FAQs
Is M22759 wire flame retardant?
Yes. One of the primary reasons for the M22759 specification is safety. The fluoropolymer insulations (such as PTFE and ETFE) used in M22759 wire are inherently flame resistant and produce very little smoke. They are designed to self-extinguish and provide excellent fire-resistant performance in demanding aerospace and military applications. However, these materials do contain halogens, which can produce emissions during combustion, making them unsuitable for certain environments such as shipboard applications.
Can M22759 be used for automotive or marine use?
While it is an aerospace wire, it is extremely popular in professional motorsports (Mil-Spec wiring harnesses) because of its small diameter, light weight, and resistance to fuels and oils. In marine environments, the tin-plated versions are preferred to prevent corrosion.
When should I use Silver-plated vs. Nickel-plated conductors for M22759?
Silver-plated: Offers excellent conductivity and is easier to solder. However, it is susceptible to corrosion if moisture reaches the copper core.
Nickel-plated: Used for higher temperature environments (up to 260°C). It is much more resistant to corrosion but is harder to solder and requires specific fluxes.
How do I read the full M22759 part number?
A standard part number follows this format: M22759 / [Slash Number] - [Gauge] - [Color Code]. For example, M22759/32-22-9 breaks down as:
M22759/32: The specification (Cross-linked ETFE, Tin-plated copper).
22: The wire gauge (22 AWG).
9: The base color (9 is White).
Can I bury M22759 wire underground?
No. While M22759 is waterproof and chemically resistant, it is not "Direct Burial" rated. The insulation is relatively thin and "flows" under constant pressure (cold flow). Over time, a sharp rock or heavy soil pressure can squeeze the insulation until it thins out and shorts. If used outdoors, it should always be run through a protective conduit.
Does M22759 wire expire (Shelf Life)?
The M22759 specification does not define a specific shelf life for the wire. However, when stored under optimal conditions—typically 10°C to 30°C with moderate humidity—M22759 wire shelf life can be expected to exceed 20–25 years. Actual longevity may vary depending on storage environment, handling, and application requirements.

M22759 Wire Variants
M22759 wire is available in different sizes, weights, voltage ratings, conductors, insulations, and temperature ratings. M22759 wire is color-coded using numbers to designate the wire color and spiral stripe colors. The different components of the part number represent information about what’s inside the cable. Learning these crucial distinctions can help you determine which wire variant is needed for your application.
- The choice of insulation and conductor materials for M22759 wire directly affects its electrical characteristics. For instance, a silver-coated copper conductor wrapped in TFE insulation can be employed in high-temperature environments, handling voltages up to 1000 volts and temperatures as high as 260 degrees Celsius.
