Tubes made of Krülit

Tubes made of epoxy-glass-fabric or silicon-glass-fabric type Krülit® are used in all branches of the electro industry because of their superior mechanic, thermical and electric characteristics. A high shape constancy also in upper temperature spheres makes tight tolerances possible against that in cold spheres type 700 has proved worthvile.

Structure: Tubes made of Krülit 700 or 750 consist of with epoxyresin impregnated glass-fabric-lengths against that we use silicon as resin with type Krülit 800. They are parallel winded on winding machines, where the resin under the influence of warmth and pressure glues together the lengths. At the following hardening process the layers get indissoluble. The finished tubes then get grinded and mechanically worked as the customer wishes.


We can produce the following Krülit®–types.

Krülit 700 Hgw 2375 acc. DIN 7735 EP GC 21 acc. EN 61212
Krülit 704 Hgw 2375.1 acc. DIN 7735 EP GC 23 acc. EN 61212
Krülit 750 Hgw 2375.4 acc. DIN 7735 EP GC 22 acc. EN 61212
Krülit 750-H Hgw 2375.4 acc. DIN 7735 EP GC 22 acc. EN 61212
