This product is particularly beneficial for mechanics and automotive enthusiasts who are building or upgrading hydraulic and pneumatic circuits. Its reliability is essential for ensuring precision connections in various automotive applications.
Constructed from lightweight aluminum, the #4 AN fitting is engineered to reduce unsprung weight while maintaining structural integrity under pressure. The AN (Army-Navy) specification guarantees consistent thread geometry and sealing surface angles, allowing this Aeroquip nut to mate reliably with standard #4 AN tubing and hose assemblies. This ensures a secure fit that is crucial for preventing leaks.
Ideal for applications such as custom fuel systems and intercooler plumbing, this fitting is a must-have for anyone working on turbocharged or heavily modified engines. Its compact size of 2.2 x 1.1 x 3.7 inches and minimal weight of 0.07 lbs make it suitable for tight engine bays where space and weight savings are paramount. Always pair the #4 AN tube nut with matching #4 AN tubing and hose for optimal performance.
