Rubber O-ring seals have been widely used in high-pressure hydrogen storage systems for preventing gas leak. The swelling and bubbling phenomenon of O-ring in high-pressure hydrogen environment is the main reason for its leak failure [35, 49, 50]. GB/T 42612 specifies that the O-ring materials shall have good hydrogen compatibility.
Wrapping, storage in airtight containers or other suitable means should be used for vulcanised rubber items. 5. Deformation. Where possible, rubber items should be stored in a relaxed position, free from tension or compression. Laying the item flat and avoiding suspension or crushing keeps it free from strain and minimises deformation. 6.
