High pressure air hose is mainly used as the connector between air compressor and other device. 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. It 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, mainly chloroprene rubber, which is resistant to fire, abrasion, corrosion, oils, weather, ozone and aging. The hose has a long service life as a result.
Applications: Used in high pressure and oil resistant working environment, it is suitable for mining, quarry, durable, long service life and high safety level
