I decided to do an OCI yesterday and was going to re-use the gasket that has rubber in the middle and metal on the outsides but I misplaced it after I took it off, then found it later. So I put an aluminum gasket on it, and it leaked, so I removed it today and put a plastic one on and it no longer leaks. The plastic one didn't take as much torque to tighten the bolt as the aluminum one, which still leaked. Why did that aluminum gasket leak? I was afraid to tighten it any more, afraid I'd strip the threads on the bolt and that's why I instead replaced it with a plastic one.
Is it OK to re-use drain bolt gaskets?
I seem to have reused them many times in the past and it doesn't seem like any of them every leaked.
