Does anyone know where I can source one? I tried several times to get in touch with Larry Denhan, but I have never received a response. I went to a commercial supplier, and received a #14, but high durometer. It transmitted a ton of noise to the table. Any thoughts?
Thanks, Tom

You should be able to pick up what sounds like an o-ring at most automotive jobbers or hydraulic shops. Home depot list some but don't list the hardness. If I remember correctly. The hard ones are about 90 durometer. The standard nitrile ones are around 70 or 75 and the silicone ones (often yellow)are around 60. If it was black it was probably the standard one.

You are correct. The black ones are around 80 to 90 durometer. These pass an incredible amount of rumble. Finding something softer than yellow would be the ticket

Tell me the diameter and I'll look for you.

Actually the black ones are available in a couple of durometer's. A decent auto parts store or hydraulic shop will have both 70 and 90. If the first one you tried was a 90, try a 70 next. It will be considerably softer than a 90 and easy to find. If they have silicone ones as well try one of those. The link below gives you an idea of what's available. But buying 1 or 2 may be problematic. But o rings are cheap so a pack of 10 will still be reasonable. Ideally you can find a quality brand like Parker.
