What is GPTM Wire?

GPTM stands for General Purpose Thermoplastic Marine wire. GPT is a common type of wire used in various electrical applications and GPTM is a specialized variant specifically for marine environments. The marine grade designation indicates that this wire is built to withstand the challenging conditions found on boats and other marine vessels, such as exposure to moisture, saltwater, oil, gasoline, and abrasion.

Benefits of Choosing GPTM Wire

GPTM wire offers a reliable, durable, and straightforward solution for various marine electrical systems, providing safe and efficient operation. It is made of tinned copper to prevent oxidation and coated with PVC for protection. The use of tinned copper ensures our GPTM wire is resistant to salt and moisture which are common challenges in marine settings. This GPT marine wire is rated for up to 60 volts and 80°C (176°F), suitable for wet conditions.

The GPTM wire in this category conforms to UL1426, SAE J1128, and USCG requirements.

UL1426 Sizes and Gauges Available

The overall diameter of the wire in this category ranges from 0.117" to 0.092" (14-18 AWG). We also offer spools and kits of GPTM-14, GPTM-16, and GPTM-18.
