The Wrapped Cover Air Hose is a general-purpose rubber air hose manufactured using a wrapped outer layer process, renowned for its economic practicality and balanced performance. The inner layer is made of black SBR synthetic rubber extruded into shape, offering excellent airtightness and moderate oil resistance, suitable for conveying air, water, and mild water-soluble chemicals. The reinforcing layer uses a high-tensile-strength synthetic fiber braided structure, providing stable pressure resistance and ensuring the hose does not bulge at a working pressure of 20 Bar. The outer layer, also made of black SBR rubber, forms a dense protective layer through a wrapping process, giving the hose excellent abrasion resistance, ozone resistance, and aging resistance, protecting it from outdoor sunlight and harsh environmental conditions. The hose operates in temperatures ranging from -20°C to +80°C, maintaining good flexibility in both extremely cold and hot conditions. The wrapped surface not only enhances the density and abrasion resistance of the outer layer but also gives the hose a neat appearance, making it an ideal choice for air and water conveyance in industrial, construction, and agricultural applications.
Construction Sites: Suitable for supplying air to tools such as concrete vibrators, pneumatic nail guns, and pneumatic picks on construction sites, as well as for temporary water supply and drainage operations. It can withstand the harsh operating environment of construction sites.
Mining Equipment Air Supply: Used for compressed air delivery to pneumatic control systems, pneumatic motors, and pneumatic grinders in factory workshops and mining operations, meeting daily production and maintenance needs.
Agricultural and Horticultural Irrigation: Suitable for farmland irrigation, orchard spraying, greenhouse water supply, and watering operations on golf courses and park lawns. Lightweight and flexible, it is easy to move and operate in the field.
Municipal and Public Utilities: Used for municipal road maintenance, landscaping irrigation, sanitation vehicle support, and various temporary water and air supply operations.
Mine Drainage and Slurry Transportation: Some large-diameter models can be used for mine pit drainage, tunnel water pumping, and the suction and compression of sewage and slurry containing silt.
Commercial and Mobile Services: Suitable for compressed air supply in auto repair shops, tire service stations, and mobile service vehicles, providing a reliable air source for equipment such as pneumatic wrenches and air pumps.
Balanced Pressure Resistance: The synthetic fiber braided reinforcement layer provides stable tensile strength, with a working pressure up to 20 Bar (300 psi) and a burst pressure more than three times the working pressure, ensuring safe and reliable daily operation.
Excellent Abrasion and Weather Resistance: The outer layer uses a coated SBR rubber, which is dense and uniform, possessing excellent abrasion resistance, ozone resistance, and UV resistance, allowing for long-term outdoor use without aging or cracking.
Excellent Flexibility and Knot Resistance: The hose is soft with a small bending radius, maintaining excellent flexibility even at temperatures as low as -30°C. It is less prone to kinking and tangling during use, improving operational continuity.
Lightweight and Portable Design: While maintaining strength, the hose is lightweight, making it easy to drag, coil, and store on-site, reducing operator workload.
Economical and Practical with High Cost-Effectiveness: SBR rubber material has a moderate cost and mature manufacturing process, making this hose cost-effective while meeting the needs of most general operating conditions.
Stable Adhesive Bonding: The inner layer, reinforcing layer, and outer layer are firmly bonded, exhibiting minimal deformation under pressure and preventing delamination, ensuring structural stability during long-term use.
Wide Media Adaptability: Suitable for air, water, and mild water-soluble chemicals, meeting the daily conveying needs of various industries such as industry, agriculture, and construction.
Flexible Customization Services: Supports mandrel manufacturing, providing finished components in different colors, lengths, and pre-installed with various connectors according to customer needs. OEM brand customization services meet individual requirements.

Q1: What media can this Wrapped Cover Air Hose handle?
This wrapped cover air hose is specifically designed for the conveyance of compressed air in heavy-duty industrial, mining, and construction applications. It is suitable for powering pneumatic tools, rock drills, jackhammers, and sandblasting equipment. It is not recommended for water, chemicals, or fuel transfer unless specifically approved.
Q2: What is the working temperature range of the hose?
The wrapped cover air hose operates effectively within a temperature range of approximately -20°C to +80°C for standard rubber compounds, making it suitable for use in diverse climates from cold winter conditions to hot industrial environments.
Q3: What makes the wrapped cover design different from smooth cover hoses?
