Fragola 3/8 FPT Steel Weld Bung

This is a Fragola 3/8 FPT steel weld bung, part number 596703. It's a straightforward piece of steel designed to be welded onto an exhaust system or other fabricated metal component. The 3/8 FPT (Female Pipe Thread) means it has internal threads that accept a 3/8 inch pipe thread fitting, commonly used for sensors, gauges, or small plumbing lines.

Made from steel, this bung is intended to be welded into place, so you'll need welding experience and the proper equipment to install it. It's a simple but essential part for custom fabrication projects where you need to add a threaded port to a surface. Think of it as a clean way to add a connection point for things like oxygen sensors, vacuum lines, or pressure gauges to your custom exhaust or intake piping.
