#3 x 3/8-24 ORB Fitting Black

The #3 x 3/8-24 ORB Fitting Black by FRAGOLA is a precision hydraulic adapter essential for custom fuel injection systems, nitrous oxide delivery lines, and high-pressure brake applications in performance vehicles. This compact fitting serves as a critical junction point in fuel system builds, turbo installations, and engine bay modifications where reliable fluid transfer under extreme conditions is non-negotiable.

The #3 ORB port configuration features a standard O-ring boss design that creates a metal-to-metal seal, eliminating the thread-sealing tape or compound failures that plague Teflon-sealed connections in high-vibration environments. The 3/8-24 thread specification matches common fuel rails, regulator ports, and filter heads found in both carbureted and EFI conversions, allowing seamless integration into existing plumbing. FRAGOLA's black finish resists corrosion from fuel exposure and coolant splash while maintaining a clean, professional appearance in engine bays.

Mechanics and fabricators will appreciate the lightweight design that adds negligible weight, while the compact body fits tight spaces where larger adapters would create packaging conflicts around headers, intake manifolds, or tight turbo installations. This fitting is ideal for those upgrading street machines or fabricating custom racing platforms, ensuring leak-free connections that withstand vibration, temperature cycling, and sustained pressure loads.
