Features Type 4 Terminals — Standard. Integral parts of the element are of high strength to resist bending during tightening of the wiring con- nections. Type 4 is threaded extension of the cold pin. See terminal detail drawing in the Tubular Heater Overview section. Work Temperatures — See Tubular Heater Overview section. Bending — Customer’s minimum inside bending radius is 1-1/2". See bending require -ments in the Tubular Heater Overview section.

Applications Versatile tubular elements can be designed for use in most applications. See guidelines in the Tubular Heater Overview section. Advantages The metal sheath isolates and protects the re- sistor wire from the environment. At the same time, it maximizes heat transfer capability to the work. Tubular elements can be bent to put the heat where it works best.
