7. FAQ

Q1: What is the difference between a 2-wire braid and a spiral wire hose for 4000 psi applications?

A: For a 4000 psi hydraulic hose, spiral wire construction (typically 4 or 6 spiral layers) is standard. Spiral hoses offer superior impulse fatigue resistance and flexibility under high pressure compared to braided hoses, which are generally rated for lower pressures. Our 4000 psi hoses use multiple spiral steel wire reinforcement.

Q2: Can this hose be used with water-based fluids (HFA, HFB) or phosphate esters?

A: The standard tube is compatible with petroleum-based hydraulic oils and fuels. For water-based fluids, fire-resistant fluids, or specific chemicals like phosphate esters, a special tube compound (e.g., EPDM) is required. Please consult our technical team for fluid compatibility before ordering.

Q3: How do I ensure I order the correct hose assembly?

A: You will need to specify: 1) Hose Type (e.g., SAE 100R13), 2) Inner Diameter, 3) Cut Length, and 4) Fitting Types & Threads on each end. Providing equipment model numbers or old sample hoses can also help us ensure accuracy.

Q4: What is the typical lead time for custom assemblies?

A: For standard configurations, lead time is typically 7-14 days. For large volume orders or special fittings, we will provide a precise timeline upon quotation. We prioritize efficient production to meet your project schedules.

Q5: Do you provide testing certificates with the products?

A: Yes. We can provide standard manufacturer's test certificates. For specific project requirements, additional certification like ISO 9001 or material traceability can be arranged upon request.
