Please verify that your machine’s dimensions match the product specifications before purchasing. Premium heating elements made of nickel-chromium alloy, offering high resistivity, low temperature coefficient of resistance, high-temperature capability, excellent corrosion resistance at elevated temperatures, rapid heating, durability, and resistance to breakage. Simple installation—requires only a standard screwdriver on most machines. Replace worn heating elements to maintain optimal sealing performance. Replace the kit when the PTFE cloth shows discoloration or when seal quality declines. Ensure compatibility by carefully checking the dimensions prior to purchase.
