Union AN 90 Degree Male -4

The Union AN 90 Degree Male -4 adapter from ALLSTAR PERFORMANCE is a vital hydraulic and fuel line fitting designed for high-performance engine builds and custom automotive applications. This compact adapter serves as a critical junction point in fuel delivery systems, power steering setups, and custom cooling circuits where precise line routing is essential.

Engineered to meet AN (Army-Navy) specifications, the -4 designation indicates a fitting compatible with standard -4 braided hose assemblies commonly used in fuel systems and hydraulic applications. The 90-degree male configuration allows hose lines to change direction without crimping or kinking, ensuring clean, reliable connections under pressure. Constructed from durable materials rated for high-temperature and high-pressure environments, this fitting is ideal for modified engines and performance vehicles.

Mechanics and fabricators rely on this adapter for fuel rail plumbing, remote filter mount installations, and custom manifold cooling circuits. Its compact footprint of 2.3 x 0.8 x 4.1 inches fits tight engine bays where space constraints demand precision fitting geometry. Installation requires AN-compatible braided hose for optimal performance.
