You'll need Grade T hose for the propane...and when I bought mine from the welding supply store it came with an oxygen hose.
THEN you need a Y connector to connect your oxy cons to the oxygen hose. Is that what you're inquiring about? The welding supply store probably won't carry one.. but they might carry the supplies to make one if you want to go that way - or the local hardware store.
Here's a link to that subject -

The oxycon is connected to the Y connector.. the Y connector is connected to the oxygen line (green) and the oxygen line is connected to the oxygen port on your torch. sing this to your welding supply guy.. he'll get it.
Good luck!
