Ok, understood but my comments regarding 'Festo' fittings are geared towards o-ring sealed union fitting, some most people in these forums tend to refer to them as Festos. I did not mean the fitting on the outlet of the UAT, even though it is a Festo product. If presented with a barbed fitting, particularly a captured barb like the UAT has, it is a far superior connection vs. that of an O-rind sealed and clamped around the outer surface of a hose. There is even a UAT alternative now that uses a press in union style connector to feed the pump, not a well thought out fitting choice in my opinion.

On the o-ring sealed unions, plenty will say they have worked fine. Extrapolating that statement into an expectation that they will always work fine is a dangerous assumption.

Ironically, the term Festo as a description of a particular fitting type is incorrect in itself, since Festo buys the clear majority of its fittings from another manufacturer.
