M22759/32-20-07 BLACK/VIOLET BTF STRIPE

M22759/32-20-07 Black/Violet BTF Stripe – 20 AWG Silicone MIL-SPEC Wire for Professional Fine-Gauge Harness Builds

The M22759/32-20-07 is a 20 AWG MIL-SPEC wire with a black base and violet BTF stripe, silicone insulation, and a silver-plated copper conductor. Built to the M22759/32 military specification, it provides reliable circuit identification and silicone-grade thermal performance for professional harness fabrication in motorsport, aerospace, and high-performance vehicle applications. Supplied pre-spooled.

Black/Violet BTF Stripe Identification

The black base with violet BTF stripe (-07) provides a spectrally distinct cool-tone identifier within the black-base family. Violet is clearly differentiated from blue (-06) and green (-05) in the cool-stripe range, and from yellow (-04) in the warm-stripe range, making each variant in the black-base family uniquely identifiable in a completed harness. The BTF stripe runs continuously for reliable identification throughout the harness routing.

Fine-Gauge Silicone Wire for Compact Harness Environments

At 20 AWG, M22759/32 wire is well suited to the dense connector environments common in modern motorsport ECU harnesses, where multiple circuits must terminate in a compact multi-pin connector body. The fine gauge reduces connector bulk and weight while the silicone insulation rated at -65°C to +200°C continuous provides the thermal performance required for circuits routed near heat sources in the engine bay.
