#6 Male x 3/8 MPT Gauge Adapter Inline

The FRAGOLA #6 Male x 3/8 MPT Gauge Adapter Inline is a precision-engineered fitting designed to integrate pressure gauges into high-performance fluid systems. This straight adapter connects a #6 AN male port directly to a 3/8-inch NPT male line while providing a dedicated 1/8-inch NPT gauge port, enabling accurate real-time pressure monitoring without disrupting primary flow paths. Built from aluminum and finished in black anodize, this adapter delivers the corrosion resistance and lightweight construction demanded in racing, marine, hydraulic, and fuel system applications.

The inline gauge port configuration eliminates the need for external tee fittings, streamlining system design and reducing clutter in engine bays or machinery compartments. The #6 AN to 3/8 NPT conversion accommodates the most common coupling standards across aftermarket and OEM systems, while the 1/8-inch NPT gauge outlet accepts standard pressure transducers and analog gauges. Black anodized aluminum resists oxidation in aggressive environments—particularly valuable in salt-air coastal applications, humid shop conditions, or fuel-system service where corrosion degrades bare aluminum quickly. The compact straight-through design maintains consistent pressure readings without restriction or turbulence at the gauge tap.

This adapter serves professional engine builders, fuel system technicians, marine mechanics, and off-road enthusiasts who require visible pressure diagnostics during tuning, troubleshooting, or competition. Whether monitoring fuel pressure on a turbocharged engine, tracking hydraulic pressure on a winch or hoist, or verifying coolant circulation on a high-performance cooling loop, the inline gauge port delivers critical data at the point of installation. The adapter's lightweight aluminum construction makes it ideal for weight-sensitive applications including race vehicles and marine propulsion systems where every pound matters.
