Typical settings include semiconductor fabrication, pharmaceutical and biotech, and aggressive-media pipelines.
Stocked as TFE269 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
