WOD 1.5" Tube Disconnect Flange Set
F021002
The Wide Open Design 1.50" Tube Disconnect Flange Set allows fabricators to build removable, bolt-together sections into tube chassis, roll cages, and custom structures. These flanges are ideal for engine cages, cooler racks, spare tire carriers, rear chassis sections, shock crossbars, and other assemblies that need to be removed for service or access.
Each flange is precision laser cut from 1/4" high-strength steel for clean weld preparation, consistent bolt alignment, and repeatable reassembly. Designed specifically for 1.50" OD tubing, this set provides a professional modular connection without requiring the surrounding tube work to be cut apart later.
Includes:
- (2) 1.50" Tube Disconnect Flanges
- Enough components for one complete bolt-together connection

Fitment
| Application | Common Use |
|---|---|
| Engine Cage | Creates removable tube sections for engine and accessory service |
| Cooler or Radiator Rack | Provides a removable support structure for easier maintenance |

| Rear Chassis Section | Improves access to drivetrain, suspension, or rear-mounted components |
| Shock or Crossbar Mount | Creates a serviceable upper bar or support structure |
Fitment Notes:
- Designed specifically for 1.50" OD steel tubing.
- Universal fitment for custom chassis, roll cages, race vehicles, and off-road fabrication projects.
- Both flanges must be aligned and welded square to prevent bolt binding during installation and removal.
- Mounting bolts, nuts, and washers are not listed as included.
- Tube ends should be properly fitted and centered before welding.
- Verify the remaining chassis structure is adequately supported when the removable section is taken out.
- Final connection strength depends on tube wall thickness, weld quality, bolt grade, and overall chassis design.
- Use in a primary roll cage or occupant-protection structure should be reviewed by a qualified fabricator and checked against applicable sanctioning-body rules.
FAQ
What are tube disconnect flanges used for?
Tube disconnect flanges create removable sections in welded tube structures. They are commonly used where access to engines, transmissions, cooling systems, suspension components, or rear-mounted equipment would otherwise require cutting the chassis apart.
Will these flanges fit 1.75" tubing?
No. This set is designed specifically for 1.50" OD tubing. Use the 1.75" Tube Disconnect Flange Set for 1.75" tubing.
Are the mounting bolts included?
The supplied product information lists two flanges as included but does not list mounting hardware. Select properly graded 3/8" bolts, nuts, and washers based on the load and intended use.
Can these flanges be used in a roll cage?
They can be used in custom tube structures, but removable connections in primary occupant-protection areas may be restricted by racing or safety regulations. Confirm the design with a qualified chassis fabricator and the applicable rulebook before installation.
How should the flanges be aligned before welding?
Bolt the two flanges together, fixture the tubing in its final position, and tack both sides before completing the welds. After cooling, verify that the hardware removes and reinstalls freely and that the tube section remains properly aligned.
