M22759/16-20-60 BLUE/BLACK BTF STRIPE

M22759/16 Tefzel Wire — 20 AWG, Blue/Black Stripe

The M22759/16-20-60 Blue/Black BTF Stripe — SKU: M22759/16-20-60-PRSP is a genuine MIL-spec M22759/16 Tefzel-insulated stranded wire in 20 AWG with a blue/black 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

M22759/16 uses ETFE (Ethylene Tetrafluoroethylene) insulation — the DuPont Tefzel formulation — providing continuous operation at up to 150°C, exceptional resistance to fuels, oils, hydraulic fluids, and solvents, and outstanding abrasion resistance in a thin-wall construction that minimises conductor diameter and harness weight. These properties make M22759/16 the default wire for professional motorsport harness builders who require maximum reliability in race engine bays, cockpit wiring, and chassis loom applications.

Blue/Black — Colour Code 60

Blue/black (code 60) at 20 AWG is used for CAN bus negative conductors, communication circuit return paths, and data bus earth references within the blue communication wire family — the black stripe indicating the negative or return-path function of the blue circuit pair. In CAN bus wiring, the two bus conductors are conventionally CANH (high) and CANL (low). Using blue/black for the CANL conductor creates a clear and consistent pairing with the plain blue CANH wire — a colour convention that allows any technician to identify the correct CAN bus polarity at every connector without consulting the harness documentation.

20 AWG — Gauge Selection

20 AWG sits between the lightweight 22 AWG signal wire and the standard 18 AWG harness gauge — used for sensor circuits requiring slightly more current capacity than 22 AWG can provide, switch inputs with higher loop impedance requirements, and ECU output circuits where the load current dictates a step up from 22 AWG without requiring the full capacity of 18 AWG. It is a versatile intermediate gauge widely used in professional motorsport harnesses. The stranded tin-plated copper conductor provides the flexibility and vibration fatigue resistance essential for motorsport harness routing around corners, through grommets, and along chassis runs subject to flex during vehicle operation.

BTF Shelf Stock — Ready to Ship

The PRSP designation confirms this wire is held as pre-striped shelf stock at Arctic Performance Parts, available for immediate dispatch. Professional harness builders working to tight build deadlines can order the blue/black colour combination without waiting for a custom stripe run — a key advantage when a specific colour is needed to complete a build on schedule. Arctic Performance Parts maintains a wide range of M22759/16 striped colours across multiple AWG gauges to support professional harness construction.
