Are Injector Copper O-Rings Reusable or should they be replaced every time an injector is removed?

Thanks!

I wouldnt reuse them as copper distorts once pressure is put on them, essentially flattening them.

They are cheap enough to just use new ones.

I have reused them... I think Pat mentioned he uses some fine sand paper to clean them up. If they look good run them. They aren't much money either.

The o-rings just keep dirt from packing around injector body and the cylinder head. I use Cat silicone o-rings, much cheaper for me.

I've reused them plenty of times without a problem. I guess I've been lucky which I find odd since I usually have crappy luck.
