Silicone Heater Hose consists of three layers with different material structure.

The inner tube is made of high quality silicone, therefore it bears both high and low temperature up to 220℃ for long term use.

The reinforcement is made from high strength Polyester braid, to withstand internal and external high pressure.

The silicone cover is to play the protective function, so the rubber hose could resistant to abrasion, corrosion, air oxidation, extreme weather, ozone, aging, sunlight and cutting, also with longer service life.

Mainly used in transport, coolant and engine heater system, radiator system, engineer construction, mining equipment, ships, injection molding machinery, agricultural machinery, oil pipeline, household appliances, various machine tools, etc.

Not just for liquid conveying materials, but for aviation, electronics, petroleum, chemical industry, machinery, electrical appliances, and other industrial sectors.
