Material construction

Jacket:

High-tenacity polyester yarn, circular woven in twill weave (much more resistant to abrasion than plain weave)
2-ply warp threads, lightweight, tough and flexible

Lining:

High-grade EPDM rubber, flexible at low temperatures, also suitable for hot water, wall thickness 0.8 mm
Excellent resistance to seawater, chemicals, UV radiation and ozone (much better than SBR, for example)
Co-extruded adhesive layer (0.2 mm wall thickness), penetrates the weave almost completely during vulcanization
This type of rubber guarantees a very smooth lining with low friction loss and excellent adhesion between the rubber and jacket

Outer coating:

Highly abrasion-resistant synthetic coating for better resistance against heat, oil and chemicals
Extra mechanical protection against jacket damage

Advantages

Very lightweight and highly flexible (also at extremely low temperatures)
Excellent resistance to heat, aging and ozone
Lining extremely resistant to seawater and a wide range of chemicals (see resistance table)
Tough and durable
Resistant to mildew and rot
Easy to repair

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.
