M22759/32-22-20 RED/BLACK BTF STRIPE

M22759/32-22-20 Red/Black BTF Stripe – 22 AWG Tefzel MIL-SPEC Wire for Motorsport and High-Performance Vehicle Wiring

The M22759/32-22-20 is a 22 AWG MIL-SPEC wire with a red base and black 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.

Red/Black BTF Stripe Identification

The red base with black BTF stripe (-20) opens the red-base family of the M22759/32 22 AWG range, introducing a distinct base colour that expands the total number of uniquely identifiable circuits in a professionally colour-coded harness. Red as a base colour carries strong power-positive associations across motorsport and automotive wiring conventions, and the black tracer provides clear contrast within the red family. 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.
