| Subject: | milspec wire chart? |
I troll ebay periodically looking for deals on various 'stuff' to keep on
hand. One of the harder calls is milspec wire. I'm aware that the most
common designator for what we'd normally use is M22759. But I've discovered
that the number after the ' / ' can make a significant difference in what
we're actually getting. It seems that it can spec not only the insulation
type (PTFE, ETFE, and other stuff), but type of copper, plating on the
copper (tin, silver, nickel, etc), and apparently other stuff, as well. '
/16 ' seems to be tin plated copper with ETFE insulation. But there are
others that would be useful to us (or not), if we knew the entire list of
variants. For instance, I don't want any nickel plated stuff because I
sometimes solder, and apparently the nickel plated stuff is intended only
for crimping.
M22759/X-Y-Z
I know that Y is gauge. Z is color, but I don't have the reference list.
And X is the biggie variable, to know what we're getting.
Can anyone share a quick reference chart that breaks out each section of
the spec, and shows all the numbers/letters with their meanings?
Thanks,
Charlie

See below. There is a seller on ebay called ApexJr who sells
PTFE-coated wire in a large variety of colors. He advertises it as
M22759/11 but I asked him about it once and in fact it is probably
M16878/4 or similar (see chart). Anyway, it's practically the same as
M22759 PTFE aviation grade wire and it=99s handy to be able to buy
colors for different circuits. Seems identical to me except for the
colors.
