Danfoss is excited to introduce GH681, a new high performing one wire braided hose qualified to 1 Million impulse cycles. Impulse cycles are a key measure in the life expectancy and overall quality of a hydraulic hose. Standard EN857 Type 1SC hoses are only qualified to 200,000 cycles. Exceeding the standard by 5X means this hose was designed to last and withstand the toughest applications.
GH681 also exceeds the 1SC pressure ratings which extends the range in which hydraulic systems this hose can be used in. See below for some typical applications.
Tube: Synthetic rubber
Reinforcement: Single wire braid
Cover: DURA-TUFF™ synthetic rubber
