Description
Product Overview
GPT (General Purpose Thermoplastic) automotive wire is the most common standard cable used for automotive electrical systems. Manufactured strictly according to the SAE J1128 standard, our GPT wire features a highly conductive stranded bare copper core and a durable PVC jacket. It offers excellent flexibility and reliable performance, making it the ideal choice for automotive aftermarket, OEM applications, and general 12V/24V circuit wiring.
Typical Applications
- Automotive Wiring: General electrical circuits in cars, trucks, trailers, and RVs.
- Marine & Powersports: Interior wiring for boats, ATVs, and motorcycles.
- Custom Harnesses: Perfect for DIY automotive wire harnesses and aftermarket accessories installations (lights, radios, horns).
- Note: GPT wire is recommended for use in interior applications or areas protected from extreme environmental conditions.
