A vital part of fuel cap especially if plane sleeps outside. Inspect and replace as needed to avoid water intrusion. Worked as intended.

These are high quality gaskets. I replace my gaskets every few years to ensure I have a tight seal between my fuel caps and fuel tanks. They fit perfectly on my Cherokee PA-28-180F.
