Pressure Refresher - 10 LB CO2 Charging Kit

Drop any number of tennis balls up to 60 into the pressurization tank and reinstall the lid. The schrader valve allows easy pressurization with any air compressor or bicycle pump. Repressurization can be done at pressures from 32 psi to 50 psi depending on the time balls remain under pressure and the amount of bounce you desire. This process takes between three days and two weeks. When they are ready, pull the pressure release ring located in the new tank lid until all pressure is released. Then open the top and begin to enjoy your freshly repressurized tennis balls. After playing, the balls can be stored in the tank at 16-19 psi so that they will retain their internal pressure. This unit is made from a used keg that has been cleaned and refurbished with new seals. While it may show some wear, our price certainly beats the $450 unit that is available elsewhere. This unit is also safe to use thanks to industrial grade parts and specially machined stainless steel fittings that are made to hold pressure. No parts are hammered together and held with glue and tape like some homemade units we have seen.
