Straight Adapter Fitting #8 x 3/8 MPT

The Straight Adapter Fitting #8 x 3/8 MPT from FRAGOLA is a precision-engineered hydraulic line connector designed for high-performance fuel, oil, and coolant systems in modified vehicles. This adapter bridges AN8 (5/8"-18 JIC) female connections to 3/8" male pipe thread ports, making it essential for custom engine builds, fuel system upgrades, and aftermarket cooling installations.

Constructed from aluminum, this straight fitting is designed to handle demanding automotive applications while resisting corrosion and thermal cycling. The #8 JIC female port accepts standard AN8 hose fittings, while the 3/8" MPT end screws directly into factory or aftermarket manifold bosses, regulators, and block ports without requiring adapters or reducers. The straight design minimizes turbulence and maintains system pressure integrity.

Weighing only 0.04 lbs and measuring 4.05 inches in length, this compact connector fits seamlessly into confined areas while delivering reliable performance at full operating temperature. Mechanics and performance builders rely on this fitting for fuel systems, oil lines, and coolant applications, ensuring leak-free connections under pressure.
