M22759/32-22-16 BROWN/BLUE BTF STRIPE

M22759/32-22-16 BROWN/BLUE BTF STRIPE — 22AWG (0.35 mm²) Mil-Spec Motorsport Tefzel Wire

The M22759/32-22-16 BROWN/BLUE BTF STRIPE is a 22AWG (0.35 mm²) striped Tefzel (ETFE) motorsport wire supplied by Arctic Performance Parts as part of the M22759/32 mil-spec wire range. The brown/blue stripe colour combination makes this wire immediately identifiable within a completed harness, supporting accurate tracing, fault-finding, and documentation of complex motorsport wiring looms. This wire is manufactured to MIL-W-22759/32 specification, the standard used by professional motorsport harness builders worldwide for its combination of light weight, chemical resistance, and high-temperature performance.

M22759/32 Tefzel Wire — Technical Overview

M22759/32 wire uses an ETFE (ethylene tetrafluoroethylene) insulation jacket — commonly known by the DuPont trade name Tefzel. This insulation material provides a rated operating temperature of 150°C continuous, significantly higher than standard PVC or cross-linked polyethylene cables. ETFE insulation is resistant to aviation fuel, brake fluid, engine oil, hydraulic fluid, and cleaning solvents — all fluids commonly encountered in a motorsport environment. The thin wall insulation keeps overall wire diameter minimal, reducing harness weight and diameter without compromising protection. 22AWG Tefzel wire handles higher current loads than 24AWG while remaining light and flexible — ideal for power feeds, relay outputs, and circuits where a slightly larger conductor cross-section is required without moving to heavier TXL wire.

Brown/Blue Stripe Colour Coding

The brown/blue BTF (behind the firewall / base with tracer) stripe on this wire supports clear circuit identification throughout the harness. In professional motorsport harness practice, each circuit type is assigned a specific base/stripe colour combination in the wiring schematic, allowing technicians to trace any wire from ECU pin to sensor connector without confusion. This specific colour variant is commonly used for PDM supply wire identification within a professionally laid-out motorsport harness, making it a practical choice for PDM and fuse box supply circuits.

Typical Motorsport Applications

This 22AWG (0.35 mm²) brown/blue Tefzel wire is well suited to power feed circuits, relay outputs, fuel pump signals, injector drive wiring, and medium-current motorsport circuit runs. Specifically, it is frequently used for fused distribution and PDM input wiring and power distribution module feed circuit runs in race cars, rally vehicles, hill-climb builds, and trackday-prepared road cars. For rotary engine applications, Tefzel wire of this specification is the correct choice for any wiring that runs near the exhaust manifold, rotor housings, or other high-temperature surfaces where PVC insulation would degrade rapidly.

Supplied on the Shelf — BTF Stripe Wire

This wire is listed as an “On The Shelf” BTF stripe variant, meaning it is available for order without minimum reel quantity requirements that apply to full custom-stripe orders. Pre-striped wire from stock allows harness builders to specify multiple colour variants from a single order, reducing lead time and simplifying procurement for professional and enthusiast builds alike.

Available at Arctic Performance Parts

Arctic Performance Parts supplies M22759/32 Tefzel wire in a wide range of AWG sizes and colour combinations to support professional harness builders, motorsport workshops, and performance enthusiasts across Scandinavia. Stock is maintained for popular colour variants with additional quantities available on a 1–2 week lead time from our specialist wiring suppliers.
