M22759/32 Tefzel Wire — 20 AWG, Blue/Yellow Stripe
The M22759/32-20-64 Blue/Yellow BTF Stripe — SKU: M22759/32-20-64-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 20 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, engineered for motorsport power and mixed-function wiring where enhanced mechanical insulation protection is required alongside the full chemical and thermal resistance of Tefzel.
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 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 power and actuator circuit wiring in race cars.
Blue/Yellow — Colour Code 64
Blue/yellow (code 64) at 20 AWG M22759/32 identifies CAN bus and data network power supply output conductors — the blue base marking the communication system family with the yellow stripe indicating an output or supply-to-component function, clearly identifying this as a power output conductor belonging to the data network system. PDMs and power distribution modules that distribute CAN bus supply power to multiple networked nodes route these bus power output feeds in blue/yellow at 20 AWG — the yellow stripe differentiating them from the active bus signal conductors (blue CANH) and the bus negative conductors (blue/black CANL) that share the same connector section, supporting accurate CAN bus wiring assembly without circuit confusion.
20 AWG — Gauge Selection
20 AWG M22759/32 sits between the lightweight signal gauges and the heavier power wiring tier — used for moderately loaded actuator feeds, switched control outputs, sensor supply circuits requiring more current than signal-gauge wiring can carry, and mixed-function conductors where the dual-wall Tefzel construction provides added insulation robustness for wiring routed through demanding environments in a race car chassis and engine bay. 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 mixed-function wiring must navigate in a professionally built race car harness.
