M27500-24TE1T14 Extruded ETFE Tefzel Wire | 24 AWG, 1 Conductor

The SAE AS22759 and M27500-24TE1T14 series Tefzel (ETFE) aircraft wire is a lightweight, high-temperature hookup wire designed for reliable performance in aerospace and military applications. Constructed with a stranded, tin-plated copper conductor and extruded ETFE insulation, it provides exceptional thermal and electrical stability for both airframe and avionics use.

This fluoropolymer-insulated single-conductor wire delivers outstanding resistance to moisture, chemicals, and abrasion, making it ideal for severe wind and moisture-prone (SWAMP) zones such as engine nacelles, as well as low-smoke, fire-resistant environments like aircraft cabins.

Key Features

• Rated for 600 volts and 150 °C continuous operation
