Hey guys!

I have just bought some stainless steel disconnects, and I've noticed they have three balls underneath, as opposed to the plastic ones that have four.

Am I right in thinking that the stainless ones won't fit the stainless carbonation caps on the fermzilla? They only seem to fit on the 'proper' style keg posts that I have on my fermenter king juniors.

Also, regarding the black plastic disconnects, all of a sudden they are jamming and won't fit of any of the liquid sides on my kegs / fermzillas. The gas ones are ok, it's just the black beer ones. I've changed the o-rings on the carbonation caps in case it was that, but it's still the same. What's going on? It's a massive fight every time we want to get one on or off. I've ordered some new ones in desperation, as don't know what else to do!

Yes I'm putting them on the correct side, in case anyone is wondering.

Can anyone help please?
 
Have you changed the o rings on the posts? Whenever this happens to me, that is nearly always the remedy. If you have done this and it still isn't going on smooth, try a little bit of lube around the post and inside the disconnect.

But the issue could come back if you are using cheap disconnects. They are not all made the same. Check the inside for shrink marks. The problem you are having kept happening to me. I threw away my non branded disconnects and replaced them with kegland ones.

Yes I've changed the O-rings, as I mentioned above.

I've ordered the 'premium' ones at £7 each from TMM - hopefully they'll be better then. Thanks Phil

Hi Tess the black beer outlet get gummed up with beer so rinse them under the tap and pull back the clip to get the beer out of the ball bearing area, I then use a food grade lube or KY jelly on the posts and they should be as good as new

I mean they get soaked in PBW and then hot water after each use so I was assuming that would be enough cleaning wise - I take your point though that there may be some sticky **** lurking somewhere.

I wanted to get rid of them all and use stainless steel but the damn things don't fit. Also you don't need a screwdriver to take them apart.
 
you know the collars that comes back pull it back and rotate/turn it at the same time to dislodge any sticky goo, you will feel the collar going back further as it frees the dried on beer residue
 
Baron you are a genius! Thank you! I was trying to connect my tap to my pressure bottle so I could flush it out with sanitiser.

Strange that the SS disconnects won't fit on the fermzilla posts, which I assume are universal posts?

I thought it strange too. They won't even go halfway on. Perhaps I'm doing something wrong?

The different ball bearing setup underneath is throwing me off as well. Perhaps someone has experience of fitting these and can let me know.
 
It really shouldn't make a difference with annular shapes. I can only assume that there is something about the uni posts that they don't like. Bit of a long shot but what is the depth of the inside of both sets of disconnects and also the depth of the grooves on the standard posts Vs the uni posts?
