Q: New to the duotight world. I have a question about using the 4mm duotight on a SANKE adapter (beer / gas) nuts. When I disconnect the nuts from the keys do I need to undo the hose, or is it okay to spin the nut on the hose?

A: The beauty of the Duotight connectors is the ease of disconnecting the EVABarrier tubing. I recommend removing the tubing before unscrewing the adapter. All you need to do to remove the tubing, just push the tubing into the adapter, then hold down the ring where the tubing goes into the adapter and pull the tubing out. If you plan on removing and installing the tubing often, you will want to put a small amount of Keg Lube (D52) on the outside of the tubing to aid assembly and disassembly.

Q: Will Star San (1 oz/gal solution) degrade this tubing if it sits in these lines for a prolonged period of time, or will it not do so the same way it can to vinyl tubing?

A: EvaBarrier tubing should be very resistent to diluted Star San.

Q: The ID for 4mm line is a smaller diameter then 3/16. Why does it have a lower flow resistance? 3/16 = 3.0 lbs/ft Your description states: 4mm or 5/32 = 2.8 lbs/ft

A: The 4mm inner diameter EVA barrier tubing has approximately of 2.8 pounds of resistance per foot. The 5mm inner diameter EVA barrier tubing has approximately one pound of resistance per foot.

Q: Can this be used for both gas & liquid connections? Or should I use item # Z92 I want to use a line with the most O2 barrier protection as possible. So thinking this one would have a thicker barrier. Just not sure if its designed for the gas side

A: It can be used for either side, and will flow plenty of gas for a typical home draft system.
