Good product just wasn’t what I needed. I needed one for paintball machine. I don’t know what I was thinking. I accidentally clicked on that one thinking it was for paintball gun

Product will work as intended and described...HOWEVER... buyer BEWARE!!!One of the reviews prior to mine also said the same thing I am about to:To get this to work on my bottle took a fair amount of work with an appropriate file. The first pic shows the distance it screwed on without the white nylon washer. Pics 2 & 3 show the file work that was done. Had to file off the bottom of the last thread toward the bottle, file down the diameter of the rest of the threads, then use a flat small file to file down the chamfer on the remaining threads. After that, I had to screw and unscrew...screw and unscrew with some force for about 40-50 times (as was said in another review as well). After all that FINALLY it seated all the way on the bottle as shown in the 4th pic. The fifth pic is with the white nylon washer installed. Yes, it works. yes it does the job....YES...you will likely need to do the same work as myself and the other reviewer did.Happy bubbles!

I bought this so I could use my old SodaStream bottle to hold some compressed air. The adapter screwed on, but not far enough for the pin to open the valve. After some filing on the bottle threads and much work screwing the Adapter on and off 40 or 50 times I was able to get it on far enough to operate properly.

This fill adapter is for type TR21-4 thread cylinders as the standard SodaStream (SS) cylinder or CO2 cylinders with a SS adapter (as pictured).You fill the CO2 gas through the 8mm fill nipple while you can monitor the fill with the 3000psi pressure gauge. After filling, simply shut the source CO2 tank and purge residual gas with the bleed vent.Seems to be made with good quality materials. One small spare seal gasket is included.
