Weld-In Bung Fitting
Weld in threaded bungs are strong connections that are added to custom metal vehicle and engine components. JEGS offers a large supply of steel, aluminum, and stainless steel weld in bungs in stock from top manufacturers such as Vibrant, ICT Billet, Earl's, Russell Performance, JEGS, and others. Each bung fitting is made from heavy duty materials so you can get the leak-free connection you want at a price you can afford with the assurance you need.
If you really want a secure and stable fitting around an O2 sensor or a strong threaded port on a fuel tank, oil pan, transmission case or any custom fabrication project, a weld-in bung fitting is the way to go. Also known as pipe bungs, weld bungs are usually steel, stainless or aluminum and are a small-diameter cylinder with threads on one end, possibly a hex nut and an open hole on the other. A properly installed weld bung is how you can ensure a fitting that will be free of vacuum leaks or fluid leaks, and this is your resource for billet aluminum, steel or stainless weld bungs from brands like JEGS, Russell Performance, ICT Billet, Earl's and Vibrant Performance.
For someone with great welding skills and the right equipment and technique, weld-in bungs are versatile and offer a secure connection, making them an especially good option for custom fabrication jobs. They're not just for fittings and lines, either - a weld bung can be an anchor point for mounts, brackets, connectors and other components.
For aluminum bungs, remember that the material is softer so don't over-tighten when you connect a fitting or line to the bung. We also offer bungs with a barb-style fitting, making them a great choice for intake manifolds, vacuum line ports and hose connections of all kinds. Weld-in bung fittings from JEGS are a great option for an upgrade or restoration, or any time you need to manage a custom plumbing job that requires connections for hoses or lines with threaded connectors.

What Is a Weld In Bung?
A weld-in bung, sometimes referred to as a bung fitting or weld bung, is a small cylindrical metal component with threads on one end and an open hole on the other. These bungs are typically made of materials such as steel, stainless steel, or aluminum.
Weld-in bungs are used in various automotive and industrial applications, and their primary purpose is to provide a threaded connection point within a metal structure. The threaded end of the bung allows you to securely attach other components, such as fittings, sensors, or tubing.
These bungs are particularly popular in custom fabrication and modification projects where a threaded connection is needed in a specific location. They are commonly welded into exhaust systems, fuel tanks, oil pans, or any metal surface where a secure attachment point is required.
What Is a Weld In Bung Fitting Used For?
Weld-in bung fittings have a wide range of applications in automotive, industrial, and DIY projects. Some common uses include:
1. **Oxygen Sensors:** Weld-in bungs are often used to install oxygen sensors in exhaust systems for engine monitoring and emissions control.
2. **Fluid Systems:** They can be used in fuel tanks, oil pans, or transmission cases to provide threaded ports for hoses, lines, or temperature sensors.
3. **Custom Fabrication:** In custom fabrication projects, weld-in bungs serve as anchor points for various components, including brackets, mounts, and connectors.
Weld-in bung fittings offer versatility and a secure connection, making them essential in many applications where traditional threaded holes are not available.
How Much Does a Weld In Bung Fitting Cost?
The cost of a weld-in bung fitting can vary based on factors such as the material, size, and manufacturer. Here's a general price range to consider:
1. **Basic Steel or Aluminum Bungs:** Basic weld-in bungs made of steel or aluminum without any special features may start at around $5 to $10 per piece.
2. **Stainless Steel Bungs:** Stainless steel bungs, known for their corrosion resistance, are often priced higher and can range from $10 to $20 or more per piece.
3. **Size and Complexity:** Larger or more complex bungs, as well as those with additional features like pre-installed threads, may be priced higher.
Keep in mind that the quantity you need for your project will also impact the overall cost. Additionally, purchasing bungs in bulk may offer cost savings. It's essential to select bungs that meet your specific project requirements and material compatibility needs.
