Appion has been a very good line for us. We modified the Appion kit to eliminate the manifold and have had a lot of success with this kit. It is a great kit for residential and light commercial, up to about 75 tons. The Appion manifold is great when you have a larger commercial system with a lot of access ports. With that manifold you can connect 2) 1/2" hoses and 2) 3/8" hoses to the system. You can use the manifold for smaller systems also, but we found it better and more cost effective to only use it when you need it. The core tools can be used to isolate the vacuum rig when you charge the system.
Can and would being two different things, I would not as the hoses would hold a ton of refrigerant. I would bet a 6' 1/2' hose could hold a 1/4 to 1/2 pound of liquid refrigerant. I do have the manifold and I use it only for recovery. The Megaflow kit works well for that also as we have the same issues with vapor recovery after the liquid is out that we have with removing air. Using the G5 twin with the Megaflow kit is as impressive as seeing in in action in an evacuation. I took 14 lbs of 404a from a system in under 8 minutes and had it down to 10" of vacuum.
I use the Mega flow kit, TEZ8, and the SMAN4 for microns. I can pull a 30 ton R-22 PCA down below 500 microns in 45-60 minutes and change the vacuum pump oil in seconds if it gets saturated. They are both well worth the money.
