GPT Wire
General Purpose Thermoplastic (GPT) primary wire delivers reliable single-conductor electrical connectivity for automotive, truck, trailer, marine, and low-voltage point-to-point wiring applications. Manufactured with 100% pure copper conductors and smooth PVC insulation optimized for clean wire stripping, this SAE J1128-certified wire resists chemicals, abrasion, and heat up to 80°C (176°F), making it the industry-standard choice for OEM installations and replacement wiring in vehicles, boats, and equipment rated up to 60 volts.
- 100% pure copper conductors provide superior electrical conductivity and meet SAE J1128 specifications for automotive applications
- Available in gauges from 20GA to 8GA with extensive color selection including black, blue, brown, green, red, white, yellow, and specialty colors
- Smooth PVC jacket surface enables easy, clean wire stripping for faster installations and professional connections
- Chemical and abrasion-resistant insulation withstands exposure to automotive fluids, oils, and harsh environmental conditions
- Conveniently packaged in mini spools (10'-50'), 100' spools, and economical 1000' metal spools for projects of any size
