SimlugSoda Adapter, TR21-4 Male Thread Brass Soda Water Adapter Connector Accessories for Club

I bought this as a replacement for a cheap adapter that came with my hose. So far this one has held up great, probably ran 50 or 60 bottles through it and it hasn't leaked at all (yet).

I bought this to replace another failed adapter, and while it was working perfectly for a whole two months, it started acting up where no CO2 would be let through the valve when trying to carbonize water.Even removing it from my machine, I could not manually push the pin down to release the line pressure, indicating the problem was inside the adapter.Once I got it off the line, I used a vice and pipe wrench to take it apart. You can see in the picture the seal is all chewed up and deformed. (Donut shaped) This created a blockage and was preventing gas from making it around the pin and seal.TOTAL JUNK!It feels absolutely wonderful to throw my money away buying this total junk....

Like other reviewers, I bought this to replace a failed part that came with another kit. Looks better made than the original.

Used this to replace another adapter on hose connected to carbonator. Only worked once. Then wouldn't release gas again after that. Guess the pin became stuck and wouldn't allow carbonator to press it. Went back to original adapter and that works fine. Sending this one back to amazon

This is working well to replace a broken component of another adapter listed on amazon.

Leaks CO2.

Quality is 5 stars, but I was unable to find a female TR21-4 quick connect fitting in three local stores (one had literally 100+ different brass fittings). I ended up having to remove the silver piece which leaves a 1/8th female pipe thread which is fairly standard. This was shipped from Asia so perhaps you will have an easier time finding the fitting in that part of the world.Removing the silver piece requires a vice as they've used red Loctite to seal it into the brass coupling. Be careful as there are two pieces which will fall out: a spring, and the silver plunger which you can see poking through the CGA320.It would be great if this was offered with a different connection option (such as a 5/16th flare thread).

I was really hoping this would work, but after a little over a month the seal inside destroyed itself and it doesn't let the gas through with the pin pushed. Looking for a better option.
