Tube Bending Tolerances: Why ±1° and ±1/16″ Matter for OEM Fit
Tube bending tolerances define whether a fabricated part will function inside a larger OEM assembly. Two numbers determine qualification at TEC: ±1° angle tolerance and ±1/16" length tolerance. These are not aspirational targets - they are documented, repeatable minimums held across every part in every production run under ISO 9001:2015 quality controls. Key Takeaways ±1° angle tolerance and ±1/16" length tolerance are the documented minimums for OEM tube fabrication. These t
