FEP Fluoropolymer Tubing
FEP (Fluorinated Ethylene Propylene) tubing is transparent and can be heat-sealed and heat-bonded. FEP resin is pelletized for its hot-melt extrusion process. FEP tubing is known for its gas and vapor permeability properties and excellent UV transmission ratings. While very similar in composition to PTFE, there are a few notable differences. FEP has a lower heat shrink temperature and is clearer and more flexible than PTFE.
Almost totally inert, Fluoropolymer tubing can be used with virtually all industrial solvents, chemicals, and corrosive materials, even at elevated temperatures. It does, however, react with fluorine, molten sodium hydroxide, and molten alkali metals.
Fluoropolymer tubing can be steam or chemically sterilized in-line with any industrial cleaner, solvent, or sterilizing method.
Fluoropolymer’s non-stick property allows transport of viscous, sticky materials without line clogging. It also offers outstanding aging resistance.
Permanent color striping, etching, and longer-than-listed lengths are available through minimum order. Polyethylene-jacketed, thin-wall fluoropolymer tubing, for low-cost purity, is also available through minimum order — call for details.

NOTE: Values listed are typical for the material used in manufacture, except where noted, and are meant only as a guide to aid in design. Field testing should be performed to find the actual values for your application.
Cut Pieces – When tubing comes in, for example, 100 foot coils, and you need it in 10’ sections, tubing can be cut. Request a quote.
Size – Tubing is stocked in common I.D. and O.D. sizes, but this product can be custom extruded in other sizes. Let’s talk about what you need. Minimum quantities apply.
Color – Have your tubing colored to match equipment, company colors, or identify line (hot or cold, indoor or outdoor, chemicals, etc..).
Opaque and transparent colors may be accommodated. Minimum quantities apply.
All custom products are subject to minimum order quantities and lead times. For other custom options, please contact us.
