Outside port noise query

[CMcB]

Hi guys, I have an outside port on my van(as pictured) originally it had one of those orange QRC hose fittings but they kept on leaking so i changed it to the metal one from gardiner as pictured. It rattles! Any ideas on a washer or fitting or something to stop it moving and where I would get it? It's a screw thread fitting.

If its one like this with 3/4" male thread on the end,

Then Grippatank sell a thin 3/4" BSP nut.

Depending on the remaining thread you might be able to use something like this

If its too thick then you might be able to file it thinner with a flat steel file.
