20 gaskets for 10k 50A pipe flanges. There are scratches and dirt from storage. Packaging will be simple. Other sizes are also available. The edges of the gaskets are sewn with Teflon sheet and thread. I used this for the first time. It's much easier to handle than the Teflon sand I've used before.
