PTFE Hose - Overview

Smooth Bore PTFE hose is capable of carrying a wide range of difficult-to-handle media such as chemicals, steam, solvents, inks and dyes, paint, injectable materials and plastisols.

It is used for a variety of applications such as sanitary transfer, bottle filling, gas analysis, extrusion presses and molding/adhesive conveying.

The temperature ratings for this king of hose are quite broad: -65°F to 450°F.

PTFE smooth bore hose is kink resistant with improved vacuum ratings and damage resistance. It cleans easily with steam, detergent or caustic and can be autoclaved.

Advantages of PTFE

Chemical Resistant:
PTFE creates a virtually universal hose which handles the broadest range of media.

Temperature Resistant:
From cryogenics to steam all in one hose.

Low Friction:
Low pressure drop because deposits do not accumulate on the Inner core. Easy to clean permitting use of one hose for several services.

Withstands continuous flexing and vibration without failure from flex fatigue.

Moisture Resistant:
Ideal for pneumatic systems requiring low dew point functionality.

Chemically Inert:
Will not break down or deteriorate in service.

Unlimited shelf life because properties do not change with age or exposure to weather.

PTFE Hose Characteristics
  • Tensile strength 3,500 psi
  • Elongation 250% min
  • Dielectric Strength 1,000 volts per mil
  • Softening point 500F (260C)
Polytetrafluoroethylene is an engineered fluoropolymer commonly known by DuPont's trade name "Teflon". Outstanding resistance to chemicals is one of it's primary attributes. A broad temperature range of -100F to 500F (-73C to 260C) make this hose material suitable for the majority of fluid and ambient temperature conditions found in industry. An extremely low coefficient of friction, (0.05 to 0.20), provides a non-stick surface. Water absorption of PTFE is negligible, less than 0.01% by ASTM test. And, it is FDA-approved for food and pharmaceutical use.
