China Flexible Rubber Air Hose - High-Quality Suppliers & Factory Direct Products
Rubber air hose,one of its usage is used as the connector between air compressor and other devices. It is widely used in underwater diving, diving dress and other types of surface supplied diving equipment. In the other hand, air hoses can also be used for air brakes between tractors and semi-trailers,used for conveying of air, inert gas and water in mining, construction, engineering, shipbuilding, steel production etc.
Rubber air hose is composed of three parts: tube, reinforcement and cover. The tube is made from high quality black and smooth synthetic rubber, mainly NBR, which is resistant to abrasion, corrosion and oils. The reinforcement is made from multiple layers of high strength synthetic fiber, making the hose have solid structure. The cover is made from high quality black and smooth synthetic rubber, is resistant to fire, abrasion, corrosion, oils, weather, ozone and aging.
