Weld-In Bung Fitting

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.
