M22759/32-18-78 VIOLET/GRAY BTF STRIPE

M22759/32 Tefzel Wire — 18 AWG, Violet/Gray Stripe

The M22759/32-18-78 Violet/Gray BTF Stripe — SKU: M22759/32-18-78-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 18 AWG with a violet/gray 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.

Violet/Gray — Colour Code 78

Violet/gray (code 78) at 18 AWG M22759/32 identifies shield drain and screen conductors for shielded violet-family auxiliary function cables — the gray stripe marking the drain or screen function while the violet base cross-references the drain conductor to the violet-family circuit whose shielded cable it terminates. Shielded 18 AWG cables in violet-family auxiliary circuits — position sensor leads, solenoid control cables, and precision actuator feedback conductors where EMI suppression is required — need their drain wires identified with a colour that links the drain to the violet-family circuit it screens. Violet/gray ensures correct single-point grounding of these drain conductors and prevents them being confused with active signal conductors at the connector.

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 violet/gray 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.
