I purchased a reactor from Rex, with the CO2 tubing shoved through a small hole into the side. It has held for going on two years now, with absolutely no problems or leaks.
Two things, the tubing is a thick walled CO2 resistant tubing, not airline tubing. Also, the hole is significantly smaller than the tubing. So, use a quality tubing, and put it through the smallest hole possible, and you shouldn't have any problems.
