Rubber EPDM, AEM, NBR & HNBR hoses
Black rubber hoses and hoses for cooling and heating in theautomotive and agricultural industries DARWIN PLUS“DARWIN PLUS” are made from a high-quality rubber compound based on EPDM, AEM, NBR and HNBR rubber, depending on the operating temperature and the operatingmedium.
The outer casing of the hoses is resistant to coolant fluids, ozone, climatic effects, sunlight, and ambient temperature.
Working medium: Coolant, air, hot air with oil vapors, oil, motor oils, mineral oils, diesel fuel & gasoline.

Material: Rubber compound based on
- EPDM (Ethylene Propylene Diene Monomer rubber)
- AEM (Ethylene Acrylic rubber)
- NBR (Nitrile-butadiene Rubber)
- HNBR (Hydrogenated Nitrile Butadiene Rubber) Working pressure 0,4 MPa (for diameters up to Ø 40 mm), 0,2MPa (for diameters more than Ø 40 mm).
The maximum value of the negative pressure of the working medium upto 0,01 MPa.
Burst pressure pb: 2 x Working pressure.
Reinforcement - Polyester thread.
Wall thickness from 4 to 7mm depending on inner diameter and working pressure.
Surface: Glossy finish, Matte finish, Color black.
ADVANTAGES
- Highly elastic rubber (hardness range from 40 to 90 Shore A)
- The increased thickness prevents cold water leakage and
curing at low temperatures Heat resistance
- Resistant to coolants, ozone and surrounding
