What gas is in tennis balls?

Pressurized tennis balls are filled with either air or nitrogen, with nitrogen keeping the balls inflated longer. On the other hand, non-pressurized balls are solid, which keeps them from deflating. However, non-pressurized tennis balls wear and tear at a quicker rate than pressurized balls.

Why do tennis balls go dead?

You might be surprised to know that a sealed or unopened can of pressurised tennis balls won't last forever. In fact, an unopened can of tennis balls will usually last around 2 years unopened. That's because the pressure in a can of tennis balls will slowly leak out over time through micro leaks in the packaging.

How do you Repressurise a tennis ball?

Repressurization can be done at pressures from 24 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 three weeks. When they are ready, pull the pressure release ring located in the new tank lid until all pressure is released.
