Application Scenarios

It is used for flexible connection of hydraulic circuits and cooling circuits of wheel loaders, widely used in earthwork, quarry, sand yard, bulk material loading and other heavy vibration working conditions.

• Produced in accordance with OEM specifications, length, inner diameter and joint size fully match original assembly, can be installed directly without modification.
• Multi-layer composite structure, stable pressure resistance, can withstand frequent pressure fluctuation impact in hydraulic system.
• Good flexibility and reasonable bending radius, easy layout, avoid hard bending and sharp folding during installation.
• Outer rubber layer with excellent wear and aging resistance, effectively resist mud, friction and outdoor sun exposure.
• Good compatibility with hydraulic oil, the inner rubber will not easily swell, harden or crack for a long time.
• Can absorb vibration and buffer displacement between parts, reduce fatigue fracture risk of pipeline system.
• Strict pressure and bending fatigue test before delivery, stable quality and long service life under normal use.

FAQ 

Q1: Can this hose be interchanged with other hoses of different part numbers?
A1: No. Different part numbers differ in length, pressure rating and connection size. Please select the hose with the same part number.

Q2: What are the common reasons for hose leakage?
A2: Aging of rubber, surface abrasion, inner layer damage by impurities, over-bending, excessive pressure and loose clamp are the main causes of leakage.

Q3: What should I pay attention to when installing the hose?
A3: Avoid sharp bending and twisting. Reserve enough slack to accommodate vibration. Keep away from high-temperature exhaust parts and sharp edges.

Q4: Can the leaking hose be repaired on site?
A4: Rubber hoses cannot be reliably repaired. Once damaged, it must be replaced directly to prevent sudden burst during operation.

Q5: How to judge whether the hose needs to be replaced?
A5: Replace it if you see cracks, blistering, oil seepage, hardening, serious wear or bulge deformation on the hose surface.

Q6: What will happen if the hose is too tight with no allowance?
A6: No slack will make the hose bear tensile force under vibration, accelerate fatigue and lead to early rupture.
