PTFE polytetrauoroethylene tubing PTFEN
Special requirements
Pressure resistant…
… at 6 bar and 130°C. To ensure
that your systems operate safely,
the test factor is made up of four
times the required safety.
Heat resistant…
… even at ambient temperatures
of 150°C.
Resistant to chemicals…
... this applies to almost all che-
micals.
Ideal for the food industry…
… FDA compliant, TSE free and
hydrolysis resistant.
Easy to clean and robust...
… suitable for any application.
The extremely smooth surface of
the PTFE prevents microbes and
other active agents and contami-
nants from sticking to it, making
it easier for you to clean.
The best choice – thanks to
expert know-how.
Our tested tubing/tting combi-
nations match each other per-
fectly. We always recommend a
combination that precisely suits
your application.
Process reliability is built in with the PTFE thanks to its material
properties. It withstands even the most extreme environmental
inuences and operating conditions. This all-rounder meets the
requirements of the chemical, pharmaceutical, cosmetics and food
industries without any problems. It is resistant to temperatures,
pressure and chemicals, is FDA compliant and is not affected by
atmospheric conditions.
