What is the purpose of a crush washer?

A crush washer is designed to deform slightly when tightened, creating a seal between two mating surfaces. For -6 AN fittings, it helps prevent fuel from leaking out of the connection.

Can I reuse a crush washer?

It is generally recommended to use a new crush washer every time you disconnect and reconnect a fitting. Reusing a crushed washer may result in a poor seal and potential leaks.

What are these washers made of?

These DeatschWerks crush washers are made from aluminum. This material is chosen because it is softer than the fitting it seals against, allowing it to crush and form a tight seal.
