Description Milspec M22759/32 Tefzel (ETFE) insulated wire. Tefzel wire offers a small diameter conductor with enhanced mechanical toughness and resistant to harsh chemicals such as fuels, oils and other automotive fluids. Temperature Rating: -55 to 150 degrees C Tin plated copper conductor Extruded ETFE Sheathing These lightweight wires, developed for high temperature airframe and avionics, utilize an insulation of cross-linked, modified ethylene tetrafluoreothylene copolymer (ETFE). The result is a wire insulation system that offers a 150°C temperature rating, small size, light weight, with resistance to high PH cleaning fluids, fuels, lubricating oils, and many other chemicals. These wires are a mechanically tough, flame retardant, and weight saving solution. The ultimate in wiring for your project.
