Duplex Straight Elements

 N/A Requires the use of 2 single elements.
Use thermocouple type code letter twice. Example: JJ14 or KK11. Dual elements with ceramic insulators are supplied as two single elements.
  • 1 The above insulated elements are supplied with refractory insulators: 1277 °C (2330 °F) maximum temperature.
  • 2 Actual cut length will be 1(1/2)" longer than specified length to allow for terminal connections
  • 3 Unless specified by option numbers above, all 8, 11, and 14 gauge elements will be provided with Opt. 2 (tig weld without twist). 20 gauge elements will be provided with Opt. 1 (twist and tig weld). All elements, regardless of gauge, over 96" will be supplied with Opt. 1 (twist and tig weld).
