High-pressure performance engineered for extreme environments
The global wire braid hydraulic hose industry is witnessing a transformative era driven by the massive expansion of construction, mining, and agricultural automation. As a critical component in fluid power systems, these hoses are the "veins" of modern machinery, transferring hydraulic energy with precision. Currently, the market is shifting toward higher pressure ratings and better flexibility, demanding materials that can withstand extreme temperatures and corrosive environments.
In the wake of global infrastructure development, the demand for SAE 100 R1, R2, and R5 series has reached an all-time high. Companies in North America, Europe, and Southeast Asia are increasingly looking for reliable Chinese manufacturers who can provide a balance between cost-efficiency and high-end technical certification like ISO9001 and IRIS.
The trend is moving towards "Smart Hydraulics," where hoses are integrated with sensors. Additionally, eco-friendly rubber compounds are being developed to meet stringent environmental regulations worldwide.
International buyers now prioritize "One-Stop Sourcing." They require not just the hose, but also the seals, fittings, and technical support to reduce downtime in critical projects.
Innovating Since 1996 - A Global Leader in Hydraulic Systems
Founded in 1996, Shaanxi Kelong New Materials Technology Co., Ltd. has evolved from a specialized research institute into a global powerhouse of hydraulic technology. We are not just a factory; we are a technological innovation hub integrating R&D, large-scale production, and international sales.
Our specialization covers high-pressure wire braid hoses, hydraulic seal sets, and coal mine auxiliary transportation equipment. Our products serve as the backbone for industries including Civil Aviation, High-speed railways, Engineering machinery, and Wind power. We pride ourselves on being in the Top 3 of the domestic coal machine sealing industry, aiming to reach the top 3 in the rubber hose sector globally within two years.

Advanced Technology Meets Uncompromising Quality
Nearly 180 engineers and 7%+ annual R&D investment ensure robust and diverse production capacity for global clients.
Our hydraulic hose production base adopts a complete set of automated production equipment imported directly from Italy.
Our sealing products utilize the state-of-the-art equipment and production technology of DMH Company in Austria.
Powering high-stakes projects across multiple continents
Extended range of wire reinforced and spiral hydraulic hoses
As the primary conduit for power in hydraulic systems, the wire braid hydraulic hose must balance several competing physical properties: strength, weight, flexibility, and longevity. At Kelong, we utilize a multi-layer construction philosophy. The inner tube is usually made of synthetic rubber resistant to the specific fluids it will carry, such as petroleum-based hydraulic oils. The reinforcement layers—where our expertise shines—consist of high-tensile steel wire braids. Depending on the pressure requirements (SAE 100 R1 vs. SAE 100 R2), these can be single or double layers.
Understanding the difference between SAE and EN standards is crucial for global procurement. SAE (Society of Automotive Engineers) and EN (European Norm) specify the minimum requirements for construction and performance. For example, the SAE 100 R12 is designed for high-pressure, heavy-duty applications with a four-spiral wire reinforcement, whereas the SAE 100 R2 is a standard two-wire braid hose widely used in general industrial applications. Our factory ensures that every meter of hose produced meets or exceeds these international benchmarks.
The global shift toward high-efficiency hydraulic systems means that hoses must now handle higher impulse cycles without failure. Our R&D team in Xianyang focuses on the "Impulse Life" of the hose. While a standard hose might last 200,000 cycles, Kelong’s premium wire braid hoses are tested to withstand over 500,000 cycles, significantly reducing the Total Cost of Ownership (TCO) for our clients in mining and construction.
Being based in Shaanxi, China, allows us to tap into an integrated supply chain while maintaining competitive pricing. However, "Cheap" at Kelong does not mean lower quality; it refers to our efficient production scales and automated Italian production lines that minimize waste. With over 180 technicians, we offer customized solutions, such as varying cover materials for abrasion resistance or ozone protection, which are essential for offshore rigs and high-altitude wind turbines.
In conclusion, whether you are looking for a discount SAE 100 R12 spiral hose or a specialized wire braid hydraulic rubber hose for textile or oil applications, Kelong New Materials provides the technological edge and manufacturing capacity to fulfill large-scale global demands. Our ISO9001 and IRIS certifications are a testament to our commitment to quality, and our $600 million asset base ensures that we are a partner you can rely on for the long term.
