I tried this. It didn't work, at all. I had a few sizes of nitrile O-rings I use for another purpose (micro lathe drive belts) and tried a range, the BS336 as mentioned worked perfectly. It may perhaps work for other brands of tape unit if the hub pinch clamp arrangement is the same diameter but that is for someone else to try. Steve.
