Please refer to the TFE-T series with insulated layers of fusion tape. 

** Two wires with insulated layers are joined together, but without a covering sheath.

† The weight of the wire on the spool is rounded up to the next highest weight (excluding packaging materials).

†† Overall color is transparent.††† To order special tolerance wires, add "-SLE" before the winding length in the model number. Ordering example: TT-T-24-SLE-1000, 1000' (300m) T-type duplex wire with insulated layers and special tolerance thermocouple wire.
