Duraball Pro Swiss Balls

What is “Anti-Burst”? 

It is very important to use a high-quality ball product that is actually “anti-burst” such as the DuraBall Pro Swiss Ball. 

This particular brand has been tested by the University of Newcastle engineering department, and if a puncture occurs, it will deflate slowly rather than burst. It is still possible for a  Dura Ball to get punctured, but the injury risk is much lower. 

The DuraBall Pro Swiss Ball is tested in a specially designed apparatus, which can progressively load a ball with a series of free weights. The test ball is then punctured with a very sharp, 10mm knife blade. 

A ball is deemed to be anti-burst when the cut in the ball does not expand from the size of the cut made by the blade. 

The manufacturer’s tests on the DuraBall Pro have exceeded a 500kg burst  resistance rating. This means that if you applied a dynamic load of  500kg to the ball and it suffered a puncture of any kind, it will deflate slowly. This gives a margin of safety to prevent injury in any use of the ball.
