Hi, I was just wondering if the 12mm enhance rotary fittings were compatible with your 12mm brass hard tubing? Or would the advanced fittings be better? I Prefer the look of the enhanced fittings if they are compatible, also if i was to make a relatively large order of fittings what would the estimated delivery date be? I'm aiming to get them before christmas but would understand if that would not be possible. Thanks
Kind regards,
David
