Low Profile 10AN ORB Port Plug Clear

The Low Profile 10AN ORB Port Plug Clear from REDHORSE PERFORMANCE is an essential hydraulic line termination component for serious performance automotive builds and custom fuel system installations. Whether you're fabricating a custom fuel rail, setting up an aftermarket fuel pressure regulator system, or completing high-flow cooling modifications, this compact plug seals unused ORB (O-Ring Boss) ports cleanly and reliably. Designed for builders who demand precision engineering, this clear plug allows visual inspection of port integrity while maintaining a professional appearance on visible engine bay work.

Engineered with a low-profile design, this 10AN ORB port plug minimizes obstruction in tight engine compartments where space is at a premium—critical for turbocharged setups, supercharged platforms, and vehicles with restrictive bay geometry. The clear construction is manufactured from durable, fuel-resistant polycarbonate that withstands exposure to premium gasoline, ethanol blends, and methanol-enriched race fuel without degradation or cloudiness over time. The O-ring sealing surface provides a leak-free connection across standard ORB port threads, ensuring system integrity under pressure cycling and thermal expansion encountered in high-performance applications.

This plug suits custom fuel system builders, race engine fabricators, and modification enthusiasts performing port blocking on fuel manifolds, custom regulator manifolds, or auxiliary cooling lines. Installation is straightforward—thread the 10AN ORB plug into any standard ORB port and hand-tighten with a light wrench to seat the O-ring; no special tools are required. Compatible with any vehicle platform running ORB-threaded fuel or hydraulic components, from street turbo builds to dedicated road-race platforms. The compact 2.9 x 1.1 x 3.8 inch dimensions and lightweight 0.065 lb construction make it easy to store multiple plugs for different project phases.
