For the last four months I have been plagued with flat tires. I have put 10 plugs in my tires in that time period. I actually did three in four consecutive days, and over the course of all this, have replaced two of my four tires.
I've got a buddy who is into rock crawlers. A couple of years ago, I noticed that he had some some of small air cylinder strapped to the roll cage of his buggy and asked him about it. He told me this was a nitrogen tank and could fill all four tires from 10 psi (which is what they air down to for max traction) back up to 30 psi.
Fast forward to last week after my tenth gas station emergency tire plugging last Friday evening at 7pm when I'm trying to go home is when I remembered about the small on board air cylinder on my buddies rock crawler.
So I call my rock crawler buddy and ask for specifics. They use what's known as five pound CO2 tanks. These tanks are about the size of a three liter coke bottle. But for my needs he suggested something a little smaller and he gave me a 20 ounce refillable CO2 cylinder that is used in paintball guns. This can be refilled at academy or dicks sporting goods for a few dollars. He didn't know exactly how to use this cylinder since the threaded valve is different than the standard CO2 valve on his tank, but he assured me it would work.
After about a half days worth of google searching, I am in business.
Here's a pic and listed below are the exact parts I bought online. FYI: the first brass valve on top of the tank is part of the tank, I purchased two parts that are installed inline above that point beginning with the blue adapter.
The blue fitting is a "paintball-to-CGA320 adapter" - http://www.amazon.com/dp/B004M49QDC/ref ... 25410_item
The tall brass regulator on top of the blue adapter is a "preset 125 psi CO2 regulator" - https://weldingsupply.com/cgi-bin/einst ... D:RP320125
Sticking out of the side is a standard quick detach air chuck that you can hook up a regular air hose/tire chuck to use to inflate your tire.
So to test this thing out, I pulled my valve stem on one tire and let the tire deflate all the way to zero. Re-installed valve stem, hooked up my air hose to the CO2 and let her rip. About two - three minutes later it became evident that the CO2 cylinder was about empty, but amazingly did it's job completely. I was able to get 36 PSI into my standard sized GMC pickup tire with one 20 ounce paintball cylinder. I don't know for a fact that my paintball cylinder was even completely full when it was given to me? Regardless, there was enough power in that cylinder to completely fill one tire. Most of my recent tire repairs have not even been on a completely flat tire before I made the repair, so this should be a long lasting device???? All this is small enough to keep in my tool box for emergency backwoods tire repairs.
I hope this is helpful to someone else who may be plagued with tire punctures like I seem to be?? You could also run a nail gun or blower nozzle, etc with this set-up. Back when I used to trim houses and had a call back to fix one little thing, this would have been too easy to use to nail up that one missing piece of moulding and be done with it, rather than hooking up air compressors, running extension cords, etc.
Cheers!!
(PS - USE THIS AT YOUR OWN RISK!! I have no idea how safe this contraption is. I think those CO2 cylinders are pressurized to about 1000-1500 psi??)
You can plumb in quick disconnects at the bumpers or have one at the tank and a hose to reach.
