Sievert high pressure hoses for soldering conform to several standards. Sievert hoses are also extra frost resistant and can be used in temperatures down to -30ºC. The Sievert hose is designed with an inner layer of black gas resistant rubber, a middle layer of reinforcing weave to withstand high pressure and an outer orange coloured layer to protect against external damage, sunlight and ozone.

As a rule, the working pressure for soldering devices is between 1.5 and 2 bar.
