Tubing 1.00 x.120 Round D.O.M. ALL22127-4

OVERVIEW

When it comes to custom fabrication for your off-road rig or classic air-cooled project, the quality of your raw materials defines the safety and longevity of the entire build. This Allstar Performance 1.00-inch OD x .120-inch wall thickness D.O.M. (Drawn Over Mandrel) tubing is the gold standard for builders who refuse to compromise on structural integrity. Unlike standard ERW (Electric Resistance Welded) tubing which has a visible and potentially weak welded seam, D.O.M. tubing undergoes an intensive additional cold-drawing process over a mandrel. This procedure not only removes the internal seam but also significantly improves the steel''s concentricity, surface finish, and overall tensile strength. For the VW enthusiast building a rugged Baja Bug or a high-performance sand rail, this tubing provides the predictable bending and superior welding characteristics required for high-stress components that must endure extreme vibration and impact.

At Appletree Auto, we know that the difference between a successful trail run and a mechanical failure often comes down to the wall thickness and material grade of your fabrication components. This specific .120-wall tubing is exceptionally versatile, offering a heavy-duty profile that is ideal for steering links, suspension stays, and chassis bracing. Its 1-inch diameter makes it a popular choice for secondary roll cage bars, grab handles, and custom light bars where weight savings must be balanced with structural rigidity. Whether you are reinforcing a classic Type 1 floor pan or building a completely custom tube-frame buggy from the ground up, this Allstar Performance tubing ensures that your welds penetrate deeply and your bends remain uniform, giving your project a professional, race-ready finish that stands up to the harshest desert or street conditions. Don''t settle for inferior materials when your safety is on the line; choose the tubing trusted by professional fabricators across the globe.

PRO TIPS

1. Proper Surface Preparation for Welding

D.O.M. tubing often arrives with a light coating of oil or "mill scale" to prevent rust during shipping. Before you strike an arc, it is absolutely critical to clean the weld zone thoroughly. Use a flap disc or a wire wheel to strip the steel down to a bright, shiny finish at least one inch back from the joint. If you are using TIG welding, follow up with an acetone wipe to remove any residual oils. Proper cleaning ensures maximum weld penetration and prevents porosity, which is vital for structural components like roll cages or steering links where a weld failure could be catastrophic.

2. Precision Bending Techniques

When bending 1.00-inch x .120-wall tubing, always use a high-quality mandrel bender or a heavy-duty manual tube bender with the correct 1-inch radius die. Because .120 is a relatively thick wall for a 1-inch tube, it resists kinking better than thinner materials, but you still need to ensure the tube is properly supported in the die. Avoid using "pipe" benders from hardware stores, as these are designed for Schedule 40 pipe and will likely crush or deform the round tubing. Always account for "spring-back"the tendency of the metal to relax slightly after the pressure is releasedby over-bending by approximately 2 to 5 degrees depending on your specific tool.

3. Managing Heat and Warpage

Fabricating suspension links or chassis braces requires careful heat management. When welding brackets or tube inserts into this .120-wall tubing, try to use a "stitch weld" technique or alternate sides to prevent the tube from bowing or warping. If you are welding a threaded bung into the end of the tube for a rod end, consider threading a sacrificial bolt into the bung during the welding process to prevent the threads from distorting due to the high heat. Once the weld is complete, allow the piece to air-cool naturally; never quench it in water,
