Rubber Air Hose
Rubber air hoses usually adopt SBR, NR or EPDM as tube material. The reinforcement layers are available in polyester fiber spiral line, high strength synthetic yarn and high strength synthetic cord. Finished products with bright appearance can remain flexible at temperatures ranging from -40 °C to +180 °C.
This type of high-pressure air hose is ideally for compressed air and inert gas delivering. Major application areas include mining, shipbuilding, civil engineering construction and casting.
