FS Seals

Ideal for sealing large clearances, particularly those on surface wellhead-to-casing assemblies, the FS Seal design supports reduction in installation time, correct placement in the housing and simple installation.

High-performance FS Seals can retain sealing integrity under severe operating conditions, including:

  • Stab-in Operations
  • Wide Ranges of Temperature and Pressure
  • Chemically Aggressive and Highly Abrasive Media

Freudenberg Flow Technologies performs in-house product verification testing and analysis for our designed solutions and for proprietary customer projects at our Materials Development & Product Testing Lab. We offer a complete line of FS Seals design for API standard casing sizes ranging from 2 7/8” to 30” diameter
