Product Description

Product Description

The Watlow® FIREROD® not only set the industry standard for cartridge heaters, it continues to make improvements in construction and design. Among these innovations is the 1/8-inch FIREROD.

This miniature cartridge heater with swaged construction features high watt density, is capable of high operating temperature and provides long life in applications where it is essential to have a very small size. Like all of Watlow’s other FIRERODs, the 1/8-inch contains a resistance wire closer to the sheath and compacted MgO insulation, which maximizes heat transfer.
