Tetron PTFE & FEP Tube

PTFE Product Description

TETRON PTFE FEP Tubing offers an unmatched balance of properties making it useful for a variety of harsh service uses.

Why two types of tubing?
FEP offers benefits that re currently unavailable with PTFE. It can be produced in practically unlimited continuous lengths, reducing waste. It has much greater clarity than PTFE and has been found to be superior in cryogenic service.

Key Features and Benefits:
Chemical: Lite PTFE, FEP tubing is chemically inert to essentially all industrial chemicals and solvents, even at elevated temperatures and pressures. However, it reacts with fluorine, molten alkali metals and molten sodium hydroxide. FEP absorbs practically no common acids or bases at temperatures of 200 C, for 12 months exposure.

Zero Moisture Absorption:
No swelling or change in properties due to moisture absorption.

Indefinite Shelf Life:
The outstanding aging resistance of PTFE and FEP prevents embrittlement with age.

Low Friction:
The inherent slipperiness of PTFE and FEP make assembly quick and easy.

Does not smoke or support combustion. 


PTFE Availability:
Tetron PTFE tubing is available in over 100 sizes ranging from 0.30mm I/D to 28.0mm O/D and wall thicknesses from 0.15mm to 1.5mm. Tetron PTFE and FEP tubing are also available in colours and metric sizes on request.

Typical PTFE Applications:

Harnessing: Hold several cables together in high temperature environment, insulating cable sheave.

Slip on Insulation:
The flexibility and slipperiness of Tetron PTFE and FEP tubing permits it to be readily slipped on primary conductors or fuses as insulators.

Fluid Handling:
Corrosives - Almost universally inert.
Sticky Materials - Paint, adhesives, chocolate, molasses, etc, without clogging.
Paint Spray Equipment - Clean up easily by circulating chemical cleaner or steam clean when changing colours.
Sample Collection Equipment - Eliminates contamination.
Medical Tubing - Cap be easily sterilized either by heat or chemicals.
