Charts

The charts below provide resources for Chemical Compatibility, Mesh and Micron conversions, and Pressure Equivalents. You can use the Chemical Compatibility chart to evaluate Pneuline materials and different grades of plastic, while the Mesh and Micron conversion chart helps compare particle sizes. The Pressure chart offers English-to-Metric equivalents, and we also include detailed check valve flow data. Most importantly, we now feature our new flow and crack pressure test results, giving you enhanced insight into valve performance and reliability.
