BPE SF1 TUBING
Overview
A270 SF1 Polished Sanitary Tubing is manufactured with a controlled mechanical polish on the interior and exterior surfaces, producing a cleaner, smoother finish than standard mill polish but not as refined as electropolished SF4. Ideal for hygienic applications requiring excellent cleanability, consistent surface finish, and compatibility with Tri-Clamp fittings.
