Holding tank pump out deck fittings USA

[Fascadale]

We are fitting a holding tank to use both in Europe and the US

I’m thinking of using one of these deck fittings Chromed Bronze Deck Plate Waste Out 38mm/51mm

Are European and US fittings compatible?

Thanks

From experience in the USA you could use it as a lot of places seem to have the graduate cone adapters but some places use the cam lock type - think mostly 3" diameter.

Polypropylene 2" Female Camlock Fitting x 2" Male Plastic Pipe Thread

Polypropylene 1 1/2" Male Camlock Fitting x 1 1/2" Male Plastic Pipe Thread

Been too long to remember the UK option.
