When you heat up a piece of copper thats been crushed then toss it in water it will stay expanded.

Problem is when you quench it, it doesn't stay soft and is more brittle. If it air cools it will stay soft. Either way they will likely seal just fine.

You have two options. Toss them and get new ones or lightly sand them and spray them with copper coat. You could even use a dab of engine case sealer on them.
