Weld Bungs & Tube Adapters for Off-Road Fabrication

Heavy-duty weld-in tube adapters (weld bungs) for building suspension links, radius rods, steering links, and custom off-road fabrication. These threaded inserts allow chromoly heim joints or rod ends to be installed into suspension tubing for strong, adjustable link assemblies.

Available for the heim joint sizes we carry with multiple tubing diameters and wall thickness options, making it easy to match the correct adapter to your suspension build.

Choosing the Right Bung

Match the thread size to your heim joint and the OD to your tubing. Common pairings from our catalog:

1/2" thread — fits 1" OD and 1-1/4" OD tubing. Available in flanged and standard styles.

5/8" thread — fits 1-1/4" OD tubing at .095 wall.

3/4" thread — fits 1-1/2" OD and 1-3/4" OD tubing.

7/8" thread — fits 1-1/2" OD and 1-3/4" OD tubing at .120 wall.

If you're building a complete suspension link, check our rod end kits — they include the bungs, heim joints, jam nuts, and misalignment spacers as a matched set.
