M22759/32-20-21 RED/BROWN BTF STRIPE

M22759/32-20-21 Red/Brown BTF Stripe – 20 AWG Silicone MIL-SPEC Wire for Fine-Gauge High-Temperature Wiring

The M22759/32-20-21 is a 20 AWG MIL-SPEC wire with a red base and brown BTF stripe, silicone insulation, and a silver-plated copper conductor. Manufactured to the M22759/32 military specification, it is designed for motorsport, aerospace, and high-performance vehicle wiring requiring fine-gauge performance and extended temperature capability. Supplied pre-spooled.

Red/Brown BTF Stripe Identification

The red base with brown BTF stripe (-21) pairs two warm earth-tone colours. Brown against red is a closer-toned pairing than the higher-contrast combinations later in the family, but the BTF stripe format provides reliable differentiation: brown is distinctly darker and less saturated than red, making the stripe visually separable from the base in direct inspection. The BTF stripe runs continuously for identification along the full wire length in a finished harness.

Fine-Gauge Red-Base Wire in Silicone Specification

All red-base variants at 20 AWG in the M22759/32 range share the same construction: stranded silver-plated copper conductor with silicone insulation rated at -65°C to +200°C continuous. At 20 AWG, these wires are suited to the lowest-current circuit positions in a motorsport or aerospace harness where the fine gauge and flexibility of the conductor, combined with silicone’s extended thermal performance, are required together.
