Features:
Pneumatic brake hose is mainly used in the pneumatic brake system of various trucks, buses and heavy vehicles to transmit pneumatic power. The inner layer is made of special fluorine rubber, and the outer layer is made of 304 stainless steel wire multi-layer (single) layer. It has the characteristics of high temperature resistance, corrosion resistance, aging resistance, flame retardancy, earthquake resistance, small bending radius and long service life. Can also be widely used in aviation, chemical, machinery and other fields. Operating temperature
-45 ° C ~ +260 ° C, short-term up to 300 ° C, high temperature 200 ° C burst pressure > 3MPA, normal temperature burst pressure > 10MPA, after 200 ° C, 720 hours high temperature air aging to maintain 3MPA does not leak, pulse life more than 200,000 Times.
