What is the purpose of an aluminum crush washer?

An aluminum crush washer is designed to deform slightly when tightened, creating a seal between a fitting and a port. It's particularly useful for straight thread fittings where an O-ring can't be used to prevent leaks.

Can I use these crush washers with fittings from other brands?

While these M8 aluminum crush washers are specifically designed to work with Vibrant Performance AN adapter fittings, they can often be used with other brands' fittings that have a compatible M8 straight thread and require a crush washer for sealing.

How many crush washers are included in this pack?

This pack includes ten M8 aluminum crush washers. Having multiple on hand is useful for projects requiring more than one fitting or as spares.

About this part

Product Details

These M8 aluminum crush washers from Vibrant Performance are a smart choice when you need to seal adapter fittings that use a straight thread and don't have a place for an O-ring. They're made from aluminum, which is a softer metal than the fitting or the port, allowing it to deform and create a tight seal. This pack comes with ten washers, so you'll have spares on hand for multiple projects or if one gets damaged during installation.

They are specifically designed to work with Vibrant Performance AN adapter fittings, ensuring a good match and a reliable seal. When you're working with straight thread ports that need a dependable seal without an O-ring, these crush washers are a straightforward solution.
