Specifications:Material:Stainless SteelColor: SilverRated Power: 300WOperating Voltage: 12VSuitable For: Mold temperature, heating furnace, drying furnace, solar water heaters, etc.Thread Diameter: 3.7cm / 1.46’’(appr.)Total length: 20 cm / 7.87’’(appr.)Tube Size: (L)×(W)17.3 × 2.6 cm / 6.81’’× 1.02’’(appr.) Features:Brand New and high quality.Simple structure, easy to install, and long lasting.Electrical heating element for home appliance, no spark, no naked fire and safe.Fast heat exchange rate, high mechanical strength and quick temperature raising rate.Widely used in a variety of saltpeter tank, sink, tank, acid tank, fusible metal melting furnace, air heating furnace, drying oven, hot stamping die and other devices. Tips:1.the components should be stored in dry place, if the insulation resistance dropped to less than 1 megohm due to long-term placement, it can be dried in an oven at about 200 ℃ for several hours (or put the element in low voltage for several hours), or restore insulation resistance.2.If you found that the surface of the tube has carbon, it must be removed before using,so as not to reduce efficiency, or even burn components.3.Melting asphalt, paraffin and other solid oils should reduce the voltage before using,and then rose to the rated voltage after melting, in order to prevent the concentration of power and improve component using life. Package included: 1 Pcs. Heater Element Fahrenheitto Celsius conversions: 35 F = 1.66 C, 120 F = 48.88 C, 140 F = 60 C, 170 F = 76.66 C We are commonly asked, "How many watts are required to heat one gallon of water up one degree?"      It requires 2.47 watts for one hour to heat one gallon of water one degree Celsius conversions:.
