M22759/32-18-64 BLUE/YELLOW BTF STRIPE

M22759/32 Tefzel Wire — 18 AWG, Blue/Yellow Stripe

The M22759/32-18-64 Blue/Yellow BTF Stripe — SKU: M22759/32-18-64-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 18 AWG with a blue/yellow striped insulation, supplied by Arctic Performance Parts as a pre-striped BTF (Build To Fill) shelf stock wire for professional motorsport wiring harness construction. M22759/32 is the heavier-wall variant of the Tefzel wire family, providing enhanced mechanical insulation protection for power and mixed-function wiring in demanding motorsport electrical environments.

M22759/32 — Dual-Wall Tefzel

Where M22759/16 uses a single thin-wall ETFE construction optimised for lightweight signal wiring, M22759/32 applies a heavier dual-wall Tefzel insulation that withstands greater mechanical stress — abrasion against chassis edges, cut-through under grommet compression, and sustained contact with adjacent components in a tightly routed power harness. Both variants share the same ETFE chemistry, retaining the 150°C continuous temperature rating, exceptional fuel and oil resistance, and chemical stability of the full Tefzel wire family. The thicker wall of M22759/32 extends the wire’s service life in the more demanding routing environments associated with 18 AWG power and actuator circuit wiring in race cars.

Blue/Yellow — Colour Code 64

Blue/yellow (code 64) at 18 AWG M22759/32 identifies CAN bus and data network power supply conductors — combining the blue base that marks the communication circuit family with the yellow stripe that indicates an output or supply-to-component function, clearly identifying this as a power conductor belonging to the data network system. PDMs and power distribution modules that distribute CAN bus supply power to multiple networked nodes route their bus power feeds in blue/yellow — maintaining the blue communication-family identity for these supply conductors while the yellow stripe differentiates them from the active data bus conductors (CANH, CANL) that also carry the blue base colour in the same connector section.

18 AWG — Gauge Selection

18 AWG M22759/32 covers the mid-range of the motorsport wiring spectrum — used for relay output feeds, switched actuator power, ignition coil primary circuits, sensor supply runs, and mixed-function control conductors where the dual-wall Tefzel construction provides added insulation robustness for wiring routed near heat sources, sharp chassis edges, or through abrasive grommet passages in a race car. The stranded tin-plated copper conductor provides the flexibility and vibration fatigue resistance essential for motorsport harness routing through the bends, grommet passes, and chassis runs that power wiring must navigate in a professionally built race car harness.

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 without the lead time of a custom stripe run. Professional harness builders working to tight build schedules can order the blue/yellow colour combination and receive it promptly — a key advantage when a specific colour is needed to complete a build on deadline. Arctic Performance Parts stocks a broad range of M22759/32 striped colours across standard motorsport power wiring gauges.
