The design of high pressure rotary seals considers several key factors, including the type of fluid being sealed, operating temperature, pressure, and the speed of rotation. Typically, they are made from advanced materials like elastomers, PTFE (polytetrafluoroethylene), and specialty composites that can endure extreme conditions. The seal's design often incorporates a lip that makes contact with the rotating shaft, creating a barrier against the pressure.

Geographic factors also impact oil seal pricing. Production costs can vary by region due to labor costs, access to raw materials, and regulatory requirements. For example, seals manufactured in countries with lower labor costs may be more competitively priced. However, shipping costs and tariffs can offset these savings, especially in markets that rely on imports for their oil seals.
