M22759/32 Tefzel Wire — 20 AWG, Green/Black Stripe
The M22759/32-20-50 Green/Black BTF Stripe — SKU: M22759/32-20-50-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 20 AWG with a green/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. M22759/32 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 service life in the more demanding routing environments associated with power and actuator circuit wiring in race cars.
Green/Black — Colour Code 50
Green/black (code 50) at 20 AWG M22759/32 identifies earth return and negative-function conductors within the green sensor supply and reference voltage circuit family — the black stripe marking the return or earth function of a conductor that belongs to the green reference supply group. Dedicated sensor reference voltage return conductors at 20 AWG in M22759/32 — where the combined return current of a reference voltage bus requires more than signal-gauge capacity — are identified with green/black. The black stripe consistently marks the return function while the green base cross-references the conductor to the specific reference supply circuit group it serves, supporting correct star-earth implementation for sensor reference wiring and enabling accurate return path continuity verification during harness commissioning.
20 AWG — Gauge Selection
20 AWG M22759/32 occupies the intermediate wiring tier between lightweight signal gauges and heavier power wiring — 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 routing 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 bends, grommet passes, and chassis runs that mixed-function wiring must navigate in a professionally built race car harness.
