PTFE hose with permeation-resistant features:Smooth-bore PTFE core.Commonly used where chemical compatibility and permeation resistance is desired.Standard and custom assemblies available.
The PTFE Advantage
PTFE hose is ideally suited for applications requiring maximum flexibility, high-pressure ratings, chemical and temperature resistance, and extremely long life. PTFE hose offers the following advantages:
Flexible–The flexibility of PTFE hose provides excellent resistance to failure in fatigue and flexing applications.
Chemical Resistant–PTFE is inert, thus creating a nearly “universal” hose capable of handling the broadest range of applications.
Temperature Resistant–It even handles steam–up to +388°F.
Non-Stick–PTFE hose is easily cleaned to maintain batch purity when using one hose for several services.
Low Friction–PTFE hose exhibits low-pressure drop that remains constant because no deposits accumulate on the inside wall of the hose.
Moisture Resistant–Ideal for pneumatic systems requiring low dew point.
Non-Aging–Properties of PTFE hose do not change with age or exposure to weather.
Example of PTFE Applications
Molding–PTFE hose handles steam up to 388°F @ 200 psi steam pressure for heating of plastic and rubber molding presses.
Urethane Foam Manufacturing–PTFE hose handles isocynates and other activators at the high pressures in foam manufacturing processes.
Gas Transfer/Breathing Apparatus–PTFE hose exhibits low permeability to 02, N 2, & Argon under high pressure.
Marine Hydraulic Control & Power Systems–PTFE hose is resistant to fire resistant and water emulsion hydraulic fluids used in marine systems.
Steam Applications–PTFE hose is ideal for use on heating lines on dryers in processing plants and as lines that provide steam to laundry garment presses.
Fuel Lines–PTFE, when used as a fuel hose, is resistant to the blending of additives in fuels.
Compressor Discharge Hose–With most compressor discharge applications operating above 300°F, PTFE hose is the obvious choice over rubber hose. Less carbon particles deposit on PTFE due to its inherent release properties.
Chemical Handling–PTFE hose solves chemical handling problems – whether its low permeability or low buildup–in leading stations, on flexible connections between chemical pipework, and in laboratories.
Adhesives–PTFE hose handles the adhesives that are present in shoe manufacturing, canning operations, and carbon manufacturing.
