Octopus Orb Brass 90° Elbow - ORB 5 to 3/8" Compression

The Octopus Orb Brass 90° Elbow - ORB 5 to 3/8" Compression is a critical hydraulic and pneumatic fitting designed for fuel systems, coolant lines, and brake applications where reliable directional flow control is essential. As a mechanic or automotive technician, you'll recognize this as a necessity for custom fuel system builds, engine bay modifications, and performance plumbing work where space constraints demand a compact 90-degree connection. The elbow configuration allows you to redirect fluid or gas flow while maintaining system integrity and preventing leaks at high pressures common in modern fuel injection and turbo cooling circuits.

Constructed from premium brass, the Octopus Orb fitting delivers superior corrosion resistance and durability in both hot and cold engine environments. The ORB (O-Ring Boss) port rated at size 5 accepts industry-standard O-ring seals, ensuring a metal-to-metal compression fit that outperforms traditional NPT threads in vibration-prone applications. The 3/8-inch compression outlet provides a secure connection to smaller diameter tubing, making this elbow ideal for secondary cooling lines, catch can plumbing, or auxiliary fuel system branches where stepped-down line sizing is required. Brass construction also allows for safe use with both synthetic and conventional fluids without degradation.

This fitting benefits engine builders, fuel system specialists, and DIY enthusiasts tackling turbo upgrades, fuel system relocations, or custom cooling loops where precision plumbing matters. Its compact 1-inch profile fits tight engine compartments without requiring extensive rerouting of existing lines. The 90-degree angle eliminates the need for multiple adapters or bends, reducing potential leak points and simplifying installation. Whether you're routing coolant to an auxiliary radiator, branching a fuel return line, or setting up a catch can system on a modified engine, this Octopus fitting delivers reliable performance and long-term dependability in demanding automotive applications.
