5/8"-18 Weld-In Tube Adapter – 1" OD x .120" Wall Tubing
1844-122
The 5/8"-18 Weld-In Tube Adapter for 1" OD x .120" Wall Tubing provides a strong, clean way to install 5/8"-18 rod ends into suspension links, chassis components, steering linkages, and other fabricated tube assemblies. CNC machined from weldable chromoly alloy steel, the adapter is sized specifically for 1" OD tubing with a .120" wall thickness.
Available in both right-hand and left-hand thread configurations, these adapters make it easy to build adjustable links using opposing thread directions. The left-hand thread version features a machined identification groove around the outside so it can be quickly identified during fabrication, adjustment, or service.
Includes:
- (1) 5/8"-18 Weld-In Tube Adapter
- Choice of Left-Hand or Right-Hand Thread
Note: Left-hand thread version includes a machined external identification groove.

FAQ
What size tubing does this weld-in adapter fit?
This adapter is designed specifically for 1" outside diameter tubing with a .120" wall thickness.
What rod end fits this tube adapter?
It accepts rod ends or other components using a 5/8"-18 male thread.
Why would I use both left-hand and right-hand tube adapters?
Using a left-hand adapter on one end of a link and a right-hand adapter on the other allows the finished link to be lengthened or shortened by rotating the tube without removing the rod ends from their mounts.
How can I identify the left-hand thread adapter?
The left-hand version has a machined groove around the outside of the adapter, making it easy to identify once installed.
Does this adapter weld directly into the tubing?
Yes. It is a weld-in adapter machined from weldable chromoly alloy steel. Proper tube preparation, fitment, and welding procedures should be used for the application.
