Our patented high-temperature design provides these advantages:

  • When energized, the patented split-sheath expands into contact with surrounding bore for maximum heat transfer and fast response.
  • When de-energized, the split-sheath contracts for easy, slide-out removal. Sunrods are guaranteed never to seize in the bore.
  • Uninterrupted hot zone and fully heated tip provides unmatched heat distribution without cold spots.
  • Slender continuous leads simplify wire management. High flexibility allows free motion when heating "floating" components.
  • The result is a micro cartridge heater offering longer life, uniform temperatures, and easy installation in the smallest devices.
