GH HERKULES 2F

H2F

Coated fire and industrial hose

Applications

  • Fire brigades
  • Industry
  • Shipping
  • Military
  • Disaster relief
  • Construction
  • Agriculture

Features

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

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, suitable also for hot water, wall thickness 0.8 mm
  • Excellent resistance to seawater, chemicals, UV radiation and ozone (much better than e.g. SBR)
  • Co-extruded adhesive layer (0.2 mm wall thickness), penetrates during vulcanisation almost completely into the weaving structure
  • 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

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.
