A wire braided hose consists of crossing and woven high tensile steel wires overlapping one another to reinforce the tube below. Wire braiding machines perform a complex task of winding the wire intricately around the tube, like dancers around a horizontal maypole. The overlapping nature of braided wire not only increases burst resistance to the tube but also allows flexibility between the braids. The crisscrossing braided wire has more tensile play than a spiral hose, resulting in tighter bend radius and overall flexibility.
Applications: It is suitable for the transportation of water-based, petroleum-based hydraulic oil and biodegradable hydraulic oil in harsh working environments such as excavators and other construction machinery, construction machinery, mining machinery and agricultural machinery.
Tube: CR/NBR synthetic rubber
Reinforcement: braided high tensile super fexible steel wire, one braid impulse reaches 300,000 cycles, two braids reaches 600,000 cycles
OuterLayer: skiving-free black smooth hose cover made of anti aging synthetic rubber
Low bending radius: 30% lower than SAE/DIN standards
High pressure: 30% higher than SAE/DIN standards
Long service life: weather resistant for more than 5 years and warrantied for 2years (with Letone specific hoseconnectors)
