Steel wire ultra-high pressure resin hose (R7 series) is a cutting-edge fluid transfer solution designed to handle the most extreme pressure requirements in industrial applications. This high-pressure thermoplastic hydraulic hose combines the flexibility of resin materials with the strength of steel wire reinforcement, delivering exceptional performance in applications where traditional rubber hoses cannot withstand the pressure demands.
Our R7 ultra-high pressure resin hose features a precision-engineered construction consisting of a smooth inner tube made from oil-resistant synthetic rubber, multiple layers of high-tensile steel wire reinforcement (available in 2, 4, 6, and 8 layers), and a durable outer cover resistant to oil, weather, and abrasion. This innovative design allows the hose to operate at working pressures up to an impressive 400 MPa (58,000 psi), making it ideal for ultra-high pressure hydraulic systems.
Suitable for conveying a variety of hydraulic fluids including mineral oils, lubricants, glycol-based solutions, emulsions, and hydrocarbons, the steel wire reinforced ultra-high pressure hose operates reliably within a temperature range from -30°C to +80°C. It is important to note that this hose should not be used to transfer water, air, or phosphate ester-based fluids, as these can cause damage to the hose material and compromise safety.
The multi-layer steel wire reinforcement of our R7 series ultra-high pressure hose provides exceptional strength and pressure resistance, with working pressures ranging from 69 MPa to 400 MPa and burst pressures reaching up to 1000 MPa (145,000 psi). This makes it the perfect solution for applications requiring extreme pressure performance.
Compared to traditional rubber hoses with similar pressure ratings, our ultra-high pressure resin hose is significantly lighter and more flexible. This makes installation and handling much easier, reduces fatigue on equipment components, and allows for tighter bending radii in confined spaces.
The synthetic rubber inner tube offers excellent resistance to a wide range of hydraulic fluids, ensuring long-term performance and preventing fluid degradation. The resin outer cover provides additional protection against chemicals, oils, and environmental factors, extending the service life of the hose.
The steel wire ultra-high pressure resin hose has a smaller outer diameter compared to rubber hoses with equivalent pressure ratings, making it ideal for use in applications where space is limited. This compact design also reduces the overall weight of the hydraulic system, improving equipment efficiency.

Steel wire ultra-high pressure resin hose is essential for industries that require ultra-high pressure fluid transfer capabilities. It is commonly used in:
Water jet cutting machines and high-pressure cleaning equipment
Hydraulic testing systems and pressure testing equipment
Oil and gas exploration and production equipment
Aerospace and aviation hydraulic systems
Automotive manufacturing and testing facilities
Heavy machinery and industrial equipment
Mining and construction equipment requiring high-pressure hydraulic power
The maximum working pressure of our R7 series ultra-high pressure resin hose is 400 MPa (58,000 psi) for the 8-layer reinforced version. Different reinforcement layer options provide varying pressure ratings to suit different application requirements.
No, steel wire ultra-high pressure resin hose is not recommended for transferring water or air. It is designed specifically for use with hydraulic fluids such as mineral oils, lubricants, glycol-based solutions, emulsions, and hydrocarbons. Using it with water or air can cause premature failure and safety hazards.
R7 series ultra-high pressure resin hose offers significantly higher pressure ratings, is lighter in weight, more flexible, and has a smaller outer diameter compared to traditional rubber hoses with similar pressure capabilities. This makes it easier to install and more suitable for space-constrained applications.
The steel wire ultra-high pressure resin hose operates reliably within a temperature range from -30°C to +80°C. Operating outside this temperature range can cause damage to the hose material and reduce its service life.
