Low Profile 12AN ORB Port Plug Clear

The Low Profile 12AN ORB Port Plug Clear from REDHORSE PERFORMANCE is a precision hydraulic fitting component designed for high-pressure fuel systems, coolant circuits, and transmission cooler lines in performance and custom vehicle builds. This compact adapter plug is essential for sealing open ORB (O-Ring Boss) ports when reconfiguring fuel rail layouts, upgrading cooling systems, or transitioning between different AN line configurations.

Constructed with a clear body for visual fluid monitoring and inspection, this 12AN ORB fitting is engineered to handle the high-pressure demands of modern fuel delivery and cooling systems without compromise. The low-profile design reduces installation footprint, which is critical in engine bays where space is limited around fuel injectors, manifolds, and intake runners. The ORB port configuration ensures a metal-to-metal face seal that eliminates reliance on tape or sealant, delivering consistent performance across temperature and pressure cycles.

Weighing just 0.08 lbs with compact dimensions of 2.9 x 1.1 x 3.8 inches, this fitting integrates seamlessly into tight packaging scenarios common in street rods, supercharged builds, and race-oriented fuel systems. Whether you're tuning a modified EFI engine or installing a custom radiator setup, this fitting is an essential component for maintaining system integrity and preventing fluid leakage at critical connection points.
