What is the purpose of a crush washer?

A crush washer is used to create a seal between a fitting and a port. It deforms slightly when tightened, filling any small imperfections and preventing leaks, especially on straight thread fittings where an O-ring isn't suitable.

What sizes of AN fittings are included in this set?

This set includes 10 crush washers each for -3AN, -4AN, -6AN, -8AN, -10AN, -12AN, and -16AN fittings, totaling 70 washers.

What material are these crush washers made from?

These crush washers are made from a 6061 aluminum alloy, which is a common and well-suited material for this type of sealing component.

About this part

Product Details

When you're working on sealing adapter fittings that have a straight thread and don't have a place for an O-ring, you need a crush washer to get a good seal. This box set from Vibrant Performance gives you a good selection of aluminum crush washers for those jobs. They're made from 6061 aluminum alloy, which is a solid choice for this application.

This set includes 10 washers each of sizes -3AN through -16AN, giving you 70 total washers. That's a lot of common sizes to have on hand, so you're ready for a variety of setups. They're designed to work with Vibrant's own AN adapter fittings, but they'll work with other brands too, as long as the threads are straight and you need a crush seal.
