Endura Adapter Fitting #4 to 1/8 NPT 90 Degree

The Russell Endura Adapter Fitting #4 to 1/8 NPT 90 Degree is a precision-engineered hydraulic and pneumatic adapter designed to connect AN4 male fittings to 1/8-inch NPT male ports at a 90-degree angle. This nickel-anodized aluminum adapter delivers reliable fluid or gas line transitions in demanding applications where space constraints or plumbing geometry requires an elbow configuration rather than a straight fitting.

The 90-degree orientation allows technicians and system designers to route hose lines around obstacles, minimize bend radius on hoses, and optimize component layout within confined spaces—particularly valuable in automotive fuel systems, racing applications, industrial hydraulic circuits, and aerospace equipment. The AN4 to NPT conversion enables compatibility between systems using different thread standards, a common necessity when integrating OEM components with aftermarket or universal-fit hydraulic assemblies. Aluminum construction with nickel anodizing provides corrosion resistance in harsh environments while maintaining lightweight properties critical for performance-oriented vehicles and high-vibration installations.

Russell fittings are recognized across the automotive, marine, and industrial sectors for precise machining tolerances and reliable sealing performance. This adapter suits hot rod builders, restoration specialists, fleet maintenance operations, and engineers specifying fuel or coolant line adaptations. The compact 2.65 × 1.65 × 4.9-inch form factor and minimal 0.05-pound weight integrate seamlessly into systems where space and weight budgets are critical. Individual unit purchase allows custom configuration of multi-point hydraulic or pneumatic assemblies without committing to larger kit quantities.
