"I bought this T-Splitter to connect up some LED garden lights. It is very well made and works well with rubber pond flex. Once connected and the glands screwed down tight I would be very surprised if any water managed to get inside. Overall a great solid product."
"I bought this joint to repair some dodgy driveway lighting which was constantly tripping the house circuit breaker due to water getting in to some badly designed junction boxes. It is well designed but not as easy to fit as the straight joint which I also bought. It is fine with smaller cables but it is difficult to accommodate the larger 13.5mm diameter cables it claims to handle. I'm sure the product will perform well at keeping out water as it seems to be well sealed but time will tell!"
"I used this connector to join 2.5mm² 3 core Arctic flex and I was not impressed. The 3-pole terminal block internals of this 3 way connector are the same as the in-line TeeTube (Scewfix Product Code: 92911) which works very well, however you are connecting half as much again copper conductor (and thus Live, Return and Earth copper sheathing) with the 3 way without any allowance for this in its design, because, as I say, it uses the same 3-pole terminal block internals as the in-line Teetube (2 way) connector, which I would recommend.
If I had used it to connect 0.75mm² or 1.5mm² 3 core maybe it would have perform better, but I was not, and in the specification it says it can except 4mm² . Personally, I doubt this claim very much.
My requirements of this installation did not allow for the use of a Wiska IP66 / IP67 Weatherproof Junction Box, which Screwfix use to do, or Screwfix's current offering, the BG Nexus 4-Pole Junction Box, (Product Code: 33518). If you need to connect round 2.5mm² 3 core flex or higher in a 3 way configuration I suggest you try and use one of the aforementioned products rather than the 3 way Teetube IP68 3-Pole T-Splitter."
