Neoprene O-Rings

Neoprene is a balanced general-purpose elastomer used where moderate weather resistance, moderate oil resistance, and dependable basic mechanical properties are needed.

Typical temperature rangeAbout -40°C to +100°C typical.
Other namesNeoprene, CR, Chloroprene
Hardness optionsCommon hardness options may include 50, 60, 70, 80, and 90 Shore A.
Compliance optionsDepending on compound, Neoprene may be available with general industrial declarations and other application-specific grades.

Best used for

  • Balanced general industrial use
  • Outdoor applications with moderate weather exposure
  • Moderate oil and grease exposure
  • Refrigeration-related service in suitable grades

Key advantages

  • Useful balance of weather resistance and moderate oil resistance
  • Practical for many general industrial services
  • Good ozone resistance
  • Good aging resistance

Performs well in

  • Moderate exposure to oils and greases
  • Ozone and outdoor exposure
  • Weathering
  • Many general industrial environments
  • Some refrigerants depending on grade

Use with caution or avoid

  • Strong fuels
  • Aggressive solvents
  • Strong acids and alkalis unless validated
  • Very high-temperature service
  • Applications clearly better suited to a specialty elastomer

Typical applications

  • General industrial gaskets and seals
  • Outdoor sealing
  • Refrigeration systems in suitable compounds
  • Cable and enclosure sealing
  • Automotive and machinery sealing in moderate service

Common industries

  • General manufacturing
  • Refrigeration and HVAC
  • Electrical enclosures
  • Automotive support applications
  • Industrial maintenance
  • Construction and outdoor equipment

When to choose Neoprene

Choose Neoprene when the application needs a practical middle ground rather than one extreme property.

When not to choose Neoprene: Avoid or review carefully when your application involves strong petroleum oils and fuels, hot water and steam, high temperatures and aggressive chemicals, or extreme chemical service.

Selection guide

This is a practical selection guide. Final material choice should always be checked against actual fluid, temperature, pressure, movement, environment, and any approval requirement for the exact compound.
