SXL wire has a thick wall cross-linked insulation and is a durable special purpose automotive wire designed for use in engine compartments and other higher temperature applications. SXL wire withstands exposure to temperatures of up to 257°F (125°C). Compared to our standard automotive wire, the polyethylene insulation of our SXL wire has been heat treated creating a cross-linking structure in its molecules. This process produces an tougher insulation with excellent resistance to abrasion, higher temperatures, moisture, oil, grease, gasoline, and other damaging solvents. Crosslinked SXL wire is available in seven different solid colors (red, black, white, blue, green, yellow, and brown) and in wire gauge sizes from 18 gauge to 10 gauge. Made from stranded pure copper. RoHS compliant and meets SAE J1128, Ford ESB-M1L 123A, and Chrysler MS-5919. Voltage rating of up to 60 volts DC and 25 volts AC. Wire specifications are printed on the insulation. Manufactured in the U.S.A.
