Low Profile 12AN ORB Port Plug Clear

The Low Profile 12AN ORB Port Plug Clear from REDHORSE PERFORMANCE is a precision hydraulic fitting component engineered 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. Whether you're tuning a modified EFI engine, installing a custom radiator setup, or executing a full fuel system overhaul, this low-profile design eliminates unnecessary port blockage while maintaining system integrity and preventing fluid leakage at critical connection points.

Constructed with a clear body for visual fluid monitoring and inspection, this 12AN ORB fitting employs a robust design that handles the high-pressure demands of modern fuel delivery and cooling systems without compromise. The low-profile geometry reduces installation footprint—critical in engine bays where space is at a premium 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 system architectures.

Professional mechanics and enthusiasts upgrading to custom fuel rails, aftermarket fuel pumps, or turbo cooling systems rely on REDHORSE PERFORMANCE fittings for their durability and precision engineering. This plug excels in applications where port consolidation or system reconfiguration demands a reliable, low-profile solution without sacrificing pressure rating or seal integrity. Compatible with any 12AN ORB port on fuel systems, transmission coolers, or engine coolant passages, installation requires only hand-tightening with a wrench—no special tools needed. For anyone executing a comprehensive fuel system modification or cooling circuit upgrade, the Low Profile 12AN ORB Port Plug Clear delivers the precision fit and leak-free performance that separates a quality build from a problematic one.
