M22759/32-22-43 YELLOW/ORANGE BTF STRIPE

M22759/32-22-43 Yellow/Orange BTF Stripe – 22 AWG Tefzel MIL-SPEC Wire for Motorsport and High-Performance Vehicle Wiring

The M22759/32-22-43 is a 22 AWG MIL-SPEC wire with a yellow base and orange 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.

Yellow/Orange BTF Stripe Identification

The yellow base with orange BTF stripe (-43) provides a luminous warm-tone combination within the yellow-base family of the M22759/32 22 AWG range. Although both yellow and orange are warm high-visibility colours, the BTF stripe format ensures the orange tracer is cleanly and precisely defined against the yellow base, maintaining clear visual differentiation between this variant and adjacent yellow-family options. The harness engineer assigns the specific circuit function; the consistent BTF stripe format ensures that assignment is traceable throughout the harness. The continuous BTF stripe construction ensures identification is readable along the full length of the wire from termination to termination.
