Yes these are already on the water so this arrival date for the
duotight ball lock disconnects should be pretty reliable. We are also going to release a 1/4 push in type and also have a 1/4 OD (6.35mm) x 3mm ID Evabarrier Beer Line too. Previously we did not make Evabarrier under 4mm ID but this new 3mm ID type gives really high flow resistance so if you want really neat and short beer lines it's a good option. The duotight 1/4 push in disconnects should be available in about December. We will also get the 3/8" (9.5mm) duotight ball lock disconnects too and these are a really good option for longer draw systems or when you want to make transfer lines to transfer from fermenter to keg. The extra large diameter makes the flow rate much higher.
With the price breaks we do already have a x6 price break on the duotight ball lock disconnects so if you get the x10 the x6 price break will automatically be applied.
