Fluoropolymer lined Hoses meet USP Class VI & FDA criteria with extra thick liners to provide better flex life and less permeation. Anti-static tube options are available. High grade polytetrafluoroethylene (PTFE) resins are used in these over-braid products for extraordinary performance. The unpigmented PTFE liners make these Hoses exceptional for high-purity use in the biotech, pharmaceutical and food processing industries. The interior and exterior of the hose are simple to clean and will not transmit taste or odor to transferred substances. They are designed to meet FDA and USP Class VI standards.
