Material construction

Jacket lining:

Warp: High-tenacity polyester
Weft: Polyamide; circular woven
The special jacket construction ensures outstanding adhesion and much lower pressure loss compared to a 100% polyester jacket lining
Totally embedded in the reinforced rubber, offering optimum protection against mechanical damage

Rubberized lining and jacket:

Very high-grade NBR/PVC compound, extruded through the weave in a special one-step production process
Special additives in the compound guarantee outstanding resistance to aging and ozone
Inside: Very smooth for minimal pressure loss
Outside: Ribbed for excellent abrasion resistance, protection against contact heat

Advantages

Highly resistant to abrasion, tough and durable
Resistant to oil, gasoline and chemicals (see resistance table)
Resistant to heat, aging and ozone
Very low pressure loss and minimal elongation
Very lightweight, flexible and pressure-resistant compared to mandrel-wound industrial hoses
No cleaning or drying required

Pressures

Working pressure:

Specifications apply only to the hose (medium water, 20 °C). The potential working pressure may be lower than specified above for hose lines with couplings due to the nominal pressure of the couplings or the type of assembly. For compressed air, the maximum working pressure is 25% of the burst pressure.

Maximum working pressure:

Approval can only be given by the manufacturer upon clarification of the exact area of application.
