EK-D5 Dual TOP O-Ring

I have bought a used EK-D5 Dual Top, the seller did not send the O-ring that is necessary to put between the block and D5 pumps.

Question can I put the original O-Ring that comes with the D5 pump between pump and the D5 Dual top?
One of my pumps is a Swiftech 655 original top and the other one is D5 with a EK-D5 X-Top Rev2.

I'm pretty sure that I can't install the EK Dual without the O-rings, anyone have any idea where to get them?
I propably should return the product to seller for a refund....

  1. You should be able to use the original ring yes, however as a rule whenever you disassemble something with an O-ring or gasket, you should replace it
    as long as your original is visually ok, I'd say use that
    replacements are cheap enough though for peace of mind

    Thank you, are you entirely sure I can use the original D5 O-Rings?
    It would be exact same dimension as the 2x O-Rings provided with the EK-D5 Dual?

    If I leaktest for 24h would you think my old O-Rings are safe to use, both of my pumps are 4years old.

    According manual for EK-D5 Dual Top I should use the ones provided with Dual top:
    "Do not forget to place o-rings
    that are enclosed in “EK-D5 Dual TOP” box"

    looking at the EKWB Manual
    3. ASSEMBLING THE “EK-D5 Dual TOP”
    WITH TWO PUMPS
    Take motor with impeller of your Laing D5 or
    MCP655 branded pump. Place it according to
    right picture. Do not forget to place o-rings
    that are enclosed in “EK-D5 Dual TOP” box
    .
    Use enclosed 2,5mm Allen key to screw the 16
    M4×16mm screws to secure the pumps.
  3. I have emailed EK and they reply it is not same O-Ring size..

    Also I check EK website the O-Ring is 61x3mm.

    Original O-Ring is 57x3.5mm :(
  4. Meh, that seems a little odd that they use a different size ring, logic says to me that it should be the same size,
    Either way EK should be able to supply a suitable sized replacement,
    failing that a local plumbers merchant may have the correct size for you
    /goes off to examine EK tops closer :)
