API Heavy Duty Rotating Multi-Spring Single Cartridge Seal

The Flexaseal Style 59A is designed specifically to conform to API 682 Category 2 Applications for Midstream and Downstream Oil and Gas Applications. Standard design features include:

  • Oversized Monolithic Seal Faces for superior heat dissipation and durability.

  • Circumferential Flush System to evenly distribute cooling flush flow around the seal faces.

  • Convertible Outboard Bushing for fixed, floating and segmented designs to allow for all types of secondary leakage capture.

  • Tang Drive System for reliable face torque transfer and reduced O-Ring hang up.

  • Heavy Duty Springs to mitigate process debris clogging and reduce spring quantity.

The 59A is also available with contacting and noncontacting secondary sealing. The Flexaseal FC seal (Available as 59A/FC) provides decades of proven operational reliability as a contacting secondary seal. The Flexaseal FGSA (Available as 59A/FGSA) is our newest lift-off design for API applications that require a noncontacting secondary seal.
