O-ring Groove Design
Welcome to our O-ring Groove Design section
Here you will find an O-ring groove design guide to help you with your O-ring gland dimensions. Through our extensive research we believe that these O-ring groove dimensions and fit details will provide the optimum O-ring compression squeeze for your seal to prevent O-ring leaks. Based on the cross section (CS) of your O-ring, you will choose the corresponding O-ring groove depth and O-ring groove width dimensions. The O-ring inner diameter (ID) should also stretch approximately 5% over your groove or gland. If you have a custom O-ring size that does not appear on this chart, contact us directly and we can help you size your O-ring gland design accordingly.
