FAQs
How long do hydraulic hoses typically last?
Hydraulic hoses typically last between 1–5 years depending on their operating conditions. Factors like pressure spikes, temperature, abrasion, and fluid compatibility significantly affect their lifespan.
How often should I inspect hydraulic hoses?
Inspect hoses every 3 months or after 400–600 operating hours. Look for leaks, visible damage, cracks, or exposed reinforcement. Replace any damaged hoses immediately.
What are common causes of hydraulic hose failures?
Common causes include abrasion damage, incorrect routing (tight bends, twists), pressure spikes, chemical incompatibility, and improper installation. Proper routing, protective sleeves, and regular inspections help avoid these issues.
What factors should I consider when selecting hydraulic hoses?
Select hoses based on pressure rating, hose diameter, temperature compatibility, fluid compatibility, bend radius requirements, and abrasion resistance. Always match hoses with compatible fittings.
How can I improve the durability of hydraulic hoses?
Use correct hose lengths to avoid sharp bends or twists, ensure hoses are routed safely away from abrasive surfaces, and regularly inspect and replace worn hoses promptly. Protective sleeves also extend hose life.
Which fitting type is best for high-pressure mining applications?
High-pressure applications are most suited to ORFS, Code 61 and Code 62 fittings as they use a rubber or soft seal. JIC and BSP connections aren’t recommended for high-pressure applications due to their metal-to-metal sealing design, which can be prone to leakage under extreme pressure conditions.
Can I use field-attachable fittings with all Armadillo hoses?
The short answer is no. Field-attachable fittings should be considered as one-time use only emergency solutions. We call them field-attachable because you don’t need a crimper, but they aren’t reusable and don’t provide the same reliability as properly crimped connections. Field-attachable fittings should only be used with 1-wire and 2-wire hose applications and are not suitable for high-pressure or critical applications.
What's the difference between one-piece and two-piece crimp fittings?
One-piece crimp fittings have the ferrule pre-crimped to the hose tail, which saves assembly time because you simply push the hose to the correct depth and crimp. With two-piece crimp fittings, the ferrule needs to be installed on the hose first, then the hose is inserted and crimped together. The installer must ensure that the ferrule has located on the hose tail correctly, which requires more precision during assembly.
How do I ensure proper fitting compatibility?
You should only use fittings from the same supplier as the hose, as the supplier has already ensured compatibility through rigorous testing and quality control. If you need to mix and match components from different suppliers, consult with the fitting supplier and request the correct crimp specifications and compatibility documentation.
What crimp specifications should I follow?
Only follow crimp specifications supplied by the manufacturer. Using incorrect specifications can result in hose failure, safety hazards, and voided warranties. Proper crimp specifications typically ensure optimal hose performance and can prevent up to 95% of premature hose failures.
