Actually, it would be almost impossible to have a grip explode during air install...the protective tube is used when REMOVING a grip with air....because THATS when it is most likely for a grip to explode.
Remember, gripping tape is NOT meant to increase grip stability, but it assist the grip to slide on easier during install. With Air, tape is unnecessary unless for fitting purposes.
There are a few grips out there by certain manufacturers that I've seen that you actually do have to use a layer of masking tape on because they're not exactly .580 or .600. Those grips always slip a little unless you put one layer of tape. Don't know why, but they do. Might be a QC problem, who knows. But there are grips that need a layer of tape.
Oh, and for those of you interested in using compressed air, Pure is doing nothing new. I've been blowing grips on for years, as have a bunch of other people. Instead of going and paying out the butt for a "air grip install gun" that they sell, do yourself a favor and visit a local hardware store or harbor freight. http://www.harborfre...zzle-42939.html
That's what you need. If you want the sleeve for protection (I never use the one I made, and I've exploded grips before. It doesn't hurt long.)get a scrap piece of 1" PVC with a cap and drill a hole in the end of it to accommodate the threads. Then take a countersinking bit and chamfer the edges just a bit. Put the blow gun nozzle's threads through the cap and tighten it. Then all you do to use the sleeve is to slip it over the grip, put the nozzle through down to the base where the cap it, and slide the PVC in place. You'll want about 10 inches of PVC so it covers the whole grip.
