I just got this. It’s a beer keg with an oval top. Smart idea. But, the beer keg says max pressure 60PSI, the cap says max pressure 130PSI. Might want to get those numbers aligned.
It's important to note that this tennis ball wears out over time. The outer cotton cloth deteriorates, leaving behind a hard rubber ball that can be tough on your hands and may even increase the risk of arm injuries. Additionally, the recommended pressure of 40 psi is quite high and may cause the ball to become heavier and harder on your hands after 3-4 weeks. It's essential to consider these factors for your safety and comfort.
@@miamicane2008 I recommend listening to the manufacturer and not someone who thinks tennis balls are covered in cotton cloth. It's felt. The higher pressure reduces the time it takes to repressurize the balls. You aren't going to end up with 40 psi balls. They'll go back to normal pressure quickly.
