Colour: Black
Temperature range: long-term temperature resistance -70℃~+130℃, short-time temperature resistance can reach +150℃.
Structural features: double-layer neoprene coated glass fiber cloth tube wall, spring steel wire between the two layers of coated cloth, the outer wall is wound with high temperature resistant glass fiber wire; light weight, flexible bending, good high temperature resistance and air tightness, inner wall Smooth, low wind resistance, can be used for 5~10 years under normal working environment.
Application: Used for mechanical parts such as dehumidifiers and dryers in the plastic machinery industry, fans and smoke exhaust systems to suck cold and hot air; can be used as any mechanical parts required for hot air and cold air transportation, and are widely used in transportation tools such as cars, airplanes, trucks, etc. Trucks, including engines for military tanks and other equipment.
Installation requirements: avoid surface friction. Keep a proper distance from the wall, the ground, etc., cannot exceed the bending radius specified in the parameter table, and stay away from strong chemical corrosiveness. The working temperature cannot be used in an environment exceeding the temperature specified in the parameter.
