The product is equipped with a silicone sealing gasket, which is elastic, waterproof, firm, and stable 5. Suitable for electric water boilers, kitchen equipment, industrial cleaning equipment, commercial air conditioners, drinking water equipment, solar energy equipment, electric fryer equipment, etc. Specification: Item Type: Heating Tube Material: Stainless steel, brass, silicone Uses: Widely used in various heating applications Working Voltage: AC 220/380V Package List: 1 x Heating Tube 1 x Protection Cover Note: 1. The components should be stored in a dry environment. If the insulation resistance drops below 1 megohm due to long-term storage, they can be dried in an oven at about 200°C for several hours (or pass the components under low voltage for several hours) to restore the insulation resistance. 2. When carbon buildup is found on the surface of the tube, it must be removed before use to avoid reduced efficiency or potential damage to the components. 3. When melting bitumen, paraffin, and other solid oils, the voltage should be lowered initially and then increased to the rated voltage after melting to prevent power concentration and extend component life.
