Electropolished Tubing from AMETEK O'Brien

Electropolished Tubing
O’Brien Analytical TrueTube® EP is electropolished select grade 316L SS tubing. Electropolishing not only improves surface roughness but also enhances the corrosion resistance by leaving a chromium enriched surface layer. Our proprietary process has broken the twenty-foot straight stick limit for electropolished tubing. We provide a consistent electropolished surface on tubes up to 300 feet / 100 meters long - ideal for use in critical analyzer systems.

O’Brien Analytical’s unyielding commitment to quality is evident in every step of our manufacturing process. TrueTube® EP is inspected by O’Brien’s highly trained inspectors, and produced in accordance with an ISO 9001 registered quality system. All TrueTube EP is inspected, cleaned, packaged and always delivered on-time to you.
