M22759/32 Tefzel Wire — 16 AWG, Red/Yellow Stripe
The M22759/32-16-24 Red/Yellow BTF Stripe — SKU: M22759/32-16-24-PRSP is a genuine MIL-spec M22759/32 dual-wall Tefzel-insulated stranded wire in 16 AWG with a red/yellow striped insulation, supplied by Arctic Performance Parts as a pre-striped BTF (Build To Fill) shelf stock wire for professional motorsport wiring harness construction. M22759/32 is the heavier-wall variant of the Tefzel wire family, engineered for motorsport power and mixed-function wiring where enhanced mechanical insulation protection is required.
M22759/32 — Dual-Wall Tefzel
Where M22759/16 uses a single thin-wall ETFE construction optimised for lightweight signal wiring, M22759/32 applies a heavier dual-wall Tefzel insulation that withstands greater mechanical stress — abrasion against chassis edges, cut-through under grommet compression, and sustained contact with adjacent components in a tightly routed power harness. Both variants share the same ETFE chemistry, retaining the 150°C continuous temperature rating, exceptional fuel and oil resistance, and chemical stability of the full Tefzel wire family, while the thicker wall of M22759/32 extends the wire’s service life in the more demanding routing environments associated with power circuit wiring in race cars.
Red/Yellow — Colour Code 24
Red/yellow (code 24) at 16 AWG M22759/32 identifies output and actuator feed conductors within the red positive supply family — the yellow stripe indicating a switched output or component supply function within a red-base power circuit group at the 16 AWG power level. High-current relay outputs and switched actuator feeds at 16 AWG often originate from the same power distribution node as the primary supply conductors — sharing a red-base colour convention. The yellow stripe on red/yellow distinguishes these switched output conductors from the unswitched primary supply conductors in the same connector, giving technicians instant clarity about which conductor is directly fused and which is relay-switched.
16 AWG — Gauge Selection
16 AWG M22759/32 handles higher continuous current than the 18 AWG gauge — suited to fuel pump primary feeds, main cooling fan circuits, high-current relay outputs, and dedicated sub-system power distribution where the conductor cross-section provides capacity for continuous loads in the 20–30A range. The dual-wall Tefzel insulation provides the additional mechanical protection required for heavier power conductors routed through the demanding environments of a motorsport chassis and engine bay. The stranded tin-plated copper conductor provides the flexibility and vibration fatigue resistance essential for motorsport harness routing through the bends, grommet passes, and chassis runs that power wiring must navigate in a professionally built race car harness.
BTF Shelf Stock — Ready to Ship
The PRSP designation confirms this wire is held as pre-striped shelf stock at Arctic Performance Parts, available for immediate dispatch without the lead time of a custom stripe run. Professional harness builders working to tight build schedules can order the red/yellow colour combination and receive it promptly — a key advantage when a specific colour is needed to complete a build on deadline. Arctic Performance Parts stocks a broad range of M22759/32 striped colours across standard motorsport power wiring gauges.
