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

What material is it made of? I assume it gets hot, and so teflon is
likely.

It sounds like "spaghetti" tubing intended for insulating bare wire
might work if nested.

The traditional manufacturer is Alpha. For example, Alpha TFT-250-18 is
made of teflon, has an ID of 0.042", walls 0.016" thick, so OD is
0.074", and costs $58.78 for 100 feet. FTF-250-13 is also teflon,
0.076" ID, walls 0.016" thick, so OD is 0.108", and costs $85.91. This
would be a lifetime supply.

Anyway, such tubing can be bought for the above dollars from the usual
electronic component distributors, like Newark and Allied.

One can also get clear PVC tubing, such as Alpha PVC-105-18 et al, for
about the same money, but in a wider variety of sizes.

Alpha may well make the very heavy walled tubing used in the tweeco; a
call to Alpha should tell the story.
