Bright Annealed Tubing

The FITOK TBA Series is designed for high and ultra high purity fluid systems, especially in the semiconductor industry. Each tube combines high quality materials, controlled manufacturing processes and strict cleaning and packaging standards, eliminating contaminants and ensuring maximum performance and reliability in critical valves, fittings and tubing systems.

The manufacturing process includes cold working of the internal surface followed by bright annealing, achieving internal roughness down to Ra ≤ 0.51 μm (20 μin). Each tube is visually inspected, roughness-measured, and tested for particles, dew point and oil content, then cleaned in an ISO 4 cleanroom with high purity nitrogen, ensuring integrity and cleanliness from the factory to installation.

Tubes come with capped ends, packed in an individual polyethylene bag, marked with brand, material grade, specification and heat number, and are available in standard lengths of 2, 3, 4, 6 m and 20 ft.
