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.
GXL wire is ideal for engine compartments and general wiring applications. GXL wire features a medium thickness insulation composed of chemically cross-linked polyethylene. This smooth surfaced insulation gives GXL wire additional protection and makes it highly resistant to moisture, solvents, and high temperatures. GXL wire withstands prolonged temperatures of up to 125°C (257°F) without melting or fusing.
Cross-Link GXL Wire: medium thickness wall.
Temperature Rating: -40°C to 125°C (-40°F to 257°F).
Voltage Rating: 60V DC.
Meets or exceeds SAE specification J1128, Ford ESB-M1L85-B, & Chrysler MS-8900.
Our Wire is top of the line and has excellent features. All of our automotive wire meets SAE J-1128, Ford and Chrysler specifications. Products in our inventory include SGX, GXL, TXL While some primary wire is rated for general use, such as circuit wiring, others are used in more specific scenarios, such as GXL which is mostly used in trucks and trailers. SGX wire is used in applications that have a need for high heat resistance and high-temperature performance. Wire is available in a range of sizes from 18 AWG to 2/0 AWG.
