is there any grease that doesnt react with rubber?
James, there's rubber-friendly stuff called "Molycoat" which the instro's used where I used to work, and as well, there may be some food-grade grease which doesn't deteriorate rubber, although it might not be available in the smallish quantity you're after. The Molycoat is toothpaste tube size.
