"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 16 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 Ceiling: 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. 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.

  • If you are looking for TGGT high-temp wire near you, Wire America stocks a full range of sizes from 18 AWG to 4/0 available by the foot to fit your exact project needs. We ship directly from regional hubs across the country, meaning most customers receive their order within 2 to 4 business days. We also offer expedited overnight shipping at checkout for emergency project deadlines.

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.

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.

TGGT is more flexible than standard building wire (like THHN) because it uses stranded copper and tape insulation rather than a solid plastic jacket. However, it is slightly stiffer than silicone-based SRML due to the multiple layers of glass and Teflon tape.

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.
