Dom Tubing Specs

DOM tubing is quite a bit stronger in tension, and a lot stronger in resistance to bending in comparison to the ERW tube.  ID and OD and tolerances can be produced to a more exact specs.  It has the highest weld strength that is possible today.

DOM Tubing appears as if it is without a seam. Although it actually starts as a welded piece, the process makes its appearance nearly seamless. DOM tubing is suited for a wide range of structural and bushing applications. It is used in stressful applications requiring higher quality, uniformity, strength, and soundness.

Detroit Nipple Works offers DOM tubing in many specifications and sizes.
