FEP Tubing (Fluorinated Ethylene Propylene) is the preferred material in production of small diameter tubing of continuous lengths. While some temperature resistance is sacrificed with FEP (to 204ºC/400º F), its chemical and dielectric properties are similar to those of PTFE. FEP tubing is a clear tubing that is an economical choice for applications requiring chemical resistance and a broad temperature exposure. FEP Tubing offers excellent clarity which makes it ideal for sight glass/flow monitoring applications. FEP Tubing has a slightly higher coefficient of friction, lower continuous service temperature, and is more transparent then PTFE. FEP Tubing also has better gas and vapor permeability properties and excellent UV transmission ratings.
