TFE Insulated

Series 508
Zesta Thermocouple Wire Series 508
Zesta Thermocouple Wire Series 508
The primary and duplex insulation of SERIES 508 is fused TFE tape which is spirally applied to the conductor and heated. This process, called sintering, forms the tape into a homogeneous layer. When sintered, the tape exhibits all of the advantages of extruded TFE insulation, while eliminating the concentricity problems associated with TFE extrusions.

The SERIES 508 is fully color coded and capable of continuous operation in excess of 500°F (260°C). Because the fusing process causes the duplex tape to fuse with the primary insulation, SERIES 508 is not recommended for applications where it is necessary to remove the outer tape while leaving the primary insulation intact.
