What Are the Key Material Properties of Natural EPDM SBR Rubber Gaskets?

Understanding the material composition of our Natural EPDM SBR Rubber Gaskets is essential for selecting the right product for water and chemical systems. Our gaskets are designed to offer superior resistance to chemicals, ozone, and high temperatures, ensuring durability in demanding environments.


  • EPDM Content: Provides excellent resistance to water, steam, and alkaline substances, making it ideal for plumbing, HVAC, and industrial water systems.
  • SBR Content: Enhances mechanical strength and elasticity, allowing the gasket to maintain a tight seal under pressure variations.
  • Temperature Resistance: Suitable for continuous operation between -40°C and 120°C, with peak performance up to 150°C.
  • Chemical Resistance: Resistant to acids, alkalis, and oxidizing agents commonly found in water and chemical pipelines.
  • Compression Set: Low compression set ensures the gasket returns to its original shape after repeated load cycles, maintaining long-term sealing efficiency.


Property Specification Benefit
Hardness (Shore A) 65±5 Optimal balance of flexibility and rigidity for sealing
Tensile Strength >12 MPa High resistance to stretching and tearing
Elongation at Break >350% Ensures adaptability to flange and pipe surface irregularities
Temperature Range -40°C to 120°C Maintains performance under extreme conditions
Chemical Resistance Acids, Alkalis, Water, Steam Prevents corrosion and material degradation


Our factory carefully monitors the quality of every Natural EPDM SBR Rubber Gasket to guarantee consistent material properties. This ensures that our products perform reliably in both domestic and industrial systems.

  • Torque Specifications: Apply bolts uniformly in a crisscross pattern according to recommended torque values.
  • Avoid Over-Compression: Excessive pressure can deform the gasket and reduce its sealing capability.
  • Regular Inspection: Check for signs of wear, compression set, or chemical attack periodically.
  • Replacement Schedule: Replace gaskets proactively based on operational conditions rather than waiting for failure.


By following these procedures, our clients maximize the lifespan and reliability of our Natural EPDM SBR Rubber Gaskets.


What Maintenance Practices Ensure Long-Term Reliability?

Maintenance is essential for sustaining the performance of Natural EPDM SBR Rubber Gaskets. Our factory recommends systematic approaches that prevent premature wear and maintain optimal sealing performance.


  • Routine Inspections: Examine gaskets for cracks, deformation, or surface wear at regular intervals.
  • Cleaning: Use mild detergents or water to remove deposits without damaging the material.
  • Lubrication: Apply approved lubricants where necessary to facilitate installation or reduce friction.
  • Monitoring Operating Conditions: Ensure that temperature and chemical exposure remain within specified limits.
  • Prompt Replacement: Replace gaskets showing early signs of degradation to prevent system leaks.


Implementing these maintenance practices ensures our gaskets provide reliable performance throughout their service life, safeguarding system integrity and efficiency.
