SAE J1128 TXL Automotive Hook-up Wire

TXL automotive hook-up wire is designed for low voltage vehicle wiring applications where space savings, durability, and long-term reliability are critical. Manufactured to SAE J1128 standards, these single conductor wires feature a XLPE insulation that reduces overall wire diameter and weight compared to traditional automotive wire constructions while maintaining dependable electrical and mechanical performance. Available in wire gauges from 8 AWG to 24 AWG, the series includes both bare copper and tinned copper stranded conductors, along with 10 insulation color options to support organized routing and circuit identification.

With a 60 V rating and operating temperatures from -40 °C ~ 125 °C, TXL wire is well suited for automotive power distribution, lighting, sensors, control systems, and aftermarket electronics. The XLPE insulation provides resistance to heat, abrasion, ozone exposure, and common automotive fluids including engine oil, gasoline, diesel fuel, transmission fluid, coolant, and battery acid, helping maintain performance in demanding engine bay and chassis environments. Additionally, the wire is halogen free and RoHS compliant, making it a dependable solution for modern vehicle electrical systems.

FAQs

What makes TXL wire different from standard automotive primary wire?

TXL wire uses a XLPE insulation that reduces overall wire diameter and weight compared to traditional automotive wire constructions. This allows for more efficient routing in wiring harnesses while maintaining SAE J1128 performance requirements.

Does TXL wire resist automotive fluids and chemicals?

Yes. TXL wire is tested for compatibility with common automotive fluids including engine oil, gasoline, diesel fuel, transmission fluid, coolant, power steering fluid, and ethanol blends, helping ensure long-term reliability in vehicle electrical systems.

How does TXL wire differ from GXL or SXL wire types?

TXL has a thinner wall and lighter weight than GXL or SXL, making it easier to route in tight spaces while maintaining equivalent performance under SAE J1128 standards.
