The taps I use in my PC-70 are the simple Eheim taps, not their quick disconnects.
But I did use the quick disconnects for one of my fishtanks to be able to disconnect the canister filter easily for cleaning.
Be aware that they are 12mm OD - 10mm ID (for the 1/2" ones) and 10mm OD - 8mm ID (for the 3/8" ones).
