What is the purpose of a crush washer?

A crush washer is designed to deform slightly when tightened, creating a tight seal between a fitting and a port. This is especially useful when the port doesn't have a groove for an O-ring, or when using fittings with a straight thread.

What size are these crush washers?

These are -8 AN size crush washers. The AN size refers to the standard for fluid fittings in automotive and aerospace applications.

What material are these washers made from?

These crush washers are made from aluminum. Aluminum is often used for crush washers because it's soft enough to crush and seal effectively without damaging the fitting or port.

About this part

Product Details

Vibrant Performance is known for making solid parts for engine builds and modifications. These aluminum crush washers are a simple but important piece of hardware when you're working with adapter fittings that have a straight thread, especially in ports that can't take a standard O-ring seal. They're a perfect match for Vibrant's own AN adapter fittings, ensuring a good seal where you need it most.

This pack comes with ten -8 AN size crush washers. They're made from aluminum, which is a good choice for this application because it deforms slightly to create a tight seal against the fitting and the port surface. If you're putting together a custom fuel system, oil cooler lines, or any other fluid transfer setup using AN fittings, having a few of these on hand is always a smart move to get a leak-free connection.
