The two above photos are of the same splice. The one on the right has the nylon jacket remove so you can see it's inner structure. In the photo on the left look at the area in the valley/window, see the half moon shape. This is why it is called a window splice. You can look it there and see the end of the wire strands after insertion and so can the FAA inspector.  Full insertion is important and you will be able to see that it has been accomplished with a window butt splice. Look closely at the photo on the right where you can see into the upper barrel- just above the valley.  That section of barrel has ridges in it that grip the wire when you crimp it Also note the double crimp area- the bell shape at the lower end of the barrel. That's the part that crimps on to the wire's insulation providing strain relief for the crimp connection area. This photo has a vinyl butt splice included in the pile for comparison. It's jacket is on the left. It's splice part is the one with the dimple.  First note how short it is. Secondly note...no window or double crimp sleeves. This one has the ridges inside because it is an AMP. The function of the dimple is as a wire stop during insertion. The very inexpensive vinyl products usually don't have the ridges or the dimple. The photo at the top of the page shows four types of splices.                                                                                                                 Vinyl 99 times out of 100 is opaque with a some what dull finish. The photo on the left is the vinyl splice I cut open for the above photo. It's very hard to tell if you have full insertion for the wire when it's opaque.   The single crimp nylon is a good general purpose connector. It is a better connector than vinyl because it doesn't crack when you crimp it and if it is of good quality ,  the metal crimp barrel will be longer. When buying any connector more metal is better. What I mean by that , is that the more metal the bigger the surface area that crimps to the wire. More metal means more money. Double crimp nylon is even better choice than vinyl and single crimp nylon.  It has the extra strain relief of a double crimp. But it is not Mil Spec. Mil Spec #7928/5  is double crimp and is a window butt splice. Mil Spec Nylon is always translucent.  Some nylon non- mil types are opaque and double crimp...a very good product, but not Mil Spec. The splice to the left is a Red 22/18 window butt splice. Nylon usually has a shiny finish. The Red 22/18 is some times pink...but it is still 22/18. The blue are usually a light blue. The same is true for the yellows.
