Orange Color Teflon Fep Tubing

Orange Color Teflon 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 400º F), its chemical and dielectric properties are similar to those of PTFE.

Product Description

Orange Color TEFLON Fep Tubing KXT FEP1125

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 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.

FEP Tubing comes in a wide range of standard sizes and custom sizes are available upon request. FEP Tubing is also available in coiled tubing that can be ordered in various sizes, lengths, special sizes and colors to meet your needs.
