Description
ColorFittings AN ORB Plugs are precision CNC-machined to securely seal unused O-Ring Boss (ORB) ports in fuel, oil, coolant, transmission, hydraulic, and power steering systems. Designed with straight-thread ORB connections and an integrated O-ring sealing surface, these plugs provide a reliable, leak-free solution for closing unused ports in high-performance fluid systems.
Manufactured from aerospace-grade 6061-T6 billet aluminum and finished with ColorFittings’ proprietary polishing and anodizing process, these ORB plugs deliver exceptional strength, corrosion resistance, and long-term durability. The O-ring sealing design provides consistent performance in high-pressure and high-temperature environments without relying on thread sealant.
Compatible with E85, ethanol-based fuels, race fuel, pump gas, oil, coolant, transmission fluid, hydraulic fluid, and air systems, ColorFittings ORB Plugs are ideal for street performance, racing, off-road, marine, and custom fabrication applications.
