14mm Aluminum Crush Washers (10pk)

The FRAGOLA 14mm Aluminum Crush Washers (10-pack) are essential sealing components for any high-performance fuel system, hydraulic line, or fluid transfer application where precision leak-free connections are critical. These washers are ideal for mechanics and automotive enthusiasts who require reliable seals in various applications, including custom fuel rails and turbo feed lines.

Manufactured from lightweight aluminum alloy, the 14mm crush washers conform under bolt torque to fill micro-imperfections between connection faces, ensuring a dependable metal-to-metal seal. The crush design allows each washer to deform permanently when tightened, preventing leaks even under pressure spikes or thermal cycling typical in performance fuel systems. This material choice offers a softer sealing surface than steel while maintaining structural integrity and resisting corrosion from fuel and coolant exposure.

Engine builders, fuel system technicians, and serious DIY modifiers rely on FRAGOLA crush washers for applications such as fuel injector lines, AN-fitting assemblies, turbocharger feed and return lines, and oil supply manifolds. With their proven performance and durability, these washers are a go-to choice for anyone looking to ensure leak-free connections in demanding environments.
