Low Profile ORB Port Plu g -12 AN

The Low Profile ORB Port Plug -12 AN from VIBRANT PERFORMANCE is a compact, lightweight adapter engineered for high-performance fuel, coolant, and fluid line applications in custom automotive builds. Designed for mechanics and enthusiasts who demand precision plumbing in tight engine bays, this fitting serves as a dead-end port closure for ORB (O-Ring Boss) manifolds and hard-line systems. Whether you're running a custom fuel rail, turbo cooling circuit, or high-flow coolant bypass, this plug eliminates the need for bulky fittings or unused port caps that compromise airflow and aesthetics.

This low-profile design fits seamlessly into confined spaces where standard plugs won't work, allowing you to maximize underhood real estate without sacrificing function. The -12 AN designation indicates a 3/4-inch ORB boss connection—a metric standard in performance fuel systems and engine management plumbing. Manufactured to VIBRANT PERFORMANCE's exacting standards, the fitting features precision-machined construction and reliable O-ring sealing to prevent leaks under pressure. At just 0.05 lbs and compact dimensions (3.54 x 0.5 x 6.3 inches), it adds negligible weight while delivering the durability required for high-pressure applications, making it ideal for fuel injection, forced induction cooling loops, and modular engine bay configurations.

This plug is essential for custom-built systems where factory port configurations don't match your modifications. Professional tuners, turbo installers, and DIY enthusiasts building bespoke fuel delivery or cooling systems will appreciate the space savings and clean integration. Install it anywhere an ORB port requires closure without running an active line—perfect for sealed manifold blocks, unused fuel rail ports, or test points on custom hard-line assemblies. Pair it with complementary VIBRANT PERFORMANCE ORB adapters and fittings to create a complete, leak-free fluid routing system tailored to your engine's performance demands.
