Vibrant 321 stainless steel straight tubing measures 2.5 in OD by 39.375 in length with an 18-gauge wall (0.049 in thickness) and is recommended where prolonged elevated temperatures are expected. 321 stainless offers improved resistance to high-temperature oxidation and stress versus 304, making this tubing suitable for forced induction and other high-heat exhaust or turbo plumbing applications.
