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 |

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. "habbi" wrote in message ...

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. |

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. -- "Steamboat Ed" Haas : For some reason hung up on Hacking the Trailing Edge! : Mexican Oompah bands... http://www.nmpproducts.com/intro.htm ---Decks a-wash in a sea of words--- |

LLoyd 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, David Glos |

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. You can see a photo and a little more infor at http://www.texloc.com/peek.html. David Glos |

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...

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... Dave |
