• Premium oil-resistant synthetic rubber inner tube, excellent compatibility with hydraulic oil, not easy to swell or degrade.
• Multi-layer high tensile steel wire braid structure, outstanding pressure resistance, resist sudden pressure surge.
• Thick wear-resistant outer rubber cover, good anti-ozone and anti-UV performance, extend service life outdoors.
• Professional integrated crimping between hose and steel fittings, high pull-off resistance, low risk of joint leakage.
• OEM-level dimension and connector specs, fully match original pipeline layout, simple installation and replacement.
• Good flexibility, convenient routing around frame and other components, avoid excessive bending stress.
• Strong vibration resistance, suitable for continuous mechanical vibration of loader during heavy-duty operation.

FAQ 

Q1：What signs mean the hose assembly needs replacement?
A1：Hose surface crack, oil seepage at crimp joint, outer rubber peeling, hose bulging under pressure, frequent oil leakage.

Q2：What should be noted during hose assembly installation?
A2：Avoid sharp bending and twisting; keep away from sharp metal edges and high-temperature exhaust parts; fix with hose clamps properly, check leakage after pressure test.

Q3：What are common causes of hose assembly damage?
A3：Abrasion from gravel; over-bending installation; high temperature aging; excessive pressure impact; outer rubber damaged by sharp objects.

Q4：Can leaking hose be repaired?
A4：Not recommended. Once the rubber hose or steel wire layer is damaged, repair cannot restore original pressure resistance. Better install new hose assembly directly.

Q5：How to inspect hose assembly during daily maintenance?
A5：Check hose surface for cracks, blisters and oil seepage, inspect outer rubber wear condition before heavy load work.

Q6：What failures will a failed hose assembly cause?
A6：Hydraulic oil leakage will lead to pressure loss, loader lifting and steering action weak. Serious burst may cause sudden loss of hydraulic power and safety risks.
