Fragola -4AN Alum. Crush Washer -AN-901 10 Pack

When you're working on fuel or oil lines that use -4AN fittings, getting a good seal is critical to prevent leaks. These aluminum crush washers from Fragola are designed to help you achieve that secure seal. They're made from aluminum, which is softer than the fitting material, allowing it to deform and create a tight barrier against the fitting surface.

This 10-pack gives you plenty of washers for multiple jobs or for keeping spares on hand. They're a simple but essential component for ensuring your AN plumbing stays leak-free, whether you're building a custom fuel system or repairing an existing oil line. Just remember to replace them whenever you disconnect and reconnect an AN fitting to maintain that reliable seal.
