- Backup Rings These are used in conjunction with O-rings to provide additional support and help prevent extrusion, especially in high-pressure applications.

Rotary shaft seals are widely used across many industries, including automotive, aerospace, manufacturing, and consumer products. In the automotive sector, they can be found in engines, transmissions, and wheel hubs. Their primary role is to manage oil flow, thereby preventing leaks that could lead to system failures or costly repairs. Similarly, in industrial machines, these seals help maintain lubrication in bearing systems and pumps, ensuring a smooth operation.
