"The industry standard for extreme heat environments—engineered with high-performance PTFE and glass shielding for maximum reliability in temperatures up to 250°C."
The 6 AWG TGGT wire is a specialized high-temperature conductor designed for environments where standard silicone or XLPE insulation would melt or fail. It is the primary choice for internal wiring in commercial ovens, industrial heaters, and aerospace equipment. By combining PTFE (Teflon) tapes with a double layer of glass braiding, TGGT offers a unique combination of chemical resistance and extreme thermal stability.
250°C Thermal Performance: Engineered to operate continuously in environments reaching 482°F, making it the industry standard for commercial cooking and heating equipment.
Nickel-Coated Copper Conductor: Features 2% nickel plating per ASTM B355 to prevent oxidation and maintain electrical integrity at temperatures where standard tin-plated copper would degrade.
Triple-Layer Shielding: Features PTFE tape insulation covered by a glass yarn braid and an overall fiberglass jacket, offering a rugged defense against both extreme heat and mechanical wear.
Superior Chemical Resistance: The PTFE component provides an excellent barrier against oils, solvents, and industrial chemicals, preventing insulation breakdown in harsh manufacturing zones.
ENGINEERING OVERVIEW: 6 AWG TGGT 600V
APPLICATION: Commercial ovens, industrial heaters, kilns, and high-temperature appliance leads.
VOLTAGE: 600 Volts.
UL LISTING: UL 5256.
CONDUCTORS: Flexible (133 Strands) soft drawn 2% nickel-coated copper (per ASTM B355).
INSULATION: PTFE (Teflon) tape with a fiberglass moisture barrier.
JACKET: Braided fiberglass with a high-temperature finish.
TEMPERATURE: 250°C (482°F).
NOMINAL OD: 0.265 inches (6.73 mm)
Heavy-Duty Industrial Ovens: Main power wiring for large-scale heat-treating and curing ovens.
Smelting Plant Equipment: Power distribution for machinery operating in high-ambient heat zones.
Large Plastic Extruders: Connecting power to high-wattage barrel heaters on industrial plastic processing lines.
Commercial Boiler Leads: High-temperature power connections for large-scale steam and water boilers.
Industrial Kiln Feeders: Providing reliable power leads for ceramic and glass manufacturing.
Technical Note: All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyer’s responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes.

TGGT stands for Teflon, Glass, Glass, Teflon. It is a specialized high-temperature wire designed to handle continuous operating temperatures up to 250°C (482°F). The acronym describes its multi-layered construction: a flexible nickel-coated copper conductor wrapped in PTFE (Teflon) tape, bundled with fiberglass braids, and finished with a high-temperature Teflon jacket.
Yes, our TGGT wire is fully UL Style 5256 rated. UL 5256 is the official Underwriters Laboratories standard that certifies single-conductor appliance wiring material (AWM) for use up to 250°C and 600 volts. This rating guarantees that the wire has passed rigorous flame, thermal, and mechanical safety testing required for commercial and industrial heating applications.
TGGT wire is rated for continuous operation at temperatures up to 250°C (482°F). This high thermal ceiling is achieved through its specialized multi-layer construction, which includes PTFE (Teflon) tape insulation and fiberglass braiding. This makes it an ideal choice for high-heat environments like commercial ovens, industrial kilns, and heater bands where standard silicone-based wires would fail.
The primary difference is the temperature rating and insulation material. TGGT is rated for 250°C (482°F) and uses PTFE (Teflon) tape. MG (Mica Glass) wire is rated for 450°C (842°F). MG wire replaces the Teflon tape with Mica tapes, a mineral-based insulator that can withstand nearly double the heat of TGGT. While TGGT is the standard for commercial ovens and appliances, MG wire is required for "extreme zones" like industrial heaters, commercial kilns, and equipment operating near open flames or molten metal.
Yes. While TGGT has a slightly higher friction coefficient than THHN, it can be pulled through conduit. We recommend using a high-temp pulling lubricant and checking NEC tables for conduit fill, as the OD is slightly larger than standard 6 AWG wire.
TGGT is rated for 250°C and uses Teflon/Glass, whereas SRML is rated for 200°C and uses silicone rubber. TGGT offers better chemical resistance and higher heat limits, while SRML is generally more "rubbery."
Yes. Our TGGT features a fiberglass jacket impregnated with a high-temperature finish that resists moisture, oils, and chemical vapors commonly found in industrial plants.
Because TGGT is rated for 250°C, it has a much higher ampacity (current carrying capacity) than standard 90°C wire. However, always consult the NEC (National Electrical Code) for your specific equipment and ambient temperature to ensure the circuit is safely fused.
Yes. We carry a comprehensive range of high-temperature wire, including SIS, SRML, TGGT, & MG designed for everything from industrial motor leads to commercial oven circuitry. Each product page includes detailed engineering specs, such as strand counts, insulation materials, and UL listings.
