Keg is leaking beer

[jopaul]

I just bought a Summit SB500 kegerator, and with my first 1/4 keg I am experiencing a beer leak. The leak is occuring at the point where the beer tube connects to the tap. My question is, do most beer tubes have use rubber washer that connects to the tap? Mine only came with a wingnut, but I thnk I am missing a piece that would prevent the leak.

Any help would be appreciated. Thanks.

there is a washer that connects between the line and the tapper. I forgot to install mine when I got my unit and it will leak bad. Install one and u r ready for some ice cold suds.
