M22759/32-18-26 RED/BLUE BTF STRIPE

M22759/32-18-26 Red/Blue BTF Stripe – 18 AWG Silicone MIL-SPEC Wire Completing the Red-Base 18 AWG Range

The M22759/32-18-26 is an 18 AWG MIL-SPEC wire with a red base and blue BTF stripe, silicone insulation, and a silver-plated copper conductor. Built to the M22759/32 military specification, it is designed for motorsport, aerospace, and high-performance vehicle wiring requiring extended temperature capability and clear BTF stripe circuit identification. Supplied pre-spooled.

Red/Blue BTF Stripe: Completing the Red-Base Family

The red base with blue BTF stripe (-26) completes the four-variant red-base BTF stripe family at 18 AWG in the M22759/32 silicone range available in this batch — alongside red/black (-20), red/yellow (-24), and red/green (-25). Blue against red provides a strong cross-spectrum contrast, making this wire clearly distinguishable from the other red-base variants in a completed harness. With all four variants available, harness engineers can assign four unique identifiers within the red-base family at 18 AWG in silicone specification.

Cross-Spectrum Contrast in BTF Stripe Identification

The blue BTF stripe on a red base creates a colour combination where the warm red base and cool blue stripe sit at opposite ends of the visible colour spectrum. This cross-spectrum pairing typically provides strong identification contrast even under degraded viewing conditions such as engine bay lighting or in densely bundled harness sections.
