The correct selection of hydraulic hoses directly affects system safety and efficiency. Selecting matching hoses according to pressure level, medium type and environmental conditions, and performing regular maintenance can maximize service life.
★ Maintenance and replacement cycle
Daily inspection: cracks in the outer rubber layer, exposed steel wire, oil leakage from the joint
★ Replacement criteria:
"Python pattern" cracks appear on the surface (sign of aging)
Working pressure drops by more than 10%
- Recommended life: 3~5 years (depending on the intensity of use)
