I worked for Parker Hannifin for several years designing products in their brass fittings division and we utilized a large group of their PTC fitting line in our product. I'd have to dig to find it if I still can, but the rating used to be on the product catalog main page. When you insert the tubing, the proper method is to insert fully and they'll tug to seat the barbs. This deform the barbs a little bit. After being done a few times the barbs no long hold a perfect shape. The metal that makes up the barb itself is only a few thousands thick and won't hold shape for long when being deformed back and forth. I'll see if I can find the spec and get back to you.
The orings just get torn up if your tubing isn't cut properly...
