What I'm looking for comes in the Platypus Drink Tube kit, but I don't need the whole thing. Seen at the end of the tube here: http://m.backcountry.com/platypus-drinking-tube-kit
What I want to do is use this piece in conjunction with an inch of hose and a female quick connect valve in order to clip my filter hose directly into the top of a platy bottle, not bladder. I would switch the regular cap with this for refills. It'd enable me not to have to hold my bottle while filtering and just generally be convenient and cheap. Any ideas?
