In the modern industrial era, the demand for Smooth Cover Hydraulic Hose has surged across the globe. Unlike traditional wrapped cover hoses, smooth cover variants offer superior aesthetics, easier cleaning, and significantly reduced friction when routed through tight machinery spaces. From the bustling construction sites of North America to the high-tech manufacturing hubs in Europe, these hoses have become the gold standard for high-pressure fluid conveyance.
The global market is currently witnessing a transition towards "smart" and "efficient" hydraulic systems. Engineers are prioritizing products that offer ozone resistance, abrasion resistance, and extreme flexibility. As a result, companies specializing in cheap but high-quality smooth cover hydraulic hoses are gaining massive traction in the international supply chain.
The integration of AI in manufacturing allows for laser-precision extrusion of smooth covers, ensuring uniform thickness and superior bonding between the rubber layers and the wire reinforcement.
There is a growing trend towards using halogen-free and recyclable rubber compounds. Companies are investing in R&D to create hoses that perform under pressure without harming the environment.
With the rise of heavy-duty mining and deep-sea exploration, the demand for hoses like the EN 856 4SH and SAE 100 R15 that can withstand over 6000 PSI is skyrocketing.
Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, which grew from Xianyang Kelong Rubber Products Institute.
It Is a Technological innovation company integrating R&D, production and sales, concentrates on hydraulic seal set, high-pressure hose, coal mine auxiliary transportation equipment, repairing coal mine auxiliary transportation equipment, technological service and ect. The products has been widely applied to Coal mining industry, Civil Aviation, High speed railway, Engineering machinery, Wind power and etc. The high-quality products and services are trusted by customers all over the world.

Our smooth cover hydraulic hoses are engineered for diverse environments. In the Middle East, our hoses are treated with special anti-UV compounds to withstand extreme heat and sand abrasion. In Northern Europe, the low-temperature flexibility of our SAE 100 R12 hoses ensures that forestry and mining equipment remains operational even at -40°C.
For industrial companies in Southeast Asia, where humidity is high, our hoses offer superior moisture resistance, preventing premature degradation of the steel wire reinforcement.
Why do global companies choose Kelong? As a direct Chinese Factory, we provide the perfect balance between "Cheap" price and "Premium" quality. By eliminating middleman markups and leveraging China's massive industrial supply chain, we offer wholesale prices that are 20-40% lower than European or American brands, without compromising on ISO9001 and IRIS certifications.
Nearly 180 engineers and 7%+ annual R&D investment ensure robust and diverse production capacity.
ISO and IRIS certifications. Strict checks throughout the production process guarantee top-notch quality.
Our hydraulic hose production base adopts a complete set of equipment imported from Italy for precision manufacturing.
Our sealing products utilize the advanced equipment and production technology of DMH Company in Austria.

At present, the company's total assets are 600 million RMB, with an annual output value of 300 million RMB. There are more than 400 employees in the company, including nearly 180 engineers and technicians, more than 40% of the total number of college graduate and Enterprise R & D personnel accounted for 17.5%. In the past three years, R&D investment accounted for more than 7% of the total income of the year. The company is the top three in the domestic coal machine sealing industry. and high-pressure rubber hoses and Frame-type handling vehicles are expected to enter the top three within two years. The main products share 8% in domestic market.
The transition from traditional wrapped covers to smooth cover hydraulic hoses is more than just a cosmetic upgrade; it is a fundamental shift in fluid power engineering. For decades, the industry relied on cloth-wrapped finishes which, while functional, presented several challenges in modern high-precision environments. Today, as global companies seek more efficient "cheap" solutions that do not sacrifice performance, the smooth cover technology has emerged as the clear winner.
One of the primary drivers of this trend is the rise of robotic assembly and automated warehouse systems. Smooth cover hoses, such as the SAE 100 R12 and EN 856 4SH produced by Kelong New Materials, are much easier to pull through cable carriers and machinery "snakes." The lack of surface texture means there is significantly less friction, which prevents wear on the hose itself and the surrounding components. This leads to a longer lifespan and reduced downtime—critical factors for any procurement manager looking to optimize their budget.
Furthermore, the cleaning requirements in industries like food processing (using specialized textile-braided hoses) and aerospace are strict. A smooth cover does not trap dirt, oil, or contaminants like a textured surface does. A simple wipe-down is often enough to maintain the exterior integrity of the system. This "clean technology" aspect is a major selling point in the European and North American markets where environmental and safety standards are exceptionally high.
As a leading China factory, Kelong New Materials has mastered the art of co-extrusion. This process ensures that the smooth outer cover is perfectly bonded to the reinforcement layer, eliminating the risk of cover separation even under extreme bending or vibration. Our investment in Italian production lines and Austrian sealing technology allows us to maintain tolerances that were previously only possible for high-end boutique manufacturers, but we offer them at a competitive price point that fits the "cheap" procurement strategy of growing enterprises.
Looking ahead, the industry is moving towards the integration of "smart hoses" equipped with sensors to monitor internal pressure and temperature in real-time. Kelong is at the forefront of this R&D, continually reinvesting over 7% of our revenue into innovation. We understand that whether you are in the coal mining pits of Australia or on a wind farm in the North Sea, the reliability of your hydraulic hose is the heartbeat of your operation. We invite global partners to visit our Shaanxi facility to witness the future of smooth cover hydraulic technology first-hand.
