Plastic Sealing Solutions

Designed for Your Application

At North Coast Seal, we support OEMs and industrial manufacturers with precision plastic sealing solutions designed for environments where dimensional stability, chemical resistance, or low friction are critical. Plastic seals are often selected when rubber materials may degrade due to temperature, media exposure, or wear, or when metal solutions introduce unnecessary cost or complexity.

From PTFE-based components to high-performance engineered plastics, our team works closely with customers to evaluate application conditions and identify plastic materials that deliver consistent sealing performance over long service cycles.

Plastic Material Selection Considerations

Plastic sealing materials offer a wide performance range, making material selection especially important. While many plastics share similar base properties, differences in temperature capability, chemical resistance, and machinability can significantly affect seal performance.

Key considerations include:

  • Operating temperature range and thermal expansion
  • Exposure to aggressive chemicals, solvents, or cleaning agents
  • Static vs. dynamic sealing requirements
  • Wear resistance and coefficient of friction
  • Dimensional stability and tolerance requirements
  • Regulatory or industry-specific standards

North Coast Seal helps customers evaluate these conditions early to reduce premature wear, deformation, or seal failure in plastic-based components.
