Review: The thread is incorrect for the co2 gas cylinder in new zealand
Review: Update: Purchased this to use in conjunction with a Vevor 5 LB CO2 tank. It worked perfectly to hook up to my iGulu brewing machine. The pressure meters matches between the one on this adapter and the one on my machine. As far as I can tell so far there are no leaks, and it was as simple as screwing it in. It came in a box with directions as well as extra parts. After using it for a while I found that it was actually leaking a small amount resulting in the 5Lb tank draining far quicker than it should have. Looking close I found that one of the yellow brackets was cracked and the hose under it looked like it had been crushed. I contacted the seller and let them know and they sent me out a replacement right away. The replacement looks perfect and appears to be working well so far. The steps that come with the directions are not correct and indicate washers need to be inserted when they already come that way. Highly recommend both the product and the seller for their quick and prompt support.

## Questions & Answers

**Q: Cn this be used for a sodastrem 60l co2 cartdri?ge**
A: To refill the bottles, you will have to also get this item.  
https://www.amazon.com/gp/product/B08B4RGT2W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I bought the other item first to refill my bottles and this bought this item to run my Soda stream directly off of a bigger bottle. That did not work as the pressure was too high. The ends of both kist are Quick Detach so I just swapped them. The biggest thing you need to know is the Soda Stream bottles have a safety valve inside them that shuts off if you fill the bottles too fast. Filling it slowly is the key. I use a food scale to see that the bottle is getting heavier and also gauge how much CO2 I am putting in the bottle as it only holds 14.5 ounces of gas. Don't overfill it or the relief valve will pop rendering the bottle useless.

**Q: Do you have to turn the gas off at the tank between uses or can you leave it on all the time?**
A: I've had an instance when the tank leaked to empty. So I close the valve when I'm done using it.

**Q: My Co2 tank has a siphon tube. Will this still work?**
A: I use this with a siphon for a while. However I think it caused the gas to freeze and clog and break the infuser. I was going to kill my 10lb Tank and switch to a non- siphon tube one but guess I’ll have to do that sooner then I thought.

**Q: I'm looking for a longer hose than the 5ft one which came with this kit. Any tips where to find a 10 ft hose?**
A: This vendor offers longer hoses, check in with them.

me gusto bastante, la manguera es muy delgada pero se ve muy resistente se le nota el trenzado metálico para aguantar la presión del tanque de Co2
