Standard length : 100 m ( 330 ft ) Standard colour : dark blue Service temperature: -10 °C up to +60°C (14°F up to 140°F), based on water Tolerances can be found in the technical appendix Change in technical specification without prior notice 10 Bar = 1 MPa

* technical data based on water at a temperature of 20°C (68°F). Depending on application and dimension of hose this product can be operated with a working pressure up to 50 % of the bursting pressure. Consult factory for approval! It is important to note, that the technical data for pressure are only valid for hose and not for hose assembly with Couplings!

CONSTRUCTION
Textile reinforcement:
• high tenacity polyester yarn, special construction for low elongation • totally embedded in the PVC compound, excellent protected against mechanical damage

ASSEMBLY OF COUPLINGS:
• the hose tail of the coupling should be machined and free of sharp edges to avoid that the inner tube is cut • if hose is binded with clamps a piece of hose should be placed between hose and coupling tail as a protection • the bandwidth of the clamp should be dimensioned in a way, that the hose is not squeezed between the ribs of the hosetail

Lining and cover:
• Special high grade formulated PVC compound extruded “through the weave“ in a unique one step production process • much better adhesion level compared to conventional PVC layflat Hoses, no delamination • inside: very smooth for minimum friction loss • outside: smooth for good flexibility
