Where do I buy clamps? And how do I know tubing size?

Where do I buy clamps for swiftech 3/8 barb fitting? How do I know the size? Apparently its 1/2 even tough the barb is not 1/2.

Well, the truth is, I DO NOT HAVE THE LARGE FITTING/TUBBING, mine is the smaller one.

Im going crazy at frozen cpu, I cant find the pordutc Im looking for

More about where clamps tubing size
  1. Barb OD will match tubing ID. You want clamps for the OD of your tubing size. It depends on thickness of your tubing walls.

    Oh my, and how do I know that? What I can say is that when I bouth a MCRdrive from swiftech, it came with 2 diferent fittings and barbs, a very large one and a smaller one. The smaller one fit my tubing perfectly. Its the tubing included with the very first Zalman Reserator (blue pvc)

    If this gets too complicted, I might very well get 2 new compresion fittings
  3. Just make a measurement across the inside of the tubing- you'll want fittings/barbs that fit this. It's also pretty easy to find via the barb that fits- the opening of the barb is a tad smaller than the ID of the tubing. I don't know what size the Reserator tubing would be...I would guess 3/8"ID or 7/16"ID. I doubt it's 1/2"ID.

    Thanks for helping me with watercooling problems again, rubix. This is the fitting I need clamps for:

    I may also get a compression fitting (I actually think they are cool, so would be a welcome purchase)

    Is this the right one?

    I know for sure the fitting for the tubing is 3/8, so is the tubing OD 5/8?
  5. It depends if the OD of your tubing is 5/8".

    Are you doing barbs or fittings...or both? You'll need clamps that will secure 3/8"ID and whatever your OD size is, and for compression fittings, you would need to determine the same.
  6. To make things simple, you really have to know the ID (inside diameter) as well as the OD (outside diameter) of the tube. The OD even is less of a concern now as most tube now comes in same thickness. If you go with a 3/8 ID tubing then its OD is almost always 1/2.

    If you go with barb fittings then the OD is less important.

    I measured the tube. The ID is 8mm. The OD is 12mm. I can go either compression of barb, I dont care wich.

    I happen to already have a 3/8 barb, wich fits my tube perfectly, but I dont have the clamps. So I need either a Clamp for a 12mm OD tube or a compression fitting for a 8mm/12mm tube.

    But no store shows the measurement in mm, so Im screwed.
  8. Why did you measure your tubing ID in metric if you are trying to find the standard size?
  9. cause mm is the standard..
  10. It depends on what side of the pond you live on, and I only mentioned metric vs. standard as you seemed to be searching for a standard size. I know that Koolance and AquaComputer do offer some metric fitting sizes, so you might check into those.

    http://www.koolance.com/water-cooling/default.php?cPath=62_63_100 13mm- 1/2"
  11. well, the important is that the tubin walls are 2mm, and I know that a 3/8 (10mm) fits the tube perfectly (wich is ID 8mm, stretching it a little bit.)

    So adding the 2mm for the wall around the 3/8 10mm, that will give me a 14mm OD. If the compression is 1/2 (13mm) it will certainly put some pressure on the tubing, Its my believe it will secure it very well. The truth is that with the streching, the 2mm wall may reduce a little to 1,5mm, making the nozzle ID 3/8 OD 1/2 a perfect fitting. Ima gonna buy and see..
  12. Making simple things complicated I guess. :D

    Tubing size now becomes rocket science.
  13. I think this is becoming far more complicated than it should be. My experience from many forum threads is not to mix metric/standard watercooling components, including tubing and fittings.

    You'll often end up with those 'just don't quite fit' situations.
  14. whats the diference between nozzle and fitting? I noticed that when tis compression, its called compression nozzle, and when its clamp, its called barb fitting, but its the same piece.

    anyways, Im getting both a compression nozzle and a 3/8 clamp. One or the other has to work.
  15. Koolance calls all their fittings, 'nozzles'. A compression 'nozzle' is a compression fitting, a normal 'nozzle' is usually a barb.

    The images of either should make it very clear which is which. You only need clamps with barbs.
