hard to tell by that small pic - but my guess is NO - that won't work unless you heavliy alter it. Again - it's too hard to tell if it even has the 4 nubs and 9 smaller ribs between each nub.
With the one i found - there is a separating piece on the actual item (it's used to reduce the hole size from a 1" to 3/4" hose) that would go behind the vest.
the one you show does not have this, but rather has a huge pipe thing that would have to be cut off or you would have a big ole pipe in yer vest (ouch). I dunno... find a better picture and we'll see
