SZJELEN SP21 Circular Cable Connector Plug Socket with Waterproof IP68 Rating - Panel Mount 21mm, Aviation Cable Connector (3Pin) Review

They are very poorly designed and manufactured. They don't screw together properly and I'm very dissatisfied with the quality.

Just the right thing for a secure and weatherproof camera connection at the rear of your motorhome. A cap on the truck connector keeps the contacts clean.

Do yourself a favor and spend your money on a quality product. This plastic junk needs to be soldered and if you solder it it will fall apart. I had to throw it in the trash. The money had to be spent on a real product.

These are quite small and fragile plugs. Probably suitable for indoor use, but does not trust the weather and the sun. Questionable amperage, I would not use more than 15A permanently. Solder cups accept stranded wire up to 14AWG.

Good for connecting monitor leads on a 2015 Chevy Spark flat tow truck to a bus. weather resistant. Be careful when soldering. If you don't have soldering experience, find someone who does. Any plastic connector will melt if you heat it too much. TIP = Tin the wire and leave with thick solder. Apply flux to the connector terminal and tin gently and quickly. Heat the wire before connecting the hot wire sensor connector. Cool with a damp cloth. Did. No melted plug.
