Portafilter Double Spout Problems - any suggestions?

So, we have not had any problems with our portafilters on any of our Nuova Simonelli espresso machines in the past but we just bought 2 new machines and the trouble began.

When we put the double spouts on each portafilter, they turn past center and end up being sideways (shot classes would be front and back and not side to side).

Before I tell you what I have tried, do you have any suggestions? It is about to drive me mad.

Also, before I get tons of posts about using naked portafilters in stead - we have thought about it but because we do catering and at times use small (8 oz cups), we need to be able to do singles.

Thanks for your help!

Thanks for the help guys. I am going to find some automotive o rings as I have heard many success stories...

I just use automotive O rings on my porta filters. They do wear out though, so have some handy....

Well, if you feel crafty I suppose you could remove some of the threads. Or possibly a different spout? I think I would take some of the threads off if it were me but I like to mess with things. A safer bet might be to put an o-ring on the male thread and hopefully it would take up the necessary space to straighten things out. It's not a pressure sensitive place so it doesn't need to be torqued up.

The portafilter is straight in the group head. It is the spouts that you thread on that basically tighten an extra half or quarter turn. It is almost like there are extra threads....

I'm not familiar with Nuova Simonelli specifics, but with other brands I have worked with(la marzocco, la cimbali), you can correct this through placing a very affordable shim above the group head gasket effectively lowering the gasket and making it engage earlier in the rotation and more straightforward. You can also get different shaped gaskets sometimes. I'd suggest calling espressoparts or checking out the catalog and seeing what is available. They would definitely know.

You know, we had the same problems with our new ones as well. We pretty much just adapted to it. I know its not the best option but thats what we did. I honestly was just being lazy and didnt feel like trying to fix it.
