M22759/32-22-46 YELLOW/BLUE BTF STRIPE

M22759/32-22-46 Yellow/Blue BTF Stripe – 22 AWG Tefzel MIL-SPEC Wire for Motorsport and High-Performance Vehicle Wiring

The M22759/32-22-46 is a 22 AWG MIL-SPEC wire with a yellow base and blue 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/Blue BTF Stripe Identification

The yellow base with blue BTF stripe (-46) provides a strong warm/cool contrast combination within the yellow-base family of the M22759/32 22 AWG range. Blue against a yellow base creates a visually striking cross-spectrum pairing with excellent contrast, making this variant one of the most immediately distinguishable in the yellow family under any lighting condition. The continuous BTF stripe construction ensures identification is readable along the full length of the wire from termination to termination, regardless of routing or bundling.
