M22759/32 Tefzel Wire — 20 AWG, Green/White Stripe
The M22759/32-20-59 Green/White BTF Stripe — SKU: M22759/32-20-59-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 20 AWG with a green/white 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.
Green/White — Colour Code 59
Green/white (code 59) at 20 AWG M22759/32 provides the highest-contrast stripe combination within the green sensor supply and reference voltage circuit family at this gauge — the white stripe on green insulation delivering maximum legibility for conductors that must be positively identified among multiple green-family wires at a shared connector. Green/white is the priority identification stripe within the green circuit family at 20 AWG M22759/32 — reserved for the reference voltage or sensor supply conductor that must be found and verified most reliably during commissioning, fault-finding, or modification. In mixed-function harness sections where multiple green-family conductors serve different reference supply and sensor feed roles at the same connector, green/white’s exceptional contrast ensures it is instantly distinguishable from all other green-stripe variants under any access or lighting condition.
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.
