M22759/32-18-39 ORANGE/WHITE BTF STRIPE

M22759/32 Tefzel Wire — 18 AWG, Orange/White Stripe

The M22759/32-18-39 Orange/White BTF Stripe — SKU: M22759/32-18-39-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 18 AWG with a orange/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, 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.

Orange/White — Colour Code 39

Orange/white (code 39) at 18 AWG M22759/32 provides the highest-contrast stripe within the orange auxiliary circuit family — the white stripe on orange insulation delivering maximum legibility at 18 AWG conductor diameter for power conductors that must be positively identified during harness assembly, commissioning, and field service. In 18 AWG orange-family power harness sections where multiple conductors serve different auxiliary circuit functions at the same connector, orange/white is the natural priority identification choice — its exceptional contrast making it instantly distinguishable from orange/black, orange/red, orange/yellow, and other orange-stripe variants even under restricted access or poor lighting conditions during race car service.

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 orange/white 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.
