Rated 5 out of 5 by from Another great Omega product! We have used this wire on multiple projects; does exactly what we need it to do and we will not buy any other brand.

Rated 5 out of 5 by from Great way to extend thermocouples. Very well made, solid thermocouple wire. I like that comments were added describing the electric properties of that particular wire.

Rated 5 out of 5 by from Good quality wire Needed to run some thermocouple extension wires, and this stuff did the trick! Would buy again.

Rated 5 out of 5 by from very durable I have used several thousand feet of this stuff in the last 15 years or so. it is great for rugged use in an industrial setting, especially if you are not using conduit or wire duct or anything. the only down side is the outer sheathing is "flat" and care must be taken to strip it back as to not damage the insulation on the conductors. The outer layer is thick, providing much more protection than the regular thermocouple lead wire. I am quite satisfied with this product.

Is there a 16 Pair, 24-gauge k-type Thermocouple cable? I'm looking to run it about 75' in conduit.

Asked by: JPayne
Thank you for your inquiry. Yes, the part number is Item# 16KX24SPP. FYI Cost of the wire is sold by the foot so quantity 1 = 1' wire and quantity 75 = 75' wire.

The insulation is Polyvinyl or Polyvinyl Chloride (PVC)?

Asked by: sean0817
Thank you for your inquiry. EXPP uses Polyvinyl Chloride (PVC) Insulation.
