M22759/32 White Tefzel Wire 28 AWG – MIL-Spec Motorsport Wiring Cable
The M22759/32 White Tefzel Wire 28 AWG — SKU: M22759/32-28-9 is a MIL-SPEC-qualified, ETFE (Tefzel) insulated hookup wire conforming to military specification MIL-W-22759/32. This is the professional standard wire used in motorsport wiring harness construction, aerospace electrical systems, and high-performance automotive builds requiring superior heat resistance, chemical resistance, and long-term reliability. Available from Arctic Performance Parts for professional harness builders across Norway, Sweden, and Denmark.
Why M22759/32 Tefzel Wire Is the Motorsport Standard
Tefzel (ETFE) insulation is chosen for professional motorsport wiring because it provides significantly superior performance compared to standard PVC automotive wire. The ETFE insulation is rated to 150°C continuous operating temperature, is highly resistant to fuel, oil, brake fluid, and coolant contamination, and maintains flexibility even at the extreme low temperatures experienced in Scandinavian winter conditions. The thin wall construction of M22759/32 wire also provides a higher conductor cross-section for a given outer diameter — reducing harness weight and bulk without compromising current-carrying capacity.
