Female Inline Fitting #6 Male x -6 1/8 FPT

The FRAGOLA Female Inline Fitting #6 Male x -6 1/8 FPT (Part No. 495005-BL) is a precision gauge adapter designed for high-pressure hydraulic and fuel line systems. This straight-configuration fitting connects a #6 AN female port to a #6 AN male connection while providing a dedicated 1/8-inch NPT port for pressure gauge installation, making it an essential component for systems requiring real-time pressure monitoring during operation or diagnostics.

Constructed from lightweight aluminum and finished in black anodize coating, this fitting delivers corrosion resistance and durability in demanding environments. The #6 AN specification (3/8-inch SAE J518 ported connection) is standard across high-performance fuel systems, supercharger boost lines, and transmission cooler circuits. The 1/8-inch NPT gauge port accepts standard automotive and industrial pressure transducers, allowing direct integration into telemetry systems or mechanical gauge clusters without requiring additional adapter hardware. The straight-body design minimizes flow restrictions and pressure drop while maintaining structural integrity under peak system loads.

This fitting serves motorsports enthusiasts, diesel truck builders, and performance tuners who need reliable pressure-monitoring capabilities. Common applications include EFI fuel rail systems, turbo boost lines, and differential cooler circuits where inline gauge ports are critical for monitoring system health and tuning accuracy. The black anodized finish provides visual consistency with modern performance fuel system assemblies while protecting against oxidation in salt-air or high-humidity storage environments.

FRAGOLA fittings are engineered to ISO 6149 and SAE J518 standards, ensuring compatibility across OEM and aftermarket fuel system platforms. This particular configuration supports systems rated for pressures typically encountered in fuel injection and boost applications, with thread sealing achieved through standard PTFE tape or thread-sealant compounds on the NPT gauge port.

Each unit ships as a single fitting with no additional adapters or plugs included, allowing custom gauge port configuration to match specific monitoring requirements.
