I have a toilet shut-off valve that I want to install. It has a compression fitting on the valve outlet that goes to the toilet bowl. I notice that the compression ring (sleeve) shape is not exactly symmetrical, so I'm thinking that the compression sleeve has to be installed in a specific orientation.
Which end goes toward the compression nut? The HD guy said it doesn't matter. I'm skeptical of that.
The compression nut should bear on the short taper to provide maximum force on the long taper to seal against both the tubing and the outlet hole. From a practical standpoint, perhaps many hundreds have been installed in reverse and work just fine. Using it the way it was designed gives you better odds for success IMO.

The brass rings for copper tubes are symmetrical and can be installed either way. I have seen the plastic rings for plastic supply tubes that have a wedge cross section, in these you put the flat portion towards the nut so that the thin edge jams in between the pipe and the valve fitting to seal it.
Thanks to Joe and EXT for the comments.
