Teflon Tubings

Teflon TFE Tubings

TFE Teflon tubings are the most versatile insulating materials offering highly stable electrical, chemical and mechanical properties at virtually all electronic frequencies throughout an operating temperature range of -70°C to 260°C. 

TFE Teflon tubings are non-toxic and will not burn in normal atmospheres at any temperature and are inert to practically all lubricants, solvents, and reagents. Electrical performance is superb, offering extremely high dielectric strength in the thinnest cross-sections, with hot soldering irons and subzero environmental conditions having equally no effect. 

TFE Teflon tubings possess the lowest coefficients of friction of any known solid. They are also immune to wicking, moisture absorption, or contamination from objectionable sources. The anti-stick characteristic facilities use in applications where space is limited, fits are tight, or lengths are long. 

TFE Teflon tubing is the material to specify when the reliability and dependability of an application at environmental, electrical, mechanical, and chemical extremes is paramount.

Consider using TFE tubings where:

Insulation may be damaged by hot soldering irons, near substances that   must not be contaminated: IC Production, Pharmaceuticals, Photographic Chemicals, Foods & Beverages, Aerospace Materials, Medical Supplies & Equipment, Clean Room Environments.

With or near corrosive substances such as strong acids and alkalis or where insulation may come into contact with greases, oils, fuels, solvents, missile propellants or other industrial chemicals.

Where lowest possible static friction is desired.

Where tubing must be anti-stick and easy to clean.

Where a material that will not support combustion in normal environments is required.

Where tubing must function at extremely high or low temperatures.

In applications calling for low loss, stable, long term electrical properties, especially at high frequencies.

In locations subject to weathering.

Where weight saving is essential.

In high humidity locations where there is a tendency for environmental attack. 

In compact assemblies where thin walls are required.

In fluidic control systems.

In automotive, aviation and marine equipment.
