Applicable Scenarios

It is mostly used for flexible oil circuit connection at hinged moving parts of loaders, matched with hydraulic steel pipes, oil cylinders and multi-way valves. Widely used in continuous vibration and high-frequency working scenarios such as mines, sand yards, construction sites and cargo yards.

• Original specification replication, length, fitting angle and thread match original machine for easy alignment
• Multi-layer steel wire reinforcement structure, resist pulse high pressure, stable pressure bearing, not easy to burst or bulge
• Oil and weather resistant rubber material with wear-resistant outer cover, delay early damage caused by gravel scratch
• Stable crimping process of fittings with reliable sealing, reduce the probability of slow oil seepage
• High pressure test for each piece before delivery, defective parts screened in advance, stable batch quality
• Flexible buffer structure, absorb vibration deformation and eliminate additional stress of hard pipe connection
• Suitable for harsh heavy-load working conditions of loaders, easy stock preparation and reduce maintenance downtime

FAQ 

Q：Can the hose be used continuously if fine cracks appear on the surface?
A：Surface cracks are signs of rubber aging. It is not recommended for heavy-duty operation. Cracks will extend inward and cause sudden burst and oil leakage under high pressure, replace it timely.

Q：What is the requirement for bending radius during hose installation?
A：The bending radius shall not be less than the specified minimum value. Sharp folding and twisting installation are forbidden to avoid damage to inner steel wire and service life reduction.

Q：Can hose assemblies of different part numbers be interchanged?
A：Interchange is not recommended. They differ in length, fitting type and rated pressure. Forced replacement may lead to assembly interference and sealing leakage.

Q：Does oil leakage of hose mean the hose body is damaged?
A：Not necessarily. It may be caused by aged sealing ring, loose bolts or impurities on sealing surface. Check seals and fastening status first.

Q：How to prolong the service life of hydraulic hoses in daily use?
A：Fix pipelines reasonably, keep away from high-temperature exhaust pipe and sharp edges, inspect regularly and avoid long-time over-pressure operation.
