Per Kevin Arthur "Each pipe has an open airway of 5/32" from bowl to stem. All stems have an open airway that tapers from 5/32" to 5/64" and are funneled and trumpeted at the button. The stem thickness at the button is approximately 4mm or slightly thicker for larger pipes and very comfortable. I use Delrin tenons exclusively on all pipes".
