Tefzel wire is Race Spec's choice for wiring projects. Tefzel wire is used in many aerospace, motorsport, and industrial applications due to its chemical resistance and high heat capabilities. Tefzel wire is typically stranded tin-coated wire with either Crosslinked (M22759/32) or non-Crosslinked (M22759/16) insulation. Built for harsh environments, its super-tough ETFE insulation shrugs off extreme heat, chemicals, and radiation, making it ideal for aerospace, racing, and demanding industrial applications. Despite its thinness, it boasts superiority over other options with high voltage resistance and reliable performance.
