The Nai-Lok Hastelloy® C276 / C22 / B3 ASTM A269 Electropolished 6N Gas Super Clean Pure Oxygen Tubing is a premium-grade seamless tube designed for ultra-high-purity applications in semiconductor manufacturing, medical gas systems, and high-purity chemical processing.
These tubes are bright annealed, electropolished, and super-cleaned to meet 6N (99.9999%) gas purity standards, ensuring zero contamination in critical environments. Manufactured from Hastelloy ® C276 (UNS N10276), C22 (UNS N06022), and Hastelloy® B3 (UNS N10675), they offer exceptional corrosion resistance, high-temperature stability, and superior surface finish.
Ultra-High Purity (6N Cleanliness) - Meets 99.9999% purity standards for semiconductor and medical gas applications.
Electropolished & Bright Annealed - Smooth internal surface minimizes particle adhesion and gas absorption.
Corrosion-Resistant Hastelloy®s - Hastelloy C276, C22, and Hastelloy® B3 resist acids, chlorides, and oxidizing media.
Seamless Construction - Ensures leak-proof performance in high-pressure systems.
Super Clean & Oxygen-Compatible - Ideal for ultra-pure gas delivery, semiconductor fab tools, and medical oxygen lines.
Compliant with ASTM A269 - Meets industry standards for precision tubing.
