I have just installed this in a bulkhead in a weatherproof outer case (4 pin). The bulkhead connector threads are too loose and when you try to tighten it in the bulkhead it slips. The rest of the connector looks fine. I usually buy plugs like this from the US, but decided to save a few bucks. I think you get what you pay for in this case.
