1.25" Standard Tube Adapter Right Hand 1.5(ID) 12(TPI)

1.25" Standard Tube Adapter – Right Hand, 1.5" ID, 12 TPI

Weld-in Bung for 1.5” ID Tubing | Fits 1.25” RH Heim Joints

This right-hand thread tube adapter is built for 1.25” Heim joints and fits 1.5” ID DOM tubing — perfect for .120" or .250" wall. Designed for the lower links and high-impact zones on your suspension, this is the bung that’s going to see the dirt and take the hits.

We machine these to allow most of the Heim shank to seat deeper inside the tube, giving it more support and increasing strength at the weld point. It’s not chromoly, but it’s built smart and built to last.

Welding Tips: Start your weld on the tube, not the adapter. Never weld with the rod end threaded in. Let the part cool fully before installing Heim joints to avoid thread warping or seizing.
