Knightsbridge JB0011 Weatherproof IP68 (@2bar) Plug and Socket Inline Cable Connector, 3-Pole, rated to 16 A,Black

They're easy to install and are made really well. They're small diameter and this means they can be rolled up easily when not in use

I needed this connector to do a cable splice of the power supply to a submerged rainwater harvesting pump. First impression is that it is well made and good quality, easy to assemble and would provide a high integrity connection. Only time will tell however whether this is effective and provides a truly IP68 watertight joint (meaning dust tight and good for being continuously immersed in water for a longer periods)!

Easy to assemble. The plug and socket arrangement is ideal as we swap lighting set ups around on our stand at craft fairs.I am considering using these for some pond equipment to make maintenance easier.

I had not seen this design before. Although rather fiddly to connect the cables, once done it is very easy to take part and reassemble the two ends. It seems to be waterproof - but not fully tested.A very useful and neat product.

I bought this to replace the inline 12V connector on my Noco Genius 10 battery charger which was suffering from a loose connection.Although my lead has just 2 wires, polarity is important for DC, so a normal mains 2 pin connector would be too risky. For this reason I went for a 3 pin connector with the earth pin unused in order to ensure correct polarity when connecting.Fitting was straightforward. If you have ever wired a mains plug you will be fine. Just remember to thread the wire through the seal before you wire it up!It works perfectly, and looks and feels very solid. It is also very compact (not much larger than the original and inferior Noco connector)I dont need it to be particularly weatherproof or waterproof as its only 12V. I suspect that the cable seals may not be watertight as my cables are flat twin cross section rather than round. This is not a fault of the connector as I am using it for an application its not really intended for.Highly recommended.

I have some Christmas lights that I need to extend the cable to. I have used a similar plug in the past and when they turned up today they looked like they'd do the job. There are 3 screw terminals per plug/socket piece and they come with 2x spare compression grommets for the seal.I've used the non-pluggable ones in the garden for a few years and never had a problem with water ingress. Note I only use them for low-voltage purposes <24V and don't have any safety mechanism for say tripping over the cable and exposing a live cable, unlike our fantastic ‘G Type’ (or BS 1363) UK plugs.

I have purchased several of these connectors in the past and they work fine. I have used them in light to moderate rain and also when there has been a heavy dew. I have had no issues regarding the resistance to water ingress. I do not use them as a permanent connection, rather to connect and disconnect. They can be a little tricky to disconnect if you over tighten. I find the answer is not to over-tighten the knurled ring. A firm tighten with fingers is all that is required.

very happy with this, quality good and straightforward to assemble...if you can wire a plug you can wire this
