"The industry standard for extreme heat environments—engineered with high-performance PTFE and glass shielding for maximum reliability in temperatures up to 250°C."

Why Professionals Choose TGGT High-Temp Wire

The 14 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.

TGGT stands for Teflon-Glass-Glass-Teflon. The name describes its multi-layer construction: PTFE (Teflon) tape insulation, followed by a glass yarn braid, and a final fiberglass jacket impregnated with a high-temp Teflon finish.

The main difference is the temperature rating. SRML is typically rated for 150°C–200°C. TGGT is rated for 250°C. Additionally, TGGT uses Teflon tapes which offer better chemical resistance, while SRML uses silicone rubber which offers slightly more "rubbery" flexibility.

No. While TGGT is the standard for appliances up to 250°C, if your application exceeds this (such as inside a high-temp kiln or blast furnace), you would need to move up to MG (Mica-Glass) wire, which is rated for 450°C. Shop our entire High Temp Wire Collection here.

Yes. While fiberglass by itself can absorb moisture, the jacket on our TGGT wire is impregnated with a high-temperature finish that provides excellent resistance to moisture, oils, and flames.

Yes. 16 AWG TGGT is a standard replacement wire for internal oven circuitry in both commercial and residential settings. Because it is rated for 250°C (482°F), it can safely handle the high temperatures found behind the insulation and near the heating elements.

Because it uses 41 strands of nickel coated copper and thin tape-wrap insulation, 14 AWG TGGT is very flexible for its heat rating. It can be easily routed around heating elements and through tight internal appliance pathways without kinking. However, because of its multiple layers of glass and Teflon tape, it is slightly stiffer than silicone-based SRML (150°C/200°C).

UL 5256 is the safety standard for high-temperature equipment wire rated for 250°C. Having this listing ensures that the wire has been tested for safety and performance in the extreme conditions found in commercial and industrial heating appliances.

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.
