Applicable Scenarios

It is mostly used for hydraulic pipeline positions with vibration and swing on loaders, matched with boom cylinder, bucket cylinder, pilot control valve and other hydraulic components. Widely used in long-time continuous operation scenarios such as mines, sand yards, construction sites and cargo yards.

• Original dimension replication, length, fitting angle and thread specification consistent with original machine for direct installation
• Multi-layer steel wire reinforcement structure, resist pulse high pressure with stable pressure bearing, not easy to bulge or burst
• Oil-resistant and anti-aging rubber material with wear-resistant outer cover, reduce premature damage caused by gravel scratch
• Firm and uniform crimping of fittings with reliable sealing, reduce the probability of slow seepage and dripping failure
• Pressure test for each piece before delivery, defective parts screened in advance, stable quality and less after-sales trouble
• Flexible hose structure, adapt to component swing displacement, absorb vibration and relieve connection stress of hard pipes
• Suitable for harsh outdoor working conditions, convenient stock preparation and shorten equipment downtime

FAQ 

Q：Can the hose be used continuously if there are fine cracks on outer cover?
A：Surface cracks are aging signs. It is not recommended for heavy-duty work. Cracks will spread inward and cause sudden burst and oil leakage under high pressure, replace it timely.

Q：What is the requirement of bending radius during hose installation?
A：Do not be smaller than the minimum bending radius of the hose. Sharp folding is forbidden to prevent damage to steel wire layer and service life reduction.

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

Q：Does oil leakage of hose assembly always mean hose body damage?
A：Not necessarily. It may also be caused by aging sealing ring, loose bolts or impurities on sealing surface. Check seals and tightness first before judging hose damage.

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

Q：What should be noticed for storing spare hose assemblies?
A：Store in cool and dry warehouse, avoid direct sunlight, extrusion and sharp bending. Protect pipe ends to prevent dust and impurities entering.
