An ultra low pressure regulator controls internal air pressure at extremely low levels — as low as below 1 inch of water — during the free extrusion of plastic tubing. This precision is essential for thin-wall tubing because even minor pressure fluctuations can cause dimensional inconsistencies in the outside diameter, wall thickness, and lumen structure of the finished tube.
