Corrugated FEP Tubing
Corrugated FEP Tubing was originally designed by Ira Clement in 1966 at Penn Tube Plastics in Clifton Heights, Pennsylvania.This new tubing was engineered to be a flexible Fluoropolymer tube that can turn sharp corners and be shaped with very small bend diameters without reducing the inside diameter and is crush resistant. First used in bottle filling lines for its compression capability and later in paint solvent machines for its chemical inertnes, Corrugated FEP Tubing became a necessity for fluid handling applications.
Manufactured from FDA compliant FEP and PFA resins corrugated tubing can be used as an electrical or fluid conduit for robots equipped with flexible arms that contain electrical wiring, air, or corrosive liquids and is still safe for food contact. Corrugated Tubing will operate in applications where high temperatures are required and other materials are not suitable. Corrugated FEP Tubing can be reinforced with Kevlar braid, or other textile braids for operations at higher pressures. Fluorinated ethylene propylene or FEP is a high temperature material that has a non-stick surface, allowing easy cleaning and removal of foreign matter in the lines,but does not self drain like convoluted tubing will. FEP is an excellent electrical insulator and is resist most strong corrosive liquids including hot acids. Tef Cap’s Corrugated FEP Tubing is manufactured from USP Class VI virgin FEP resin and is non-contaminating. Corrugated PFA Tubing can also be manufactured in the sizes listed below.

Tef Cap Industries’ Corrugated FEP Tubing is manufactured to extend and compress all without affecting the internal diameter of the tube. This helps eliminate drops in flow rate and increases turbulence for better surface contact in heat exchange applications. Corrugated FEP Tubing has nearly twice the surface area or contact when compared to extruded smooth bore PTFE tube.

Available in a Variety of Sizes and Lengths
With over 50 years of experience as a critical partner, innovator, and supplier of Fluoropolymer Tubing (Teflon) and Fluorinated Ethylene Propylene (FEP) for numerous fluid handling applications across several tech industries, Tef Cap Industries has established itself as the best source for heat shrink FEP tubing.
Our corrugated FEP tubing can be found extensively in the automotive, aerospace, aviation, medical device, electronics, semiconductor, construction, and agricultural industries. From chemical processing applications where protecting against exterior corrosive chemicals and acids is critical to maintaining operations to medical applications where catheters rely on uninterrupted and impenetrable fluid flow, our corrugated FEP tubing is relied upon for its flexibility, durability, and excellent chemical inertness.
As a well-established FEP tubing manufacturer, Tef Fap Industries has made its corrugated FEP tubing available in numerous different sizes and configurations. With an extension compression value of approximately 2 to 1, our FDA-compliant, flexible, and kink-resistant FEP tubing is available from ¼ inch up to ½-inch sizes.
Resistant to Friction, Corrosion, Water, and More!
Protecting your fluids from the elements and contamination is critical, regardless of your fluid application. Our corrugated FEP tubing provides excellent friction resistance while minimizing fluid adhesion. A chemically resistant tubing solution, our corrugated FEP tubing is exceptionally flexible, allowing for applications where tubing must be adjusted or fit into tight-fitting bends and limited spaces.
You’ll find an extremely versatile solution with our corrugated FEP tubing, which can easily fit in the tightest areas without compression, reducing the tubing’s inner diameter.
