M22759/16 Tefzel Wire — 16 AWG, Black/Blue Stripe
The M22759/16-16-06 Black/Blue BTF Stripe — SKU: M22759/16-16-06-PRSP is a genuine MIL-spec M22759/16 Tefzel-insulated stranded wire in 16 AWG with a black/blue 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/Blue — Colour Identification
Black/blue (code 06) at 16 AWG identifies dedicated data bus and communication circuit earth returns or shield drains that carry sufficient current to require 16 AWG gauge — the black base indicating the ground or return function with the blue stripe identifying it as associated with communication or data circuitry. The black base with blue stripe combination in colour code 06 provides a visually distinct wire identity that is immediately readable at connector entry points, splice locations, and terminal ends throughout the harness. In CAN bus and RS232 communication harness sections, maintaining a visually consistent colour convention between the signal conductors (blue base) and their associated return/shield conductors (black/blue stripe) creates an immediately readable harness structure that simplifies the verification of correct circuit routing and termination at every connector.
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/blue 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.
