Is the DUO PU Twin Polyurethane Air Hose – Durable and Flexible Solution suitable for use in robotic and pneumatic systems at temperatures from -40°C to +85°C?

Yes. The DUO PU Twin Polyurethane Air Hose – Durable and Flexible Solution is suitable for use in robotic and pneumatic systems at temperatures from -40°C to +85°C. Its polyurethane construction (Shore hardness 90°A) retains elasticity down to −40°C and performs safely up to +85°C. It is engineered for pneumatic and robotic applications, resists abrasion, solvents, fuels and hydrocarbons, and—depending on diameter—offers working pressures from 12 to 23 bar, making it a durable, flexible, and reliable choice for such systems.

Can the DUO PU Twin Polyurethane Air Hose – Durable and Flexible Solution withstand repeated exposure to oils, fuels, and solvents without degrading its performance?

Yes. The DUO PU Twin Polyurethane Air Hose – Durable and Flexible Solution is engineered to resist oils, fuels and solvents without losing performance. Made from durable polyurethane (PUR) and explicitly stated to withstand abrasion, solvents, fuels and hydrocarbons, it maintains long-term durability in harsh environments. Its 90° (A) Shore hardness provides strength while preserving flexibility down to −40°C and up to +85°C, so chemical exposure combined with temperature extremes won’t readily compromise elasticity or integrity. Additionally, its working pressure range (12–23 bar depending on diameter) and robust construction ensure consistent performance under repeated exposure, making it suitable for pneumatic, hydraulic, tool lines, robotics and mobile equipment where contact with oils, fuels and solvents is expected.
