a  electric reciprocating  saw with a metal cutting blade is very easy. It doesn't work well if you get into steel belts  or steel in the bead. So I generally cut up garden tractor tires. Where I live the garbage company will not take old tires. They will take tire pieces.
