6an to 3/8npt Adapter Fitting w/1/8npt port

The AEROQUIP 6AN to 3/8NPT adapter fitting with 1/8NPT port is a precision hydraulic and fuel system component designed for custom automotive applications where space and fluid routing flexibility are critical. This adapter bridges the gap between AN (Army-Navy) and NPT (National Pipe Thread) port standards, making it essential for builders transitioning between different system architectures on performance engines, fuel systems, and brake line configurations.

Constructed to meet high manufacturing standards, the 6AN to 3/8NPT adapter features a primary 6AN inlet/outlet, a 3/8NPT connection, and a 1/8NPT port for gauges, sensors, or vent lines. The 6AN specification (approximately 3/8-inch hose diameter) handles mid-range fuel and hydraulic flow rates without pressure loss, while the NPT threads accept standard pipe fittings and industrial components common in street rod and custom shop applications.

This adapter is ideal for hot rod builders, professional fabricators, and serious DIY mechanics looking to upgrade fuel delivery or hydraulic systems. AEROQUIP's manufacturing standards ensure consistent thread quality and leak-free performance under vibration and thermal cycling, which is critical for durability in engine bays.
