hmmm...would have to look into that. I have a handfull I've collected from various jobs over the last few years but I've never bought them as a stand-alone part. I believe you're looking for a 6mm Voss fitting. A quick google shows lots of options in England/Europe but nothing here in the US. I'm sure they are available, it will just take a little searching.c
I've kept all my old fittings from buying other stuff; you can often re-use them so I keep the old parts as spares when possible. Plus I never installed the GOE kit I bought like 3 years ago, instead it's become an expensive spare parts inventory for air stuff.
In a pinch I could loan you a few to take in your spares kit 'just in case'.
