What is TXL Wire?

Our TXL wire is an extra-thin wall automotive primary wire. It is commonly used in applications where high heat resistance is a requirement. Common applications include the engine compartments of boats, tractors, buses, trucks, instrument panels, interiors, and a wide variety of other automotive applications. If your next application requires a wire with a small diameter and minimal weight, our TXL Automotive Wire is exactly what you need.


TXL wire features a stranded single bare copper conductor and chemically cross-linked polyethylene (XLPE) insulation. The stranded conductor provides extra flexibility. The XLPE insulation provides resistance to high temperatures, moisture, most solvents, and other environmental factors that are commonly found in automotive applications. We offer 22 AWG to 8 AWG TXL Wire with a variety of spool sizes.


TXL Wire has a recommended temperature range of -40C to +125C and a voltage rating of 50V. This automotive primary wire is recommended for use in applications where high-temperature resistance and small overall diameter are necessary. It also meets SAE J-1560, Chrysler (MS-8288), and Ford (M1L-123A) specifications.
