Product Description:
Grayline PTFE (commonly referred to as Teflon®) tubing is made from a semi-rigid, natural color FDA-approved fluoropolymer resin. It exhibits great electrical and weathering properties and offers excellent aging resistance. Grayline PTFE tubing can be used with virtually all industrial solvents, chemicals, and corrosive materials, even at elevated temperatures (excluding fluorine, molten sodium hydroxide, and molten alkali metals). It can be steam or chemically sterilized in-line with any industrial cleaner, solvent, or sterilizing method. It’s non-stick property allows transport of viscous, sticky materials without line clogging.
