In our This vs. That series, we're comparing (and contrasting) two seemingly similar products. A lot of products seem the same at first glance but can greatly affect the outcome of your next application. Today, we're taking a closer look at TXL and GXL Automotive Primary wires.

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

What is TXL Automotive Primary Wire?

TXL Automotive Primary 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 in both high heat and extreme cold. Due to its high durability, TXL Automotive Primary 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 Automotive Primary Wire?

GXL Automotive Primary wire is a thin wall, stranded, single-conductor automotive primary wire. The bare-copper wire conductor is wrapped with cross-linked polyethylene, 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.

How do they compare?

There is a lot of overlap between TXL and GXL  Automotive Primary wires. 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 Automotive Primary wire and GXL Automotive Primary wire are the applications, wall thickness, and weight. TXLAutomotive Primary wire's extra-thin wall makes it smaller more lightweight than GXL. GXL, however, is used primarily in engine compartments and where high heat resistance is required.
