Designed for OEMs, repair shops, and industrial operators, this hose is built to withstand the rigors of high-pressure fuel, oil, and hydraulic systems, ensuring optimal equipment function and minimizing downtime.
1. Product Overview
This professional-grade high pressure automotive hose is a multi-layer reinforced synthetic rubber hose designed specifically for the transfer of fuels, oils, and hydraulic fluids in high-pressure environments. It serves as a critical component in modern automotive systems, heavy-duty machinery, and industrial equipment where failure is not an option. Constructed with a robust inner tube, multiple layers of high-tensile textile and/or steel wire reinforcement, and a durable, weather-resistant outer cover, this hose delivers consistent performance under pressure, temperature fluctuations, and exposure to harsh chemicals.
2. Key Features
- Extreme Pressure Resistance: Engineered with high-tensile steel wire braid or spiral reinforcement to handle sustained high-pressure operations without swelling or bursting.
- Superior Fluid Compatibility: Features a synthetic rubber inner tube resistant to degradation from modern fuels (including ethanol blends), oils, ATF, and hydraulic fluids.
- Excellent Flexibility & Kink Resistance: Maintains flexibility for easy routing in tight engine compartments and complex machinery, preventing flow restriction.
- Abrasion & Weather-Resistant Cover: The tough outer cover protects against physical abrasion, ozone, UV exposure, and general environmental wear, extending service life.
- SAE/DIN Compliance: Manufactured to meet or exceed relevant SAE, DIN, and other international standards for performance and safety.
- Precision-Crimped Fittings: Available with permanently attached, precision-crimped fittings (JIC, ORFS, Metric, etc.) for a leak-proof, reliable connection.

7. FAQ
Q: What is the main difference between a standard fuel hose and a high pressure automotive hose?
A: A standard fuel hose is designed for low-pressure return lines or suction applications. A true high pressure automotive hose is reinforced with steel wire to withstand the high pressures found in direct fuel injection systems, hydraulic systems, and power steering, offering significantly higher burst pressure and durability.
Q: Can this hose be used for both fuel and hydraulic oil?
A: Yes, our standard hose is constructed with a tube compound compatible with both petroleum-based fuels and mineral-based hydraulic oils. Always confirm fluid compatibility for specific, non-standard fluids.
Q: How do I select the correct hose size and fitting?
A: Selection depends on the system's required flow rate (determining inner diameter), maximum working and surge pressure (determining reinforcement), fluid type, and connection port type. Our technical datasheets and support team can guide you through this process.
Q: What is the typical shelf life and service life of the hose?
A: When stored properly in a cool, dark, dry place away from ozone sources, the shelf life is typically 4-5 years. Service life depends entirely on the application's operating conditions (pressure cycles, temperature, fluid, abrasion) but is designed for long-term performance in demanding environments.
Q: Do you offer custom hose assembly with fittings?
A: Absolutely. We specialize in providing custom-made high pressure automotive hose assemblies. Provide us with the hose type, length, and fitting specifications, and we will deliver a precision-crimped, leak-tested assembly ready for installation.
