Endura Adapter Fitting #6 to 1/4 NPT 45 Degree

The Endura Adapter Fitting #6 to 1/4 NPT 45 Degree by RUSSELL is a precision hydraulic and fuel line adapter engineered for systems requiring angled transitions between metric and imperial thread standards. Designed for professionals in automotive, motorsports, marine, and industrial applications, this 45-degree fitting bridges AN6 (SAE -6) male connections to 1/4-inch NPT male ports with reliability and flow integrity. The angled configuration reduces pressure drops and installation stress compared to straight adapters, making it essential for custom fuel systems, turbo lines, and hydraulic layouts where space or alignment constraints demand directional transitions.

Constructed from lightweight aluminum and finished with nickel anodization, this adapter combines corrosion resistance with thermal stability across diverse fluid and temperature ranges. The nickel-plated surface protects against rust and oxidation while maintaining full compatibility with petroleum-based fuels, synthetic oils, and pressurized systems up to their rated capacity. The 45-degree bend geometry accommodates tight manifold configurations and engine bay layouts without requiring bulky elbows or multiple fittings, reducing assembly time and leak points. Each fitting is manufactured to RUSSELL's exacting standards, ensuring consistent thread geometry and seal surface finish for dependable performance in high-vibration and high-pressure environments.

This adapter is ideal for builders upgrading fuel delivery systems, installing aftermarket carburetors, or retrofitting hydraulic controls on performance engines and heavy equipment. The AN6-to-NPT conversion bridges metric fuel system standards common in modern engines with legacy or industrial NPT port configurations, eliminating the need for oversized transition blocks. Installation pairs seamlessly with standard SAE -6 hose and NPT gauge ports, sensor bungs, or tank fittings—simply apply thread sealant to the NPT end and torque to manufacturer specifications. Weighing just 0.06 lbs, this compact fitting minimizes system weight while delivering the angular clearance needed for routing around turbochargers, headers, and cylinder heads in space-constrained applications.
