advantages

High‑pressure steel‑wire braided structure with strong pressure resistance, withstand frequent pressure shock during bulldozer operation and reduce hose‑burst risk
Oil‑resistant inner rubber layer against hydraulic‑oil corrosion; wear‑resistant & anti‑aging outer layer resists gravel scratch, sunlight and rain erosion
Total hose length and joint specification fully conform to OEM parts, no on‑site cutting or crimping required for direct installation
Good fatigue‑resistance for bulldozer high‑frequency vibration condition, reduce premature failure caused by repeated bending

FAQ

Q: Can hose keep working with slight surface crack without oil leakage?
A: Rubber crack means steel‑wire layer has begun aging. Sudden hose burst may occur under heavy‑load shock, replacement is recommended.
Q: Can hose be pulled forcibly to change installation route?
A: Forcible pulling is forbidden. Continuous internal stress will accelerate hose damage under vibration condition.
