This specialty wrench is very important in reducing Co2 loss. The majority of the calls we receive from customers who lost their gas pressure in their tanks is directly related to not tightening the regulator down enough to the tank valve. Considering an average Co2 fill will run you between $12.00 and $18.00, investing in one of these wrenches can save you money in the long run.
One end fits Co2 nut and the other end fits the regulator bonnet.
