Material construction

Jacket lining:

High-tenacity polyester yarn, circular woven
Specially designed for high compressive strength and tight bending radii
Totally embedded in the polyurethane, offering optimum protection against mechanical damage
No opportunity for microbe or bacteria growth

Lining and jacket:

Special drinking water-safe polyurethane, extruded through the weave in a one-step production process
Highly resistant to abrasion, 10 times longer service life than coated hoses
Inside: Very smooth for minimal pressure loss, easy to clean and disinfect
Outside: Very smooth for good flexibility

Advantages

Extremely tough, hard-wearing and durable
Easy to clean and disinfect, no drying needed
Excellent resistance to all standard disinfectants
Resistant to aging and ozone
Space-saving and easy to use compared to PE or metal pipes
Stays flexible at cold temperatures

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.

Maximum working pressure:

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