#8 Union

The EARLS #8 Union straight adapter fitting is a precision-engineered aluminum connector designed for high-pressure hydraulic and fuel line systems. This 8 AN male-to-male adapter joins two identical 8 AN hose ends or fittings in a straight orientation, maintaining full flow capacity without directional changes. The blue anodized finish provides corrosion resistance and a professional appearance across racing, automotive, and industrial applications.

EARLS fittings are engineered to SAE J518 and JIC standards, ensuring compatibility with AN-sized hose systems. The 8 AN designation indicates a nominal hose ID of 1/2 inch, rated for high-flow applications where pressure integrity is critical. Aluminum construction offers a weight advantage over steel alternatives while maintaining structural rigidity. The straight configuration eliminates the need for separate elbows or offset adapters, reducing connection points and potential leak paths in complex plumbing layouts.

This adapter suits engine builders, fuel system designers, and technicians managing multi-point hydraulic or fuel distribution. It is particularly valuable in applications where space constraints or system symmetry require direct male-to-male connections. The compact footprint (1.45 × 1.3 × 2.9 inches) makes it suitable for engine bays, frame rails, and tight underbody installations. Weighing only 0.05 lbs, the aluminum body minimizes parasitic weight in motorsports and aircraft applications where every ounce counts.

AN-sized fittings have been the industry standard for performance fuel and hydraulic systems for decades. The blue anodized finish signals EARLS' commitment to corrosion prevention in harsh environments—especially valuable for marine, off-road, and salt-air applications. When sourcing replacement adapters or expanding a fuel or brake line system, this straight #8 union ensures leak-free connections that meet or exceed OEM specifications.
