Adapter Fitting Bulkhead Straight 16an

The Adapter Fitting Bulkhead Straight 16AN from EARLS is a precision hydraulic and fluid-transfer coupling engineered for high-performance automotive, aerospace, and industrial applications. This bulkhead straight adapter connects two 16 AN male ports and is designed to mount flush through a panel or bulkhead, eliminating external protrusions and simplifying compartmentalization of fluid systems. It is ideal for builders and technicians who require compact, reliable fittings in space-constrained environments where leakage and vibration resistance are non-negotiable.

Manufactured from lightweight aluminum and finished in black anodize, this bulkhead fitting offers superior corrosion resistance and durability in demanding conditions. The anodized coating protects against oxidation and wear, extending service life in salt-spray, moisture-rich, and chemically aggressive environments. The straight 16 AN male-to-male configuration ensures proper flow dynamics and minimal turbulence, critical for maintaining system pressure and protecting against cavitation in fuel, coolant, and hydraulic circuits. Its compact design—measuring 2.55 × 1.95 × 3.85 inches and weighing just 0.23 lbs—makes installation straightforward without adding significant mass.

This fitting is essential for custom fuel systems, race car builds, custom water-cooling loops, and any modular fluid application requiring a bulkhead pass-through. Installation requires drilling or routing a properly sized bulkhead hole and securing the adapter from both sides with appropriate wrenches. Compatible with all 16 AN hose and hard-line assemblies, this EARLS adapter integrates seamlessly into existing systems and meets or exceeds performance standards for high-pressure applications up to typical 16 AN system ratings. Professionals and enthusiasts alike rely on EARLS quality for leak-free, vibration-damped connections.
