7-8 in - 14 tpi for 1.0in ID - 1.5in OD - Tube Adapter
The Artec Industries 7/8"-14 Tube Adapter is a weld-in threaded insert for building your own adjustable suspension links, steering bars, and control arms. Its 1.0" inside diameter and 1.5" outside diameter are sized to drop into common 1.5" OD, 0.250" wall DOM tubing, giving you a tight, high-strength joint that accepts 7/8"-14 rod ends or threaded bungs. It is offered in both right-hand (standard) and left-hand (reverse) thread so a single tube can be adjusted for length without disconnecting either end.
Key Features
- 7/8"-14 TPI threads with full-length threading for maximum, positive thread engagement
- 1.0" inside diameter matches the tube bore for a tight, strength-adding press fit
- 1.5" outside diameter matches thick-wall tubing for a clean, sleek finished link
- Beveled edge for easy welding with no pre-grinding required
- Flat land on the OD so the weld edge does not sit on an angled surface
- Wrench flats for simple length adjustment and a smooth appearance
- Available in right-hand standard (TA1401R) and left-hand reverse (TA1401L) thread
Fitment & Compatibility
This is a universal fabrication component, not a vehicle-specific part. It is designed to weld into 1.5" OD tubing with a 1.0" inside diameter (nominally 0.250" wall DOM) and to thread onto 7/8"-14 rod ends or heim joints. Pair a right-hand and a left-hand adapter on the same tube to create a fully adjustable link. Confirm your tube ID and thread pitch before ordering.

Frequently Asked Questions
What size tube does this adapter fit?
It is made for 1.5" outside-diameter tubing with a 1.0" inside diameter, which corresponds to nominal 0.250" wall DOM. The 1.0" ID slides into the tube bore and the 1.5" OD matches the outside of the tube for a flush weld.
Do I need both left-hand and right-hand adapters?
For an adjustable link you do. Weld a right-hand (TA1401R) adapter on one end and a left-hand (TA1401L) adapter on the other so the assembly acts like a turnbuckle and can be lengthened or shortened without unbolting.
Does it need to be welded?
Yes. This is a weld-in bung. The beveled edge and flat OD land are shaped to make welding easy and clean with no grinding beforehand.
What rod ends does it accept?
Any 7/8"-14 TPI rod end or heim joint, such as Artec's JMX PRO 7/8" rod ends. Add a matching 7/8"-14 jam nut to lock the joint at your final length. Pair with DOM link tubing to complete the build.
