spiral hydraulic hose reinforcement

Spiral hydraulic hose reinforcement is specifically designed for extremely high-pressure and high-impulse applications, providing superior strength and fatigue life compared to braided constructions.

  • Four-Layer Spiral (4SH or R12) | This common heavy-duty construction uses four layers of high-tensile steel wire wrapped in alternating directions, offering excellent working pressure stability and high impulse resistance for mobile equipment.

  • Six-Layer Spiral (R13 or R15) | The strongest available reinforcement, this hose utilizes six alternating layers of spiral-wrapped steel wire, making it ideal for the highest pressure demands, extreme pressure spikes, and massive equipment applications.

FAQs of Spiral Hydraulic Hose

What Is spiral hydraulic hose?

A spiral hydraulic hose is a reinforced flexible hose used to transport hydraulic fluids under high pressure in heavy-duty machinery and equipment.

Unlike braided hoses, it has multiple layers of spiral wire reinforcement that provide extra strength, stability, and resistance to pressure surges, making it ideal for construction, mining, agriculture, and industrial hydraulic systems.

  • Reinforcement structure – Built with four or six layers of spiral steel wire for maximum strength.

  • High pressure capacity – Designed to handle very high working pressures and extreme conditions.

  • Durability – Resistant to abrasion, weathering, and harsh environments.

  • Flexibility – Maintains good bend radius while ensuring strong performance.

  • Applications – Widely used in excavators, loaders, tractors, and heavy hydraulic machinery.

While spiral hoses are inherently more rigid due to their steel reinforcement, Kingdaflex utilizes a proprietary ‘Soft-Touch’ cover compound and optimized wire winding angle. This allows our R13 and R15 hoses to achieve a bend radius that is 15-20% tighter than the SAE standard, making installation easier in compact mining machinery without compromising burst strength.

Spiral and braided hydraulic hoses serve similar purposes but differ in construction, flexibility, and pressure capacity.

Spiral hydraulic hoses use multiple layers of steel wire for high-pressure performance, while braided hydraulic hoses have woven wire layers for better flexibility. Choosing the right type depends on your hydraulic system’s pressure and routing needs.

  • Construction – Spiral hoses feature four to six layers of spiral steel wire, providing maximum strength for heavy-duty applications. Braided hoses use one or two layers of woven wire, offering moderate strength but greater flexibility for easier installation in tight spaces.

  • Pressure capacity – Spiral hoses handle extremely high pressures, making them suitable for demanding machinery like excavators and mining equipment. Braided hoses support medium to high pressures, ideal for lighter machinery and less demanding hydraulic systems.

  • Flexibility – Braided hoses are more flexible and easier to route around bends, while spiral hoses are stiffer due to multiple spiral wire layers. This rigidity ensures high-pressure performance but limits tight installation angles.

  • Durability – Spiral hoses are highly durable under continuous high pressure and heavy loads, resisting kinks and bursts. Braided hoses are durable but less resistant to extreme pressure, making them more suitable for moderate applications.

  • Applications – Spiral hoses are preferred in construction, mining, and heavy industrial equipment, while braided hoses are used in agricultural, automotive, and general hydraulic systems where flexibility and moderate pressure handling are sufficient.

You should choose Kingdaflex spiral hydraulic hoses for their unmatched strength and durability in the most severe, high-pressure, and high-impulse environments like heavy construction, mining, and large industrial machinery. We utilize premium-grade materials and advanced manufacturing to ensure every hose delivers consistent performance and safety.

  • Extreme High-Pressure Tolerance (4-Layer) | Our 4-layer spiral hoses (SAE 100R12 / EN 856 4SH) feature four alternating layers of high-tensile steel wire, offering incredible burst strength and fatigue life for continuous operation under demanding, high-impulse pressure cycles.

  • Ultimate Pressure Rating (6-Layer) | For critical, highest-pressure systems, the 6-layer spiral construction (SAE 100R13/R15) provides maximum containment against system spikes and constant pressure, guaranteeing system integrity in the largest, most powerful hydraulic equipment.

  • Superior Durability and Service Life | Every Kingdaflex spiral hose is built with an oil-resistant synthetic rubber tube and a heavy-duty, abrasion- and weather-resistant outer cover, drastically extending the service life and reducing costly downtime and replacement frequency.

  • Global Quality Compliance | Our manufacturing adheres strictly to international standards like EN 856 and SAE J517, ensuring perfect compatibility with industry-standard couplings and components worldwide, providing peace of mind and reliable performance anywhere.

Standard braided hoses (1SN/2SN) are prone to expansion and failure under high-impulse conditions. You should upgrade to Kingdaflex Spiral Hoses when:

  1. System pressure exceeds 3,000 PSI (210 Bar) consistently.

  2. The equipment faces frequent pressure surges (water hammer effect).

  3. Safety factor requirements are critical (4:1 Burst/Working pressure ratio).
