Tubing fitting question:

Ok so I'm back again with another silly question.

Could I fit 7/16 x 5/8 tubing on a 1/2 x 5/8 compression fitting with no worries?

The fittings I want to use are by Bitspower, and the tubing I wanna use is by Primochill. Primochill doesn't make a 1/2x5/8 tubing, but I'm worried the 3/4" OD Bitspower fittings will rub together when trying to install them on a XSPC Raystorm water block. I would prefer to use the 5/8" OD fittings, but that would mean using a different brand of tubing, unless the Primochill 7/16 x 5/8 tubing will fit with no leaks or other problems.

Any insight from you water cooling Jedi?

  1. If you were talking straights barbs you would be fine, but not sure with compressions.
    Because you are using a fitting that's ID is slightly larger than the tubing (will still work), the OD of the tubing will expand once its on the barb. Not by much, but might be enough to cause issues with getting the compression clamp on.
    To be honest, not sure.
  2. The compression ring will be your issue (if any), not the tubing size. I've heard stories about larger compression fittings not allowing side by side install on CPU blocks, but it really depends on the overall OD of the fitting ring and the placement of the I/O block ports.

    Yes you can, I have done just that with my Xspc 7/16 5/8 tubing on my own loop,

    7/16 is a smidge smaller than 1/2 but it just makes for a bit of wigglework when fitting, hot water will soften it up to help,
    @Rubix, remember my Gfx blocks?
    thats the closest mounts I've seen hehe

    Thats the fitting size mentioned on the tubing mentioned on an EK Gpu waterblock Kid Dark, you may find a similar fit,
    its very close but they don't actually interfere with each other and neither card has leaked in 6-8 months
  4. Yeah, I remember seeing's a very close fit, that's for sure.
  5. Yeah that pic is basically what I am pictuing with fittings for a 3/4 OD to look like. I'd prefer to avoid that and have some roon between if possible, I figure the same fittings with a 5/8 OD would give me a small (1/8" in theory) gap between them, which I think will both look better and more importantly be easier to get on & off.

    Thanks for the confirmation.
