color: red
Temperature range: long-term temperature resistance -70℃~270℃, short-term temperature resistance can reach 300℃.
Structural characteristics: double-layer silicone coated glass fiber cloth tube wall, spring steel wire reinforcement, high temperature resistant glass fiber thread wound on the outer wall; light weight, flexible bending, good high temperature resistance, smooth inner wall, low wind resistance, strong elasticity and flexibility, adopts Imported silica gel material, environmentally friendly and non-toxic, can be used for 5-10 years under normal working environment.
Application: suitable for hot air blowers, dehumidifier dryers, and plastic particles drying in the plastics industry; used for conveying hot and cold air in fans; used as any mechanical parts required for hot air and cold air transportation; widely used in transportation tools such as automobiles, airplanes, etc. Engines for trucks, vans, including 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, stay away from strong chemical corrosion, and the working temperature cannot exceed the temperature specified in the parameter.
