Static seals are designed to prevent fluid leakage between two components that remain stationary. In such applications, there is no movement between the seal and the mating surfaces.

O-rings and X-rings are the most common types. Depending on the material, they can perform well under extreme temperatures, high pressure or exposure to aggressive chemicals.

Types of static seals

  • Flat seals (washer and shim types)

  • Circular seals (O, OX, OZ, OP)

  • Lip seals (U, VT)

  • Stuffing box seals

  • Sealing pastes

Static sealing rings are a versatile solution used in various applications such as:

  • gas systems

  • hydraulic systems

  • pneumatic installations
