I bought this because I have Paasche's other set of QD connectors but needed another one for my Sparmax single action SR. The threading fits perfectly with an Iwata to Paasche adapter but the male end of this does not fit into the female end of the of the quick disconnect. The diameter is just slightly too wide by a few tenths of a millimeter. This is a slightly different design with a different depth and washer setup compared to that set.So I broke out the files, sandpaper and polish. And after a little work it fits perfectly fine with no issues.So I would recommend this, but only if you are comfortable modifying it to work with the current models. Less waste is better after all.

It's genuine Passche part so it will fit work fine.
