The built-in thermocouple eliminates the need for an external temperature sensor. Also known as cartridge heating elements, these install into drilled and reamed holes in metal parts for quick heating through direct contact. All require a temperature switch or controller (sold separately) to regulate heat output. A braided stainless steel covering protects the wire leads from abrasion and damage. The sheath is Incoloy for excellent corrosion resistance.

To ensure a precise hole fit, use a reamer to enlarge the hole to an exact size and smooth the walls of the hole for the most metal-to-metal contact between the heating element and the part.

To connect the heating element to a temperature switch or controller, wire the yellow lead to the positive terminal and the red lead to the negative terminal. The two white leads connect to your power source.
