Rubber Mixing Tube Extrusion Wire Spiralizing Cover Extrusion Curing & Vulcanization Pressure Testing
  • Rubber Mixing: Advanced Banbury mixers ensure uniform raw material blending for core durability.
  • Tube Extrusion: Continuous CNC extrusion lines enable precise tube wall control (+/- 0.2mm tolerance).
  • Wire Spiralizing: Four spiral high-tensile steel wires are helically wound via automated, tension-monitored machines. This gives EN856 4SP hoses superior pressure rating (>400 bar).
  • Cover Extrusion: Smooth, non-porous outer layer resists abrasion, UV and oil.
  • Curing & Vulcanization: Continuous steam vulcanization at 152°C ensures full cross-linking, maximizing elasticity and fatigue life.
  • Pressure Testing: Each hose is 100% hydrostatically tested—ISO 1402 protocols followed. Random batch samples undergo impulse tests: 400,000 cycles at 133% WP.

10. Hydraulic Hose Wholesale: Professional FAQ
Q1: What is the typical material composition for EN856 4SP hoses?
EN856 4SP hoses are constructed with a high-grade oil-resistant nitrile rubber (NBR) inner tube, four spirally-wound high tensile steel wire layers, and a synthetic rubber outer cover. This composition ensures both flexibility and maximum burst resistance.
Q2: What diameter and pressure ranges are available in hydraulic hose wholesale?
We offer hoses from 3/8" to 2" ID with working pressures from 310 to 420 bar (4450 – 6090 psi), meeting ISO 3862/EN856 4SP standards. Higher burst rating available upon request for specific OEM projects.
Q3: Which international standards do your hoses comply with?
All hoses comply with ISO 3862, EN 856, SAE J517 (US), and are tested according to ISO 1402 (pressure), ISO 6945 (abrasion). Third-party certification is available for FDA/ROHS depending on the intended use (e.g., food grade, environmental).
Q4: What is the minimum bend radius, and why does it matter?
The EN856 4SP achieves a minimum bend radius of 210 mm, ensuring installation flexibility without kinks or collapse—critical for confined routing in construction and mobile hydraulic systems.
Q5: What is involved in hydraulic hoses made to order?
Made-to-order service includes custom branding, cover colors, special length/cutting, cover materials (flameproof, anti-static), and tailored packaging. All custom hoses pass the same rigorous batch and impulse lifecycle testing as stock items.
Q6: What are the installation recommendations for EN856 4SP hoses?
Install per ISO 17165-2: Use suitable connectors, avoid twisting, respect bend radius, and protect against abrasion at contact points. Always flush and pressure test the system post-installation.
