Q10. What are the key factors to consider when selecting a hydraulic hose?
A: When choosing a hydraulic hose, consider pressure rating, temperature range, fluid compatibility, size (ID/OD),
flexibility, and abrasion resistance. The hose must withstand the system's maximum operating pressure (including surges)
and be compatible with the hydraulic fluid to prevent degradation. Environmental factors like UV exposure, extreme
temperatures, and abrasion risks also influence selection. Always refer to SAE, EN, or ISO standards for compliance.
Q11. How often should hydraulic hoses be inspected and replaced?
A: Hydraulic hoses should be inspected regularly (at least every 3-6 months) for cracks, leaks, abrasions, bulges, or soft spots.
Replace hoses immediately if damage is found or if they exceed the manufacturer's recommended service life (typically 5-7 years).
Proactive replacement prevents catastrophic failures, which can lead to downtime, safety hazards, and costly repairs.
