These are made by DIG and are quite impressive and different than other "twist" lock type connectors. The bevel the tube pushes over is very Sharp and intended to dig into and grip the tubing tight.It is also removable - important feature as you will see. The nut lock is much stronger overall and more precisely manufactured. It has more threads per inch on the nut so it can be really torqued down and wont move. It is semi-permanent! The fitting with the bevel is removable. If you want to remove one of these you wont be able to remove the tubing except to cut it (or heat it up well and wiggle it out). Point is this a far more secure fitting suitable for burial if needed. The difficulty of removing one is really not an issue though. Since the part with the bevel comes out you would just pop out a T and replace it with a coupler leaving the bevel parts in place. Its only if you wanted to take out the nut lock type and use another type then you got a tougher job. They are bit larger and more expensive to it depends on what the need is if you go this way or not. THey look like a good choice for the part of the circuit you are confident wont change much.
