The tweeco stuff is brown in color if that helps identify the material.

I am looking for very small plastic tubing with an ID of ~0.045" used in
my
tweeco gun for running aluminum. I don't have the OD with me but it is
around 0.125" .
My dealer charges me over 50 bucks for them. The brass end simply
unscrews
off of the tubing and I could use it on new tubing. I checked McMaster
but
they don't have it. It must be used for something else, mechanical oil
pressure switch line is close but the OD is too small. Thanks

The liner is usually PTFE, and is available from MSC. It's chemical
hosing.

Usually, I just lurk, soaking up all of the good info. This time, I
may be able to help.

The clue was the brown color. Perhaps what you have is PEEK
(polyetheretherketone) tubing. Tough, fairly hard and has a working
temperature range from -480 deg F to +480 deg F. Cool stuff, albeit,
pretty expensive and exotic. It could also be high temp polyimide,
which is also pricey, from a relative standpoint. Both types are
listed in McMaster-Carr, although not at the specific size that you
mentioned. A 0.125" OD x 0.062 ID PEEK tubing is listed for around $6
/ft and is indicated as a rigid tubing. The aforementioned Small Parts
has the same size listed as "semi-flexible" for around $20 for a 3
foot piece. A wider selection may be available from other vendors.

Hope that helps,
