Yup, it's a tap for the barbs I use, 16x1.5, it's Fette PM edition ISO 2, 6H, I don't claim that I know what all that mean. I found it on their site under product no 1394474, but cannot get the price for the new one, I don't wanna register just for that.
All I know is that in shops here, ordinary one, without the TIN coating, 16x1.5 tap is priced around 40$...
Sry guys, I just had to post it
Cheers!
