The wire spiral high pressure hydraulic hose is a four-layer or six-layer spiral wire reinforced hydraulic hose designed for ultra-high pressure applications, strictly manufactured according to SAE 100R12 and SAE 100R13 standards. This high pressure hose features a oil-resistant synthetic rubber inner tube, multiple layers of alternating wire spiral hose reinforcement, and a weather-resistant synthetic rubber outer cover. As a professional manufacturer and supplier from China, we define this product as the industry's premier solution for extreme pressure impulse applications where standard wire braided hose constructions would fail.
Its core structure consists of four or six alternating spiral layers of high-tensile steel wire, separated by thin rubber layers to absorb dynamic stress. Unlike a wire braided hose, the spiral wire construction allows for better impulse fatigue life and higher pressure ratings while maintaining a larger bend radius. This is the definition of a true high pressure hose for heavy-duty hydraulics.
Key performance parameters include a maximum working pressure up to 6,000 PSI for R12 and 7,500 PSI for R13 (depending on dash size), a temperature range from -40°C to +121°C for petroleum-based fluids, and a strict 4:1 safety factor. The SAE 100R12 bend radius requirements are larger than R1 or R2 hoses, reflecting the heavier reinforcement, but the impulse life exceeds 500,000 cycles under extreme pressure peaks.
This wire spiral hose offers four core advantages: superior impulse fatigue life (over 1 million cycles in some constructions), exceptional burst pressure resistance (4x working pressure), high compatibility with heavy-duty crimped fittings, and reliable performance in the most demanding mobile and industrial hydraulic systems. It directly solves the pain points of frequent hose failure in high-pressure circuits, dangerous burst incidents, and costly downtime in mining, construction, and heavy manufacturing.
Primary applications include high pressure hydraulic hose systems on large excavators, mining haul trucks, hydraulic presses, injection molding machines, offshore drilling equipment, and steel mill hydraulic circuits. It is the go-to choice for any application requiring extreme pressure transmission with long service life.
The core problems it solves for buyers like engineering procurement managers and maintenance superintendents are: catastrophic hose bursts causing safety hazards, short service life in high-impulse circuits, and difficulty finding a supply partner who can provide certified, traceable wire spiral high pressure hydraulic hose with complete fittings and assembly service. We offer a full solution with comprehensive service and support, including pdf specification downloads, hose assembly with crimped fittings, and technical support for system design. Our quality commitment includes ISO 9001 certification, traceable batch numbers, and a standard warranty against defects.
Ultra-High Pressure Capacity: Working pressures up to 7,500 PSI (SAE 100R13), handling the most demanding hydraulic systems.
Superior Impulse Life: Designed for over 1 million impulse cycles at 133% working pressure, far exceeding SAE requirements.
Exceptional Burst Strength: Minimum 4:1 burst ratio provides critical safety margin in high-risk applications.
Heavy-Duty Crimped Fittings: Engineered for permanent, leak-free connections with our precision crimped fittings and adapters.
Excellent Flexibility for its Class: Despite the heavy reinforcement, the alternating spiral design maintains workable flexibility for routing.
Wide Fluid Compatibility: Compatible with petroleum-based hydraulic oils, synthetic hydraulic fluids, and water-glycol mixtures.
Applicable Users: Mining equipment operators, heavy construction contractors, steel mill maintenance teams, offshore drilling engineers, hydraulic press manufacturers, and heavy equipment fleet managers.

Inner Tube: High-grade, oil-resistant synthetic rubber (Nitrile/PVC blend). Provides excellent fluid compatibility and maintains flexibility at low temperatures.
Reinforcement Layers: Alternating spiral layers of high-tensile steel wire. Each layer is spiraled in the opposite direction of the previous layer, balancing radial and axial forces. This wire spiral hose construction provides superior resistance to impulse fatigue compared to any wire braided hose.
Intermediate Rubber Layers: Thin rubber layers between each spiral wire layer. These layers allow the wire layers to move independently during pressure surges, reducing internal friction and heat generation.
Outer Cover: Black, synthetic rubber (CSM or SBR based). Resistant to abrasion, ozone, UV, and weathering. Optional pin-pricked cover allows gas permeation to prevent cover blistering.
Cover Identification: Typically features a continuous colored stripe or branding imprint for easy identification.
