Everything fine, thank you very much
Have took set of 2 fittings for connection of hose to Tap. All are work but i need the last gasket between these parts. Tip at photo has outside dia 6mm and 6mm inside dia of hose - the one fits good, but could to take up to 8mm tip because the silicone has good strechtening. In total the set fits good for M22 external thread of taps. I will be synthesize ethanol (not for drink).
