tiny plastic tubing source
 

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

Clippard makes a full line of tubing like that in various
materials.

You might check chemical or chromatographic supply houses. Fisher
Scientific, VWR, Supleco, Cole-Parmer or Alltech are good places to start.
You might also try calling McMaster-Carr and see if they can special it for
you.

FWIW, that tubing might be very cheap even from those sources. We needed
some 1/8 OD x 1/32 ID Teflon tubing at work a while back and a coil ran us
around $200, AIR.

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.

They carry lots of small tubing (and other useful things).

I don't have any on hand so I can't check the sizes, but take a look
at the plastic tubing used for vacuum lines on most auto engines...

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

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

--If you're going to run miles of wire thru this I suspect
you'll want a very special kind of tubing. One guy I know, who does
robotics with multiple cable runs, uses a teflon tube which seems to be
relatively immune to wear from braided steel cables. I think it comes
from MSC but not sure.

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,

Dang, that _is_ cold, it's good for 20.33 degrees _below_ absolute zero?
I wonder how they test that...

I would imagine shrinkage would be a real problem at that point.

Umm, considering my background in engineering, I really should have
caught that. BLUSH! I certainly deserved that raz.

Another ref lists the melting point as 633 deg F and max working temp
as 482 deg F. No lower limit listed.

I used to work with cryogens (liquid helium, at 4.7 Kelvin) so it
kind of caught my eye...

Maybe 4.2K?

How do you get stuff to work when it's so hot?

Well, it's left-handed Helium, of course.

Well, some magnets do work at the critical point, which I think
is 8 or 9 degrees. Maybe the ones you worked with ran well
above atmospheric pressure, to keep air out of the system.
That would raise it up above 4.2...

Kelvin scale - almost absolute zero where all stops (so we think).

Right. Kelvin. But 4 K is practically boiling hot.

Ah yes, we did run the magnets at a few inches of water of pressure.
The burst disk was at 5 inches, I seem to recall. Fun when one
of those goes...lovely cloud formations, lots of shouting on the
factory floor, and at least one person in talking to the boss about
cryogen costs and what they screwed up...

I may have to dig out my old paperwork & see if they say 4.7, or
if that was my imagination. Have you ever seen GE's Magnet Safety
tape? Lots of fun...

Try a small engine repair supply. I bought three different size very small

to had many sizes in stock.
