The #3 Aluminum Crushwashers from AEROQUIP are essential sealing components primarily used in fuel systems, brake lines, and cooling systems. These crushwashers are designed to prevent leaks in various automotive applications, ensuring reliable sealing performance under vibration and thermal cycling conditions.
Constructed from aluminum, these crushwashers compress under torque to conform to the seating surfaces of JIC and SAE fittings. They are inert to exposure from fuel, oil, coolant, and brake fluid, providing a soft-seal interface that prevents galling and corrosion. While they offer excellent sealing capabilities, it is important to note that they should be replaced after each disassembly.
Ideal for professional mechanics and fabricators, AEROQUIP crushwashers are commonly used in fuel system upgrades, turbo intercooler plumbing, and auxiliary transmission coolers. Their compatibility with standard -3 AN fittings and metric M10×1.0 port connections makes them a versatile choice for various automotive projects.
