Flexitex Extra/Köper
Mandals Flexitex Extra/Köper are made from a blend of nitrile rubber and PVC, with added UV barrier to prevent damage from UV radiation.
The rubber blend is extruded through a circular woven reinforcement made from filament polyester yarn. This production method gives a very strong bonding between cover and lining as well as firmly encapsulating the reinforcing polyester.
Mandals Flexitex Extra/Köper have high resistance against commonly used chemicals. Because of the interlocking circular weave, the hoses do not stretch when pulled. For the same reason, they have a very high pressure rating to wall thickness ratio.
They can operate from -30°C to +75°C. Intermittent use up to +80°C.
The hoses can be delivered in lengths up to 200 meters.
