M22759/16 Tefzel Wire — 18 AWG, Green/White Stripe
The M22759/16-18-59 Green/White BTF Stripe — SKU: M22759/16-18-59-PRSP is a genuine MIL-spec M22759/16 Tefzel-insulated stranded wire in 18 AWG with a green/white striped insulation, supplied by Arctic Performance Parts as a pre-striped BTF (Build To Fill) shelf stock wire for professional motorsport wiring harness construction. M22759/16 is the aerospace and motorsport industry standard wire specification for high-temperature, lightweight, and chemically resistant wiring in demanding electrical environments.
M22759/16 — MIL-Spec Tefzel Wire
M22759/16 wire uses ETFE (Ethylene Tetrafluoroethylene) insulation — marketed under the DuPont trade name Tefzel — which provides a unique combination of properties that standard automotive wire cannot match. Tefzel insulation is rated for continuous operation at temperatures up to 150°C, resists virtually all fuels, oils, hydraulic fluids, and cleaning solvents without degradation, and offers excellent abrasion resistance in a thin wall that minimises conductor diameter. These properties make M22759/16 the default wire specification for professional motorsport harness builders worldwide who require maximum reliability in the harshest electrical environments.
Green/White — Colour Identification
Green/white (code 59) is used in motorsport harness systems for sensor supply and reference circuits requiring maximum visual clarity at connector interfaces — the white stripe on green providing one of the highest-contrast combinations in the green base colour family. The green base with white stripe combination in colour code 59 provides a visually distinct wire identity that is immediately readable at connector entry points, splice locations, and terminal ends throughout the harness. In harness builds where multiple green-base wires terminate at the same multi-pin connector, the white stripe of code 59 stands out clearly from brown, red, orange, and gray stripe variants, making it a reliable choice for high-priority circuits that must be verified accurately during commissioning.
18 AWG — Wire Gauge
18 AWG is the standard signal and sensor wiring gauge for motorsport harness construction — covering ECU sensor inputs, analogue outputs, CAN bus, switched logic signals, and low-current actuator circuits. At 18 AWG, M22759/16 provides the correct balance of current capacity, flexibility, and harness weight for the majority of non-power circuits in a professional race car wiring system. The stranded conductor construction of M22759/16 provides flexibility and vibration fatigue resistance essential for motorsport harness applications where wires are routed around corners, through grommets, and along chassis runs that flex during normal vehicle operation.
BTF Shelf Stock — Ready to Ship
The PRSP (Pre-Striped, Pre-Stocked) designation indicates this wire is held as shelf stock at Arctic Performance Parts, available for immediate dispatch without the lead time associated with custom-striped wire orders. This is a significant advantage for motorsport harness builders working to tight build schedules — the green/white colour combination can be ordered and received without waiting for a custom stripe run. Arctic Performance Parts maintains a broad range of M22759/16 striped colours in 18 AWG and 16 AWG to support professional harness builds.
