Product Description:
Grayline FEP tubing is made from a semi-rigid, natural color FDA-approved fluoropolymer resin. It has great gas and vapor permeability properties and is chemically inert. It also exhibits great electrical and weathering properties and has an excellent UV transmission rating. Grayline FEP 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
