PEEK Spring Loaded Seals

Spring Energized Seal Factory

FLUIDMEC Spring Energized Seals combine the chemical resistance of PTFE (or other high-performance polymers) with the resilient force of precisely engineered metal springs. This innovative design creates a sealing system that maintains consistent sealing force even under extreme temperature variations, pressure fluctuations, and exposure to aggressive chemicals.

  • Extreme Temperature Range: Functional from -200°C to +260°C, outperforming conventional rubber seals
  • Chemical Resistance: Inert to most chemicals, acids, and solvents thanks to PTFE jacket materials
  • Low Friction: Self-lubricating properties reduce friction and wear, extending equipment life
  • High Pressure Capability: Engineered to withstand pressures up to 35 MPa (5000 psi)
  • Excellent Compression Set Resistance: Maintains sealing force over extended periods
  • Long Service Life: Superior durability compared to conventional seals in harsh environments
  • Custom Design Capabilities: Tailored solutions for specific application requirements

What are the main advantages of spring energized seals over conventional elastomeric seals?

Spring energized seals offer several key advantages over conventional elastomeric seals:

  • Significantly wider temperature range (-200°C to +260°C vs typical -40°C to +150°C for elastomers)
  • Superior chemical resistance, particularly to aggressive media
  • Lower friction and improved wear resistance
  • Better retention of sealing force over time (less compression set)
  • Extended service life in harsh operating conditions
  • Ability to seal under both high pressure and vacuum conditions

To ensure we design the optimal seal for your application, please provide:

  • Seal dimensions or the dimensions of the hardware where the seal will be installed
  • Operating temperature range
  • Pressure conditions (maximum pressure, vacuum requirements)
  • Media being sealed (chemicals, gases, etc.)
  • Application type (static, dynamic, rotary)
  • Surface speed for dynamic applications
  • Hardware materials and surface finishes
  • Required service life or duty cycle information
  • Any special requirements (FDA compliance, low friction, etc.)

Our engineering team will review this information and recommend the optimal seal design and materials for your specific application.

What are the installation guidelines for spring energized seals?

Proper installation is critical for optimal performance of spring energized seals. Key guidelines include:

  • Ensure all hardware edges are chamfered and burr-free
  • Use appropriate installation tools to prevent damage to the PTFE jacket
  • Apply light lubrication compatible with your system media
  • Verify correct orientation of the seal (spring side typically toward pressure)
  • Avoid over-compression during assembly
  • Follow recommended gland design specifications
