#16 Tube Nut

The #16 Tube Nut by FRAGOLA is a precision-engineered fitting component designed for high-performance fluid transfer systems in racing, automotive, and hydraulic applications. This aluminum tube nut serves as a critical connector in brake lines, fuel systems, and coolant circuits where reliable, leak-free connections are non-negotiable. Built to AN (Army-Navy) standards, the #16 Tube Nut accommodates 1-inch tubing and is essential for technicians and builders who demand OEM-quality performance without compromise.

Manufactured from lightweight aluminum and finished in blue anodized coating, this fitting provides excellent corrosion resistance while maintaining structural integrity under pressure and vibration. The blue anodized finish not only protects against oxidation but also aids in system identification and aesthetic appeal in visible engine bays. The AN16 specification ensures compatibility with standard -16 tubing sizes and meets strict aviation and automotive certification requirements, delivering repeatable torque values and consistent thread engagement that prevents stripped connections and system failures.

This tube nut is ideal for restoration projects, custom fabrication, and OEM replacements in vehicles requiring precision fluid handling. Whether assembling a complete brake system, upgrading fuel delivery on a performance engine, or rebuilding hydraulic circuits, the #16 Tube Nut integrates seamlessly with FRAGOLA's full line of AN fittings and adapters. Installation is straightforward—simply match the 1-inch tubing size and apply appropriate torque per AN specifications; the aluminum construction keeps overall system weight minimal while the blue anodized durability ensures years of leak-free service in demanding environments.
