How to select rubber compound used in O-Rings

Common applications for each rubber compound used in O-rings:

 
1. Nitrile Rubber (NBR): o Applications: Automotive fuel systems, hydraulic systems, oil seals, and general-purpose sealing in industrial machinery.
2. Fluorocarbon Rubber (FKM): o Applications: Aerospace components, chemical processing equipment, oil and gas industry, and high-temperature applications in engines.
3. Silicone Rubber: o Applications: Food processing equipment, medical devices, automotive applications, and environments with extreme temperatures (both high and low).
4. EPDM (Ethylene Propylene Diene Monomer): o Applications: Weather seals for windows and doors, automotive cooling systems, roofing membranes, and outdoor equipment.
5. Neoprene: o Applications: Gaskets and seals in refrigeration systems, electrical insulation, automotive parts, and wetsuits.
6. SBR (Styrene-Butadiene Rubber): o Applications: Tires, conveyor belts, and various industrial applications requiring abrasion resistance but less chemical resistance.
7. Polyurethane: o Applications: Hydraulic seals, high-pressure applications, automotive and industrial components that require high wear resistance. Each compound's properties make them ideal for specific applications, helping to ensure reliability and longevity in their respective environments.
