The new orifices from Aqualung for the new Calypso (128621) are terrible. Out of a batch of ten brand new orifices four would not close the valve to adjust it to 1inch/h2o. Under the microscope you can see that the plastic is lousy and the edge is not straight. It costs only 1,-US$ dealer price, but it's not even that worth.

I'll go back to the metal orifices of the elder Calypso (100128). I think they fit and even with 3,25US$ each you (or my customers) are better off.

So Herman, if you know someone who can get you the Aqualung 100128 orifice,you should be fine. Never had problems with those ones, they are actually easy to repair if they are damaged.

But it is correct, they don't fit in SP 2nds.
