    rubber plugs for CO2 tank

    I used to work for a swimming pool service company. We would use a CO2 tank with a hose and rubber plug to blow out clogs in lines. Does anyone know where I can get some hose and the rubber plugs? The plugs allow air from the tank through the center of them and they have a compression wingnut you tighten to make it fit securely in the pipe. I cannot find the plugs and I have googled for days. I can find all sorts of rubber plugs and plugs with holes in them, but not the kind that has a hose connector on the top, a wingnut and allow air through the center. any help would be greatly appreciated.

    It was probably custom made. You can make one with the proper parts. A bulkhead fitting and a winterizing plug and some drilling.

    What you seek is called a purge plug, and they are commonly used in pipe welding to fill pipes with argon for welding and such. Here's a link - http://www.techsouthinc.com/purge/tspurge.html #disclaimer - I don't know these folks, just found them on the internet.

    I knew there was a special name for them. It was bugging me like whenyou know the name of an actor but can't think of it. Thanks so much

    No problem. You might find something by looking for hollow stem test plug, or some such, but I've always known them as purge plugs.
