High quality ball only pressure gauge.

Over-inflation pressure release button.

INFLATION: All Molten balls have the correct pressure printed around the value.  Correct ball inflation is important to maintain a technically superior ball.  Over-inflation will damage the ball.  When inflating the ball with a pump it is critical the needle is lubricated before insertion. This helps to prevent damage to the valve and avoids unwanted air leakage.  It also makes needle insertion easier!
