I don't know how it is your, but on my old DIY the CL was connected with a quick connect to a 90° plastic pipe: on the top of this pipe I mounted the PPort with Dräger connections: I did read the O2 on the exhale CL, just prior the breathing hose. It did work well, no leaks.

Hope this help.

No the leak prob is between CL "matérial" and the two parts of the female p port

Did you ever try to pressurize the CL to see for any tiny hole?
Or maybe the two parts do not really match together.

You need a gasket between the flange of the p-port and the bag. Get some sheet neoprene (the solid stuff not foam neoprene like wetsuit material) and cut a large disc with a hole in the middle for the threaded part of the p-port. You can either buy this (I got a pack of 5 sheets from RS Components, very useful stuff rswww.com) or cut it from a piece of inner tube. If you try to tighten a p-port straight on to a waterbag without a gasket then it will leak.

Also make sure that the hole is not cut to big, the threaded part of the p-port should be a tight fit in the hole or it will leak.
