What is the purpose of an aluminum crush washer?

An aluminum crush washer is used to create a seal between two mating surfaces, typically a fitting and a component like a fuel rail or adapter. The aluminum deforms under pressure, filling any small imperfections and preventing leaks.

Why use aluminum instead of steel for a crush washer?

Aluminum is softer than steel, which allows it to crush and seal more effectively without requiring excessive torque. This makes it ideal for sealing fuel lines where a precise, leak-free connection is essential.

How many crush washers are included in this pack?

This pack contains ten (10) aluminum crush washers, providing multiple units for your project and spares for future use.

About this part

Product Details

When you're working on your fuel system, especially when installing or replacing fuel lines and fittings, getting a solid seal is critical. These DeatschWerks -10 AN aluminum crush washers are designed to help you achieve just that. They're made from aluminum, which is a softer metal than steel, allowing it to deform slightly and create a tight seal against the fitting and the mating surface. This helps prevent fuel leaks, which are not only messy but also a safety hazard.

This pack comes with ten washers, so you'll have spares on hand for future projects or if one gets dropped or damaged during installation. They are specifically sized for -10 AN fittings, a common size in performance fuel systems. Using the correct crush washer ensures that your fuel lines are properly secured and leak-free, letting you focus on your engine's performance.
