Features and Advantages

Features and Advantages

 N/A
  • Heavy Duty Construction – Durable, thick walled construction, resists kinking, elongation and vibration during operation. All sizes rated to working pressure of 1275 PSI with 2:1 safety factor.
  • Textile Yarn Reinforcement – Operator friendly, lighter weight versus wire reinforced hoses for easier handling while still providing extended service life in heavy-duty applications.
  • Abrasion Resistant Tube and Cover – The NR (natural rubber) tube resists the wear caused by the flow of abrasive concrete. The SBR/NR blend cover resists the wear caused by dragging over rough surfaces, as well as environmental (UV/ozone) damage.
  • Cold Flex Materials – Hose remains flexible in sub-zero temperatures.
