Description Sometimes the sports balls like basketballs and football will burst if they are over-inflated because of the high inner air pressure. But how to prevent over-inflation of the inflatable balls? The most important thing is that we need to control the ball pressure. This ball pressure gauge is just such a tool to check and get accurate readings of the ball inner pressure. It is equipped with an air release valve, which allows you to easily release air to adjust pressure of over inflated balls without removing the gauge. The dial gives both PSI and Bar readings for convenient use. Suitable for volleyballs, basketballs, football, soccer and all other inflatable sports balls.
