#10 ORB to 3/8 Male Q/C EFI Fitting Straight

The #10 ORB to 3/8 Male Q/C EFI Fitting Straight by FRAGOLA is a precision hydraulic and fuel system adapter designed for high-performance automotive and motorsports applications. This straight configuration connects a 10 AN male O-ring boss port to a 3/8-inch male quick-disconnect coupling, enabling rapid system assembly and disassembly without fluid spillage. Engineers and technicians choose this fitting when building custom fuel injection systems, transmission cooler lines, or high-pressure hydraulic circuits where reliability and leak-free connections are non-negotiable.

Manufactured from aircraft-grade aluminum and finished in black anodized coating, the #10 ORB to 3/8 Male Q/C EFI Fitting Straight delivers corrosion resistance and durability in demanding under-hood and external environments. The O-ring boss design creates a metal-to-metal seal that accommodates the elastomer O-ring, eliminating the need for thread sealant and reducing contamination risk in fuel or coolant circuits. The integrated quick-disconnect coupling allows technicians to connect and disconnect lines repeatedly without tools, a critical advantage during installation, maintenance, or component swaps on race vehicles and custom builds.

This fitting is ideal for builders working with EFI fuel systems, radiator bypass circuits, and modular engine bays where space constraints and frequent service access demand flexible connections. Its compact footprint (2.9 × 1.6 × 2.95 inches) and lightweight design (0.07 lbs) make it suitable for weight-sensitive applications. Compatibility spans most carbureted-to-fuel-injection conversions, custom cooling loops, and aftermarket fuel pressure regulators that utilize 10 AN male O-ring boss inputs and 3/8-inch quick-disconnect female couplings.
