DS1 ultra

Steam wire - 18/55 bar - EN ISO 6134 2A



For the use of saturated steam and hot water in the chemical and petrochemical industry, as well as in plant engineering, the construction industry and shipbuilding.


The DS1 ultra is designed for highest demands in industry. Two braids of zinc-plated steel-wire offer best resistance to superheated steam (up to + 230 ° C) and prevents corrosion.

DS1 ultra is characterized by a high flexibility, small bending radius and small bending force as well.

Electrically conductive: Resistance R<106 Ohm.


EN ISO 6134:2017 Type 2, class A.

Temperature range

-40°C / +210°C (saturated steam), peak +230°C (super heated steam); +120°C (hot water).

Safety factor

Steam 10 : 1, Hot water 3,15 : 1
