FEP Tubing (Fluorinated Ethylene Propylene) is the preferred material in the 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 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.
FEP Tubing Offers:
FEP Tubing Applications:
Aerospace & Transportation Technology, Electronics, Components & Insulators, Chemical & Pharmaceutical Manufacturing, Food Processing, Environmental Sciences, Air Sampling, Fluid Transfer Devices, and Water Processing Systems.

* This tubing has a safety factor of 5 to 1 (ratio of burst pressure to working pressure). This data is to be used as a guideline only. You should perform actual tests according to your specific application.
+ The following equation is for calculating burst pressure. The result from this equation is to be used as a guideline only. The calculation is at ambient room temperature. It does not factor steam pressure, altitude, etc.
B=Burst Pressure
T=Tensile Strength Values: FEP-3000 psi PFA - 4000 psi PTFE - 2500 psi PVDF - 5000 psi ETFE - 6500 psi
1 bar = 14.504 ps
