the common cappers fit around the necks fine, the trouble is the bottom of the capper, the jaws that close around the bell shaped part, need to latch on to the ridge that is a little down from the bottle lip. The capper won't pull itself and the lid down tightly without that. bottles like dos equis, founders, anchor, have a ridge that is not far enough down for the jaws to grip it.
you can get a watertight seal, but its a risk it won't hold the pressure. i'd practice it a bit before risking a bunch of beer
