Calculate the recommended ring end gap from the chart above. This allows the mounting operation and ensures a radial force toward the cylinder liner. It is cylindrical in shape and reciprocates inside the cylinder. Most conventional ring sets are purposely left a bit tight and must be file-fit by hand to achieve the proper amount of end gap for a particular combination. A ring must have a split in it to allow installation on the piston, but also to provide room for expansion. If you use percentage grades, have grades on a different scale or in high school with AP/IB classes, please change the "Settings" to input specific values. This allows the extrusion gap to be smaller for tight-tolerance wear rings, thus increasing the seal's pressure rating beyond what it is rated when used with standard-tolerance (+/-.
