| Branding | ALFAGOMMA - ITALY 74S 85 BAR (1275 PSI) W. P. HEAVY DUTY CONCRETE PUMPING (in yellow layline with black 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. |
