Insulated T/C and Extension Wire Listings

Many of the insulated thermocouple and extension wire constructions listed below are available with Stainless Steel or Tinned Copper overbraid or Stainless Steel wrap as an option.

How To Order

Enter your order simply by stating the Part Number
and Length in feet required.

Note: The wire is separated into three different categories with different minimum length per order requirements.

Category A
Wire is available on 1,000 foot spools. It can be "re-spooled" on 100 foot spools for a nominal charge.
Category B
Wire is available on 500 and 1,000 foot spools.
Category C
Wire is available only on 1,000 foot spools.

Please note: Tempco reserves the right to alter the category designations as needed.
