Carbing in a D style keg

[Medevac_Chief]

Just have a quick question, I am planning on using a commercial style keg to put my next batch in. Does any one have an idea on how to keep the CO2 in the keg without beer coming out the top of the coupler? Thanks in advace

the top of the coupler would be hooked to the beer line

You can put the rubber washer over the port where the tailpiece would normally be, top it with a dime or penny, and then tighten the hex nut down on it. Or you can connect the coupler to a beer line with a closed faucet at the other end.
