TXL Wire vs GXL Wire | Product Knockout

Monday, February 24, 2020

TXL and GXL are both Automotive Primary Wire used and designed for a variety of different automotive environments. Both wires meet SAE J-1128, Ford and Chrysler standards. TXL and GXL also have a 125°C temperature rating.

What is TXL Wire? 

TXL wire is an extra-thin wall, stranded, single-conductor automotive primary wire with cross-linked polyethylene insulation. It is used primarily in automotive applications where small diameter and minimal weight are desirable. TXL automotive wire has a temperature rating of -51°C to +125°C, making it ideal for automotive applications that require reliability to both high heat and extreme cold. Due to its high durability, TXL wire is optimal for use in engine compartments. It is rated to SAE J-1128, Ford (M1L-123A) and Chrysler (MS-8288) specifications.

What is GXL Wire?

GXL wire is a thin wall, stranded, single-conductor automotive primary wire. The bare-copper wire conductor is wrapped with cross-linked polyethylene and allows for 50 volts, and operates best in a temperature range of -51°C to +125°C. It is used primarily in engine compartments where high heat resistance and operating at very low temperatures are required in accordance with SAE. It is rated to SAE J-1128, Ford (M1L-85B) and Chrysler (MS-8900) specifications.

TXL Wire vs GXL Wire

As you can see, there is a lot of overlap between TXL and GXL wire. Both of these Automotive Primary Wires have a bare copper conductor, XLPE insulation, the same temperature rating and are rated to SAE, Ford and Chrysler standards. The major differences between TXL wire and GXL wire are the application, wall thickness, and weight. TXL, as stated earlier, is used for applications where small diameter and minimal weight are desired. The extra-thin wall makes the wire more lightweight than GXL. GXL, however, is used primarily in engine compartments where high heat resistance is required. GXL is slightly heavier in weight compared to TXL due to a slightly thicker wall.
