90 Deg #4 > 1/8 Npt Stee

The 90 Deg #4 > 1/8 NPT Steel adapter fitting is a critical hydraulic and pneumatic line connector designed for professionals who demand reliable fluid transfer in demanding industrial and automotive applications. This 90-degree angle adapter bridges the gap between larger 4 AN (Army-Navy) male ports and smaller 1/8 inch NPT (National Pipe Tapered) male threads, making it indispensable for custom fuel systems, brake lines, coolant circuits, and air suspension setups where space constraints require compact routing.

Manufactured by EARLS—a trusted name in fluid system engineering—this fitting is constructed from hardened steel with a zinc-plated finish to resist corrosion and ensure durability in harsh environments. The 90-degree configuration allows hoses and tubes to navigate tight engine bays and chassis layouts without kinks or stress points that could compromise flow integrity or cause premature failure. The NPT male thread design creates a secure, leak-resistant seal when paired with NPT female ports, while the 4 AN male end accommodates standard braided stainless hose with appropriate crimped AN fittings, delivering the precision connection quality that professional mechanics and fabricators require.

This adapter serves race teams, restoration specialists, custom fabricators, and high-performance automotive builders who are routing fuel, oil, or coolant through unconventional paths. Its compact dimensions (1.15 x 0.95 x 3 inches) and lightweight construction (0.05 lbs) make installation straightforward in confined spaces, while the zinc-plated steel construction withstands vibration, temperature cycling, and chemical exposure common in modified engines and competition vehicles. Always ensure proper thread sealant application to NPT connections and verify line pressure compatibility before installation.
