Application: Highly flexible multi-purpose hose, with very good ageing, weather and abrasion resistance. Suitable for conveying air and water, as well as many chemical products in industry and agriculture.
Features: High temperature EPDM ensures excellent ozone & weather resistance. Kink resistant due to textile reinforcement. Electrically conductive tube construction prevents the build-up of static electricity. R < 10E6Ω (according to EN ISO 8031:2009).
Temperature Range: -40°C to +120°C ; max. +100°C fluid temperature in closed systems
Safety Factor: 4 : 1
Branding: “COLORFLEX PN 20 BAR DN +100°C (conditionally +120°C) MADE IN EU"
Notice:
Attention: As temperature increases or decreases, burst pressure, safe working pressure, coupling retention properties and other safety characteristics of the hose can significantly decrease in closed systems/applications. Failure to consider how temperature and other conditions affect hose performance may cause property damage, serious bodily injury or death. The hose must not be used in constantly pressurized closed systems at temperatures >100°C.
Attention: Please refer to the Semperit resistance list or, in case of doubt, contact Semperit.
Attention: The temperature of the medium must be lower than its boiling point.
