I’m in the process of reinstalling my SaluSpa and I have a question about one of the connectors at the spa outlet (see photo).

I took it apart last year, so it’s possible I lost a piece along the way. The threading is exposed, and I’m not sure if everything needed is there to make a proper watertight connection.

I haven’t tested it with water yet to avoid losing water everywhere, so I don’t know if it would leak.

Also, it’s the same situation for the other small connector just below this one (not the big connector).

I’m mainly wondering:

if it’s supposed to connect like this

or if I’m missing a part (like a nut, gasket, or adapter)

If anyone recognizes this setup or has installed a SaluSpa before, I’d really appreciate your input.
