Alm Crush Washers 3an 10pk

The Alm Crush Washers 3AN 10pk by FRAGOLA are essential sealing components for any serious fuel system or hydraulic line assembly. These crush washers create a reliable, leak-free connection at AN (Army-Navy) fittings, which are the industry standard for high-pressure automotive applications. They are particularly useful for applications involving fuel injection systems, custom fuel cells, and braided stainless steel fuel and coolant lines.

Crush washers work by deforming under the clamping load of an AN fitting's nut, creating a metal-to-metal seal that accommodates minor surface irregularities. This design is crucial for preventing leaks under pressure and vibration, especially in demanding environments like engine bays. The 3AN size is specifically designed for applications requiring precision hydraulic connections.

Mechanics and engine builders rely on these washers for fuel system fabrication, carburetor fuel line routing, and transmission cooler plumbing. The 10-pack provides ample inventory for complete fuel system builds and repairs, ensuring you have enough washers for multiple fittings and re-seating demands during tuning or troubleshooting. FRAGOLA's crush washers maintain dimensional consistency and material hardness for secure seals across all connections.
