M22759/16 Tefzel Wire — 16 AWG, Black/Red Stripe
The M22759/16-16-02 Black/Red BTF Stripe — SKU: M22759/16-16-02-PRSP is a genuine MIL-spec M22759/16 Tefzel-insulated stranded wire in 16 AWG with a black/red 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.
Black/Red — Colour Identification
Black/red (code 02) at 16 AWG is one of the most commonly specified striped black wires in motorsport harness building — used for dedicated negative return paths associated with primary power circuits where the red stripe identifies the return as belonging to the primary positive (red) circuit group. The black base with red stripe combination in colour code 02 provides a visually distinct wire identity that is immediately readable at connector entry points, splice locations, and terminal ends throughout the harness. In race car electrical systems that use dedicated star-earth returns for fuel pump, ignition, and ECU supply circuits rather than routing all returns to a common chassis earth point, black/red at 16 AWG identifies each dedicated power circuit return with a colour convention that cross-references directly to the red positive conductor it serves.
16 AWG — Wire Gauge
16 AWG is a heavier gauge than the standard 18 AWG signal wire, used for circuits carrying higher continuous current — relay outputs, fuel pump power feeds, ignition coil primary circuits, switched power distribution, and actuator drivers that exceed the current rating of 18 AWG in a motorsport harness. M22759/16 at 16 AWG provides the same Tefzel insulation performance as the lighter gauges with increased conductor cross-section for higher-current applications. 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 black/red 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.
