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.

Steel Cord Reinforcement - Provides extended service life in heavy duty applications such as concrete placement, tunneling and piling rigs.

Abrasion Resistant Tube & 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.
