* Temperature correction for T 1 – 4 100°C x 0.9; 200°C x 0.8; 250°C x 0.6;
It is essential that you note the minimum bending radius, since if this
is exceeded this will cause the pressure hose to leak thus making the
complete heating hose unusable, respectively no longer repairable.
We accept no liability for such damage.
The hoses of polytetrafl uoroethylene PTFE (Tefl on™) can be univer-
sally employed in a range from -70°C to +250°C, and are charac-
terised by their unusual chemical stability; they are only unstable in
the presence of fl uorine compounds, as well as the alkaline metals
sodium or potassium and halogens.

two braided layers of stainless steel wire, (1.4301), max. working
temperature 600°C

* working pressure bar 176 131 93 85 57 65 46 50 35
min. bending radius mm 125 150 170 190 220 250 290 480 550
* Temperature correction for T 5 100°C x 0.8; 200°C x 0.7; 250°C x 0.6;
350°C x 0.55; 500°C x 0.52
Hoses of stainless steel can be employed virtually without limitation
in the range from
-190°C to max. + 600°C for liquid and gaseous media in all in-
dustries, and are completely diffusion resistant; not suitable for
chlorides, bromides and other halogens.
