CONSTRUCTION
- Tube – Black conductive NR – abrasion resistant
- Reinforcement – High tensile textile cords
- Cover – Black conductive SBR/NR blend – abrasion and ozone resistant
WORKING PRESSURE
1275 PSI
SERVICE TEMPERATURE RANGE
-22°F (-30°C) to +176°F (+80°C)
BRANDING
ALFAGOMMA – ITALY T74S 85 BAR (1275 PSI) W. P. HEAVY DUTY CONCRETE PUMPING (in yellow letters)
FEATURES AND ADVANTAGES
- 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.
