Radium Engineering Universal 4AN Orb Plug

When you're fabricating custom fuel or oil lines, sometimes you need to close off a port on a fitting or manifold. This universal 4AN orb plug from Radium Engineering is designed for just that purpose. It's a clean way to seal off an unused 4AN port on your setup.

This plug is CNC machined from aluminum for a good balance of strength and light weight. It features a low-profile socket head design, which means it sits flush or nearly flush once installed, keeping your engine bay looking tidy. The black anodized finish not only looks sharp but also adds a layer of corrosion resistance. It's a well-built piece that makes closing off those ports a simple task.
