OSW UNIDUR DRAGON
Forest fire hose
Advantages
- Excellent heat and flame resistance → Perfectly suited for fighting forest fires
- High abrasion resistance and durability thanks to longitudinal ribs → Easy to repair if the outer cover is damaged
- Extremely resistant to ageing, ozone and UV radiation
- Suitable for seawater, hot water, oil, petrol and many chemicals
Hose Construction
- Inside: very smooth for minimum pressure loss, fabric made of 100 % high-strength synthetic polyester yarn, circular woven, embedded in the rubber coating, thus optimum protection of the pressure carrier, special flame retardant mixture made of high-quality nitrile/PVC is pressed through the fabric in an extrusion process (standard colour: orange; others on request)
