O-rings are one of the most common seals used in machine design because they are easy to make, reliable, and have simple mounting requirements. O-rings are measured by the inside diameter and cross section.
Backup rings are used when there is a possibility of gap extrusion. Backup rings are placed behind traditional O-rings to prevent the O-ring from extruding between the extrusion gap in the housing. Backup rings are made in solid or scarf cut.
Spring Energized Seals
Spring energized seals work well in applications with high speeds, under a wide range of temperatures, and with various media. A spring is used to energize the jacket of the seal to provide a constant load to the seal lip. The spring can be cantilever, canticoil, or helical wound. The spring type and spring load are both determined based on the application.
A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally designed to prevent leakage from or into the joined objects under compression. Gaskets fill irregularities on "less-than-perfect" mating surfaces on machine parts.
When a standard seal won’t fit your specific application, Wyatt Seal can help. Let our experienced team design or fit a custom shape and/or sized seal for your application.
