#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. Whether you're upgrading a street machine's fuel delivery or fabricating a custom racing platform, this ORB adapter ensures leak-free connections that withstand vibration, temperature cycling, and sustained pressure loads that would compromise inferior fittings.

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. The lightweight 0.02 lbs design adds negligible weight while the compact 3.2-inch body fits tight spaces where larger adapters would create packaging conflicts around headers, intake manifolds, or tight turbo installations.

Mechanics and fabricators building forced-induction systems, fuel system upgrades, or precision brake line routing benefit from FRAGOLA's reputation for engineering durability under extreme PSI. This fitting pairs seamlessly with braided stainless steel hose assemblies, regulator manifolds, and custom fuel system components common in street rods, muscle cars, and track-focused builds. Installation requires hand-tightening with a wrench to snug—over-torquing compromises the O-ring seal, so controlled assembly ensures years of leak-free operation. Stock this versatile adapter in your shop or build kit for emergency system repairs and custom fabrication projects where a single failed fitting can sideline an entire vehicle.
