Reusing 5l keg cans?

Has anyone ever tried this? I just finished a 5l keg of Newcastle. I ripped out the dip tube and managed to keep the hole in pretty good shape. There's something banging around inside, though. I have no idea what it is and I'm not sure if I can get it out without completely ripping the top off. Any ideas? Has anyone figured out a way to make use of these?



I also have a Kulmbacher Edelherb 5L keg. It's got a hole in the top and a spout at the base. I don't want to ruin the hole in the base by ripping the spout out. I'm not sure what my other options are for using it.

It's reusable. Get a replaceable bung with the black rubber/red plastic key.

Any more details? Like where to find them maybe? I did a search and couldn't find any information.

You are looking for a 2 piece bung. The ones I have are grey rubber with a plastic piece you push into the keg and retrieve later.

These bungs will work for the kulmbacher keg but the newcastle leg looks like the heineken style. As fas as I know there is not a bung for those type.

you can't reuse the newcastle one...its just like the heineken kegs...there is a co2 device inside and you can't remove it without destroying the keg.
