Designing Axial Static O-ring Grooves to "Industry Standards"

Thomas Larson

This Covers 2/3 of everything I know about designing O-ring seals. I frequently used these while designing production tools. Most the design is based on the standards that are put forth by SAE. Personally, I be going over the reiteration by Parker since it's what I learned. Other references include the Apple Rubble Product and Trelleborg for their proprietary O-ring Gland Calculators, and the help they gave me in building my own. Links to their websites are found in Section 5. All design in this lesson is for "Static Axial Design under normal conditions”. Disclaimer: while I have completed a BS in Mechanical Engineering and have passed the FE, I am not a PE. While these calculations are standard, published, and I personally have used these practices to design multiple high-pressure tools, I cannot guarantee that they a perfect. If you are in doubt, in a hazardous environment, or using in an application that could cause harm to life, I would suggest double checking with other sources (engineering) and/or extensive testing. Also, my experience is in Oil and gas, in the continental USA. You may notice my practices being bias to API standards and in English Units, I suggest you take all I say with a grain of salt. Lesson Plan: Step 1: Background and Definitions Step 2: Finding a Published O-ring Gland and incorporating it into a design. Step 3: Designing Custom Groove using the Standards Step 4: Other Design Recommendations and Drafting Example Step 5: References and Useful links A copy of the files can be found at: https://grabcad.com/library/how-to-design-an-o-ring-gland-to-industry-standards-parts-and-photos-1
