20an Union Adapter Fitting

The 20 AN Union Adapter Fitting from FRAGOLA is a straight-through connector designed for high-pressure hydraulic and fuel line applications where two 20 AN male ports must be joined. This adapter fitting serves as an essential component in custom fuel systems, hydraulic assemblies, and motorsport applications where secure, leak-free connections are non-negotiable. Built to withstand demanding conditions, the 20 AN Union Adapter Fitting is engineered for professionals and enthusiasts who require reliable, military-grade fluid management solutions.

Constructed from aluminum and finished in black anodized coating, this fitting provides both corrosion resistance and durability in high-temperature environments. The straight-through design eliminates flow restriction and turbulence, critical for maintaining system efficiency in fuel injection, cooling, and hydraulic circuits. The black anodized finish not only protects the aluminum base from oxidation and chemical degradation, but also delivers the tactical aesthetics preferred in engine bay builds. The 20 AN male-to-male configuration allows seamless integration into existing AN plumbing systems without the need for additional adapters or reducers.

Professional mechanics, race teams, and custom vehicle builders rely on FRAGOLA fittings for their precision engineering and consistent performance under pressure. The 20 AN Union Adapter Fitting is ideal for fuel cell installations, turbo feed/return lines, transmission coolers, and any application requiring a straightforward coupling of two AN male connections. At 0.25 lbs and compact dimensions of 2.9 x 2.45 x 3.65 inches, this fitting integrates cleanly into tight engine bays without adding unnecessary weight. Proper AN thread sealant and correct torque specifications ensure maximum service life and system integrity.
