Ok thank you, I was planning on using your 4mm ID hose and the push in 8mm x FFL and 5/8 fittings that you do have in stock (not the duolock, these ones are the metal ones), I have just updated my cart to include your 5mm ID hose and clamps, to enable me to use the existing ball valves and tails. I figured the 5mm ID hose would be easier to fit to the 6mm barbs than mucking around with 4mm ID on those, and I will just keep the 4mm ID hose to run to my taps.You would need to remove the entire 1/4" Ball Valve and install a 1/4" Gas Ball Lock Bulkhead.
Yes that is correct. You can unscrew the 1/4inch ball valve and fit in any of the push lock fittings.
Do you mean the Duotight push in fittings? We do not currently have a Duotight push in fitting however we do have some new 1/4inch Duotight fittings available in about 3 weeks that will look similar to this however will have male 1/4inch thread on them so you can use them with the manifold:
