Tubes
– Various materials for different applications
– Broad range of colours (e.g. for identifying different mediums)
PU-Polyurethane
– Classic pneumatic tube on polyester basis
– High pressure-resistance
– Good aging characteristics
– Flexible
– Good resilience
– Good tear resistance
– High abrasion resistance
– Good cold flexibility

Applications
Pneumatics
Resistant to aliphatic hydrocarbons and
many lubricating oils,
non-ageing in oxygen and ozone,
drag chain-suitable
Note: PU tubes should not come into direct contact with electric cables as flame retardants used here have detrimental effects on the PU material
