1. Product Overview
This industrial-grade flexible rubber hydraulic hose is a multi-spiral wire reinforced solution built to withstand extreme pressures and dynamic operating conditions. It serves as the vital conduit for transmitting hydraulic fluid, oil, fuel, and other compatible media within high-pressure systems. The core design philosophy balances immense tensile strength with necessary flexibility, allowing for easy routing around machinery components without compromising on pressure ratings or safety. It is the go-to component for OEMs, maintenance teams, and distributors who prioritize reliability and total cost of ownership over initial price.
2. Key Features
- Superior Reinforcement: Features multiple high-tensile steel wire spiral layers, providing exceptional burst pressure resistance and excellent impulse fatigue life.
- Optimal Flexibility: The specialized synthetic rubber construction ensures the hose remains highly flexible even in low temperatures, facilitating easier installation and reducing stress on fittings.
- Robust Tube & Cover: An oil-resistant synthetic rubber tube ensures compatibility with a wide range of hydraulic fluids. The abrasion- and weather-resistant cover protects against external damage from impact, sunlight (ozone), and harsh environments.
- Precision Engineering: Manufactured to exacting standards (SAE, EN, ISO), ensuring consistent inner diameter (ID) for efficient flow and reliable coupling attachment.
- Wide Temperature Range: Engineered to perform reliably in ambient temperatures from -40°C to +100°C (-40°F to +212°F), suitable for global operations.

7. FAQ
Q1: What is the main benefit of a spiral wire design over a braided wire design?
A: Spiral wire reinforcement is designed for very high working pressures and superior impulse fatigue resistance. It is typically used in higher-pressure applications (like SAE 100R12/13), while braided designs (SAE 100R1/2) are for medium pressure. Our flexible rubber hydraulic hose uses spiral wire for maximum durability in demanding cycles.
Q2: How do I select the correct hose size and specification for my application?
A: The key parameters are: System Working Pressure, Required Flow Rate (which determines Inner Diameter), Fluid Type, and Ambient Temperature/Routing. Our technical datasheets and support team are available to guide you through this selection to ensure optimal performance and safety.
Q3: Are these hoses suitable for use with bio-degradable hydraulic fluids (e.g., HETG, HEES)?
A: The standard NBR tube is compatible with most mineral and standard synthetic oils. For specific bio-degradable or phosphate ester fluids, please consult our technical team. We can often recommend or supply hoses with special tube compounds for full compatibility.
Q4: What is the typical minimum bend radius for this hose?
A: The minimum bend radius varies with the hose inner diameter. As a rule of thumb, it is typically 2 to 2.5 times the hose outer diameter. Exact figures for each size are provided in our detailed product catalog to ensure proper installation and longevity.
Q5: Do you supply pre-made hose assemblies, or just the hose?
A: We offer both solutions. We supply bulk hose for distributors and large OEMs with their own crimping facilities. Additionally, we can supply custom, ready-to-install hose assemblies crimped with high-quality fittings to your specified length and end connections, tested and certified for immediate use.
