Asura2sec Enclosed CO2 Tire Inflator for Unthreaded CO2 cartridges

I was concerned with the quality when I made the purchased, but this is easily the highest quality and easiest to use inflator that Ive ever owned. It fits easily under my seat but comes with an adapter for your frame that I havent tried yet. I have some older CO2 cartridges that do hit the pin when the inflator is fully tightened because they are shorter, but I simply packed cotton balls into the bottom of the tube and it worked perfectly. Very happy with this purchase.

If using unthreaded CO2 (eg. Crossman) put 2 cents in the canister to push cartridge enough to puncture.

This inflator is well made but it doesn’t work. I doubt that they did any real testing when they designed it. The 16g CO2 cartridges don’t fit. The cartridge housing is just a little too long. It makes a mark on the cartridge but doesn’t penetrate. One more thing for the landfill.

I'm so glad I bought this little inflator I was in the middle of the Woods and hit a stick I was able to repair my tire and fill it up quick and get out of there as fast as I could

My last inflator broke, but I still have a lot of the cartridges left so I went looking specifically for an inflator that would fit the size and style of my cartridges, which this one specifically says it does in the description. However it looks to be the wrong style again, as from the interior this seems to be for threaded cartridges. Threadless do not fit, the neck is not long enough to reach. It will depress and leave a mark but will not puncture.The overall design is nice, the lever instead of trigger design is good for tight spaces, and it screwed onto the valve effortlessly. It simply does not fit the needs at advertised.

I’ve purchased 3 or 4 of these and the price is right. Quality is lacking consistency. The 1st one o had was great and lead me to buy a 2nd. That one had a valve and gasket failure which was partially my fault. The 1st one finally wore out the puncture needle inside so I replaced them both with new ones. Well the same Co2’s I was using are now magically shorter in these not allowing the needle to puncture the cartridge. Easy fix just glued a dime in the bottom. Both of these the handles broke. Also the seals failed very fast leading it to leak air once the cartridge was punctured. Overall I liked the product but had too many failures so close together. I can’t purchase any more.

I actually used this with 12G unthreaded CO² cartridges. I put a penny and a silicone washer in the bottom of the tube and have used it 6 times without issue.

It stated you can’t use threaded c02s in it, but it worked! I still have to get some threadless ones. Cheaper and available at local stores.
