3 Pole Wire Connector Waterproof IP68 External Electrical Junction Box,M20 2way 3pin for Cable Ø0.18-0.4in for Outdoor Underground Cable, LED Street Landscape Lights,CE Certified 2Pack

They work very well

seals great, I used it to fix a outside cord works good and keeps the water out

cheaply made, good thing It came with two in a package. plastic is brittle around the sealing nut, but It did work for my application for my water fountain in my pond. Connector is underwater does not trip the gfci anymore

Our old fountain pump burned out. Unfortunately the fountain installer didn't use a conduit for the pump wire. We had to cut the plug off leaving about a foot of wire then reattach the wires using the connectors bought from Amazon. Worked perfectly and very easy to install with no prior electrical knowledge. Our fountain pump had 3 different colored wires. Green (ground) White (neutral) and Black for (live). Just needed to make sure you inserted wires correctly into connector.

Delivered on time. Matched pictures and specks. WORKED PERFECT.

These are labeled as M20 and claimed to fit cables that are 0.4 inches in diameter (title) or 10 mm in the specifications. I tried to use them with a 3 wire cable that is just under 10 mm OD but the supplied rubber rings are around 7 mm inside diameter. The product description clearly indicated "with two sizes of rubber ring" but there was only the small ring included. I really needed the product now, so I cut extra insulation jacket off and used the connecters to join the 3 conductors but now it is neither dust proof or water proof.These are probably actually M16 units that were mislabeled. I used it with 14 awg wires and it looks like it would handle a 10 awg wire with no issues.

I got these to install some lights at my parents house. We installed two separate outdoor lights that needed to be wired to the fuse box and I opted to run them both into one fuse to make it easier. This made the job super easy too, just insert each wire to the appropriate hole and tighten the screw down. After the caps were installed I used some rubber coated cable clamps to attach them to the wall since they have quite a bit of weight to them. I opted to use some silicone in each hole the wire runs into for the caps as I was using 3 individual wires and not a sleeved 3 conductor and there were small gaps around the wires. So far everything is working great and hopefully they last for several decades.

definitely waterproofthey work very welllittle persnickety to put togetherthey take some patience
