-
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.
