Information about hose materials
The standard hose in Norprene has excellent mechanical properties with high chemical resistance to many substances.
Marprene offers a long life for many applications with high chemical resistance, particularly when oxidation agents are present.
This is therefore the first alternative to the standard Norprene hose.
Fluran is particularly beneficial if the condensate contains oils, petrols and other solvents. The mechanical properties should
rather be assessed weaker, so we only recommend this hose material for the specified chemicals.
The flow capacity of Fluran and Marprene hoses is slightly lower.
Other materials are available on request.
