What is the difference between GXL and TXL Wire?
While there are a lot of overlapping qualities between GXL and TXL wire, there are also some distinct differences. GXL and TXL wire both consist of multi-stranded bare copper core conductors, a temperature rating of -59°F (-51°C) to 257°F (125°C), cross-linked polyethylene (XLPE) along with meeting the SAE, Ford and Chrysler specification ratings. Both TXL & GKL wire are stranded, bare copper, special purpose automotive wire that is insulated with chemically cross-line polyethylene. The thin wall insulation has a smooth surface and is available in a variety of bright colors.
The two main distinct differences between the two wires are their differences in weight and wall thickness. GXL is the heavier option due to its thicker outer wall. TXL, on the other hand, is lighter due to its more lightweight and "extra-thin" outer wall.
