I stopped by a trade show today at a local parts warehouse and saw these there, pretty awesome stuff. The guys who had the booth pressurized a piece of PVC to over 1100 pounds(yeah, I didn't believe it either until I saw it.) with the fittings on both sides. Other fittings blew from anywhere around 850-1000. No glue, and doesn't matter if the water is running. All they have right now is 1" and 3/4", but said they should have larger sizes soon. I'll post pictures tomorrow, I forgot the fittings in my buddies truck when we left. Has anybody else seen these or used them yet?
