The most common request from operators and measurement personnel that we encounter is 3% over pipe id. The next most requested is 2% over pipe id. These sizes account for at least 95% of sphere request. Both provide good seal and function. On larger provers, balls are sometimes sized larger to account for pipe tolerances.
