Haven’t installed them yet but they look like they’ll work as intendedInstalling a new power outlet for our trailer when parked on the property. Recently picked up the box and needed these to finish the job. They are a perfect fit in the box and breaker housing.They are simple to use and anyone can put them to the test. Just slip the threaded end into the opening in the box or housing and thread the nut onto the threaded portion where it came through. Slip the threaded cap over the tubing and slide the tubing under the fingers on the main body. Now just tighten the cap back onto the body and it seals securly. Run your wiring and connect it to the breakers and plug outlet.Came in an unmarked box with 6 parts inside. 3 straight and 3 90* ends. Made of PVC plastic that will handle the outdoor weather with no problems at all. I used one of each and now have 2 sets of spares for another project that is waiting to be completed.Very pleased with these and highly recommend them.These work great for both flexible and standard pipe to provide a liquid tight connection to a box. These are particularly useful if you need to periodically remove conduit.One of my applications is running sensor wires to a custom built water level sensor circuit in a sump pit. As this connector is submerged, it needs to be - and is - completely water tight. Every now and again I need to remove a length of 1/2 conduit attached to this connector which holds the level sensors in order to clean the basin. The conduit side simply needs to be twisted a bit and the conduit can be easily removed.The 90s need to be threaded on right to get the angle you want out of the box, other than that these are a breeze to install.The one being reviewed is the left one in the photo. Hard to believe I’m saying this, but the overall quality of the mold on these is so much better than the brand I got from HD (can’t remember the brand they sold). Appears to be the same identical materials, has the UP listing stamp and the seal is made of what appears to be rubber, but it is much softer than the yellow seal that came with the liquid-tite fitting from Home Depot. Honestly not sure which seal is better, but it fits the flex conduit the same and the metal nut holds securely in the box.
