M22759/32 Tefzel Wire — 20 AWG, Blue/Green Stripe
The M22759/32-20-65 Blue/Green BTF Stripe — SKU: M22759/32-20-65-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 20 AWG with a blue/green 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/Green — Colour Code 65
Blue/green (code 65) at 20 AWG M22759/32 identifies reference voltage and regulated supply conductors within the blue communication circuit family — the green stripe cross-referencing the conductor to the reference or regulated supply function in harness systems where green consistently marks sensor reference and regulated voltage outputs. Communication modules and CAN transceivers requiring a dedicated regulated reference voltage — separate from the main bus power supply — are served by blue/green in M22759/32 at 20 AWG. The blue base identifies the conductor as belonging to the communication system while the green stripe marks its reference supply role, creating a colour cross-reference that allows technicians to trace the regulated reference supply throughout the communication sub-harness without documentation.
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.
