I never look forward to replacing the rubber exhaust hangers / o rings. I use a piece of copper fuel tubing bent to shape as a puller to spend around an hour using up to 3 limbs grunting these in to place.

It looks like only Triumph used these on their cars. Has anyone found anything different that works well?

I use a hook pick tool, lots on ebay, something like these, but very easy to make your own

I use one of these:

They're made for loosening radiator hoses, but are good for rubber exhaust hangers too!

Maybe my bad. I was asking if anyone’s tried an alternative to the original O rings

ring fits.I'm sure I have aftermarket O rings as my muffler sat sideways and the tube coming out the back had Thrush muffled dual chrome tips (which was quite heavy). When that muffler burned through I put on an SS Magnaflow that was the same size and had the tips welded on. That lasted a few years until my 3,000 mile trip down to Santa Maria it (the tips) broke off and started dragging on the road south of Monterey on #1, pulled over ripped them off and left them on the side of the road. They were pretty much done. Car had a more guttural sound but still not bothersome on extended highway driving. Use whatever size fits.

Quite a few manufacturers used rubber hanger "O" rings, be worth calling in at your local exhaust place and asking what they have. I get mine from Robsport and they seem to last a couple of years so not too bad.

I get about 18 to 24 months before the O rings from the usual suppliers start to stretch and degrade.

Has anyone tried using something similar to these which provide resistance to both upward and downward movement?

I have these on my Sunbeam Lotus and they do the job well

I think I may have tried some like these as I had them lying around (used on Saab 9000's) but could not stretch them on (IIRC). There is somewhere which does poly 'O' rings which are said to last better but I can't find the link now.

Yes, they may work well once in position.

Working them in to position would be a different matter.
