O-Ring Materials We Offer

Every application demands the right elastomer. We provide carefully compounded materials tailored for temperature, chemical, and environmental resistance.

  • EPDM (Ethylene Propylene Diene Monomer) – Excellent weather resistance & UV stability; ideal for outdoor sealing and water applications.
  • FKM (Fluoroelastomer / Viton®) – Superior chemical resistance, high-temperature performance (up to 250°C), and excellent fuel compatibility.
  • FFKM (Perfluoroelastomer / Kalrez®-type) – Premium elastomer with near-universal chemical resistance and continuous service up to +320°C. Perfect for semiconductor, pharmaceutical, aerospace, and chemical processing.
  • Silicone – Excellent high & low temperature resistance (-60°C to +200°C), electrical insulation properties, and food-grade variants available.
  • Nitrile (NBR) – Good oil & fuel resistance; widely used in automotive & industrial sealing applications.
  • Neoprene (CR) – Strong ozone, weather & chemical resistance; ideal for marine and construction applications.

O-Ring FAQs

Size Selection

Q1. How do I determine the correct O-ring size?
O-rings are measured by inner diameter (ID) and cross-section (CS). Refer to standards such as AS568, BS, or JIS, or request a custom size.

Q2. Do O-ring sizes differ by country?
Yes. Different standards use different numbering systems. We supply all international sizes and custom-molded options.

Q3. What if I need a non-standard size?
We offer custom-molded O-rings designed to match your groove dimensions and performance needs.

Material Selection

Q4. How do I choose the right O-ring material?
Consider:

  • Temperature range
  • Chemical compatibility
  • Static vs. dynamic application
  • Regulatory compliance (FDA, USP, aerospace)
  • Cost-performance balance

Q5. Which materials are most common?

  • NBR – Oil & fuel resistance
  • EPDM – Steam, water, weather sealing
  • FKM (Viton®) – Heat & chemical resistance up to 250°C
  • FFKM – Extreme resistance up to 320°C
  • Silicone – High/low temperature, food-grade options
  • Neoprene – Ozone & weather resistance

Q6. When should I choose FFKM instead of FKM?
Choose FFKM for extreme chemicals, purity requirements, or >250°C conditions. Ideal for semiconductor, pharma, aerospace, and critical chemical processes.

Applications

Q7. Which industries use O-rings the most?
O-rings are essential in Oil & Gas, Food & Beverage, Pharma, Medical, Automotive, Aerospace, and Electronics industries.

Q8. Can O-rings be used in both static and dynamic applications?
Yes.

  • Static O-rings seal between fixed surfaces.
  • Dynamic O-rings are used in moving parts (pistons, shafts) and require precise material selection.

Q9. Are O-rings suitable for food and pharma?
Yes, with FDA, USP Class VI, and 3A Sanitary compliant materials like Silicone, EPDM, and FFKM.

Q10. How long do O-rings last?
With the correct material and environment, O-rings can last several years without failure.
