Gauge Adapter 1/8in NPT Female to -4an Male

The Gauge Adapter 1/8in NPT Female to -4AN Male from QuickCar Racing Products is a precision fluid system component designed for professionals and enthusiasts who demand reliable, leak-free connections in high-pressure racing and tactical applications. This adapter bridges two industry-standard thread types, enabling seamless integration between NPT (National Pipe Tapered) gauge ports and AN (Army-Navy) flange fittings. Whether you're building a custom fuel system, hydraulic circuit, or specialized fluid monitoring setup, this adapter eliminates guesswork and ensures compatibility across different component families.

Engineered with precision-machined construction, the 1/8in NPT Female to -4AN Male adapter features NPT female threads on one end, which seat using a tapered thread cone for a mechanically locked, vibration-resistant connection. The -4AN male end accepts standard -4 size AN flange fittings, commonly found in fuel injection systems, pressure relief circuits, and test instrumentation. The compact 0.07 lb profile and minimal footprint (3.45 x 0.65 x 4.5 inches) make it suitable for space-constrained engine bays and tactical vehicle builds where routing flexibility is critical. QuickCar's quality manufacturing standards ensure zero drip-down, critical for maintaining system cleanliness and preventing fluid contamination in sensitive gauges or controls.

Military vehicle technicians, racing engineers, and custom fabricators benefit most from this adapter when retrofitting modern AN-spec fuel or hydraulic lines into legacy NPT gauge bosses, or when integrating aftermarket telemetry into factory engine blocks. Installation is straightforward: apply appropriate thread sealant (PTFE tape or anaerobic compound) to the NPT male threads, hand-tighten into the female gauge port, and secure the -4AN fitting using a wrench. Compatible with all standard -4AN hose assemblies and gauge ports featuring 1/8in NPT internal threads, this adapter is a must-have for builders demanding professional-grade fluid system reliability.
