We blew out several hoses (with a crack like a .22) during practice for rebound rumble. We had a pneumatic climber, but we didn't even have the climber attached yet. We were just making adjustments to the Frisbee primer that required depressurizing the system. In filling up our (seven?) plastic tanks, we blew out the hose at the end nearest the compressor. The large quantity of air depressurizing through the rupture cooled the tubing back down, so it took us several swaps to figure out that it wasn't just defective tubing. This was followed by closer monitoring to figure out the actual cause. Our solution was to relocate as much of the brass as possible to before the first piece of tubing, and continued monitoring for swollen tubing.

Emphasis mine. I said Competition Bot. We use a different compressor that is rated for 100% duty on the practice bot, but use the VIAIR 90C on the competition bot for the obvious weight savings. Nearly our entire bot was pneumatic, and the 90C was capable to compressing for nearly 20 minutes straight before we ever had a blow out. (not that I recommend it)

On the practice bot, we use either a Thomas 215 or another who's name escapes me.

Also, if your tubing was blowing out from only filling 7 (assuming black Clippard?) tanks you may want to re-evaluate both the fittings and tubing you are using. I know in our case, we have melted the O-rings within the 1/4 pneumatic quick connects (but this is after 30+ minutes of running and the crappy FIRST Choice connectors)

Or add a fan.

We use Freelin-Wade tubing, and SMC pneumatic fittings.
