#8 X #8 Inline Gauge Male/Female Adpt Fitting

The FRAGOLA #8 X #8 Inline Gauge Male/Female Adapter Fitting is a precision hydraulic or fuel system component designed to connect two 8 AN (JIC) ports while simultaneously providing a 1/8 inch NPT gauge port for pressure or fuel system monitoring. This straight-through adapter fitting enables seamless integration of analog gauges into high-pressure fluid lines without interrupting system flow or requiring external gauge isolation blocks.

Constructed from aluminum with blue anodized finish, the fitting offers corrosion resistance and durability in demanding environments. The 8 AN female port accepts standard -8 JIC hose assemblies or component outlets, while the 8 AN male port threads directly into female 8 AN receivers, creating a compact integrated solution. The 1/8 inch NPT gauge port is sized to accommodate standard automotive and racing gauge sending units, allowing real-time monitoring of fuel pressure, oil pressure, or hydraulic system conditions. Anodized aluminum provides weight savings critical in racing and high-performance applications while resisting oxidation in both dry and moisture-prone conditions.

This adapter is commonly specified in fuel system upgrades, hydraulic brake conversions, and performance engine builds where direct gauge access without system isolation is required. Street rod builders, circle track racers, and off-road enthusiasts rely on integrated gauge fittings to eliminate dedicated gauge blocks and reduce plumbing complexity. The straight configuration ensures minimal turbulence and pressure drop compared to angled designs, making it suitable for both fuel and hydraulic applications requiring accuracy in system diagnostics.

FRAGOLA has established itself as a trusted manufacturer of AN-series fittings and adapters used throughout the racing and custom vehicle community. This fitting's integration of male and female 8 AN ports with a gauge port simplifies system architecture and reduces the footprint of complex plumbing layouts common in modern performance engine compartments.
