M22759/32-22-19 BROWN/WHITE BTF STRIPE

M22759/32-22-19 Brown/White BTF Stripe – 22 AWG Tefzel MIL-SPEC Wire for Motorsport and High-Performance Vehicle Wiring

The M22759/32-22-19 is a 22 AWG MIL-SPEC wire with a brown base and white BTF stripe, ETFE Tefzel insulation, and a tin-plated copper conductor. Manufactured to the M22759/32 military specification, it is designed for motorsport, aerospace, and high-performance vehicle wiring applications requiring reliable thermal performance and accurate colour-coded circuit identification. Supplied pre-spooled for professional workshop use.

22 AWG in the M22759/32 Tefzel Range

At 22 AWG, the M22759/32 series provides a very fine gauge suited to ultra-low-current signal circuits, ECU pin connections, and sensor wiring where minimum wire diameter and reduced harness weight are critical. The ETFE Tefzel insulation is rated at -55°C to +150°C continuous — the standard specification for all gauges in the M22759/32 Tefzel family — while the tin-plated copper conductor maintains consistent conductivity and resists oxidation across the full operating temperature range.

Brown/White BTF Stripe Identification

The brown base with white BTF stripe (-19) provides the highest-contrast identifier within the brown-base family of the M22759/32 22 AWG range, completing the main stripe colour sequence for the brown base group. White against brown delivers strong visual contrast that is readable under any lighting condition, making this variant among the most easily identified wires in the brown family. The harness engineer assigns the specific circuit function; the consistent BTF stripe format ensures that assignment is traceable throughout the harness layout. The continuous BTF stripe construction ensures identification is readable along the full length of the wire from termination to termination.
