As metal designs they are flexible yet pressure-resistant and offer high temperature stability from −10 °C to +500 °C; they therefore belong to the group of heat-resistant stainless-steel hoses. They also provide corrosion protection and torsional stiffness.
Stainless-steel pressure hose assemblies with threaded fittings are annularly corrugated hoses made of 1.4404 with single braid; one end fitted with a hex nipple (male thread), the other with a cone-sealing fitting made of 1.4571. Temperature range −10 °C to +300 °C; thus classed as heat-resistant hose assemblies. Max. operating pressure 25 bar at +20 °C for all types.
Stainless-steel vacuum hoses with small-flange connections are classed as heat-resistant hoses; they are annularly corrugated stainless-steel types per DIN 14541 (German standard for corrugated metal hoses; no direct ISO equivalent, EU usage). Temperature range −10 °C to +550 °C, identifying them as heat-resistant metal hoses. Vacuum integrity is verified by helium leak testing at a leak rate < 10⁻⁹ mbar/L/s.
