Nov 01, 2018· One seal face is fixed and sealed statically using an O-ring or cup gasket. The other is spring-loaded and requires a semi-dynamic seal to accommodate some axial play, such as a dynamic O-ring in pusher-type mechanical face seals or elastomeric bellows in nonpusher ones.

Natural Rubber o-rings are stocked and cataloged by their AS568 number. This number references the Aerospace Standard 568 (AS 568) which was published by the SAE (Society of Automotive Engineers). Each o-ring is assigned a dash number which correlates directly to an exact o-ring size. You may view a complete chart of these o-ring sizes here.

elastomers, showing continuous dry-heat resistance to 500oF (260oC) with extended performance to 626oF for high temperature grades. They show excellent resistance to a majority of chemicals that attack other elastomers, and have good long-term high temperature compression set resistance. Applications are sealing systems in oil

About O-Ring. In designing an O-ring Seal, it is best to determine the O-ring compound first, as the selected compound may have significant influence on gland design parameters. Essentially, the application determines the rubber compound; The primary factor being the fluid to be sealed.

Good lubrication can improve and extend the performance life of valves, packings, seals and O-rings – but not all lubricants are compatible with the process stream, and improper lubrication can cause seizure or leaks. Selecting the right MOLYKOTE® Specialty Lubricant can enhance performance for better sealing and longer service life.

High-pressure resistance is a common requirement of industrial o-rings, along with reliable performance in high temperature and dynamic environments. For a high-pressure seal to work to optimal levels, o-ring design and manufacture again depends on choosing specific materials for better performance under specific conditions.

Technical Handbook O-rings Lower compression set values indicate improved remaining seal capacity. Compression set values generally increase with increased temperature and time. For O-rings the minimum squeeze should be about .007 inch. (0,175mm). The reason is that with a very light squeeze almost all elastomers quickly take compression set.
