Silicone O-Rings vs. Rubber O-Rings: Key Differences

Discover the disparities between silicone and rubber O-rings to select the optimal sealing solution. Delve into their properties, applications, and advantages.

Material Composition:

• Silicone O-Rings: Crafted from silicone polymer, providing flexibility and temperature resistance (-60°C to 230°C).
• Rubber O-Rings: Comprised of diverse rubber compounds like NBR, EPDM, neoprene, or FKM, each with distinct properties.

Performance Characteristics:

• Silicone O-Rings: Flexible, low compression set, and excellent electrical insulation.
• Rubber O-Rings: Versatile, resistant to abrasion, tearing, and mechanical stress.

Applications:

• Silicone O-Rings: Perfect for food, pharmaceuticals, electronics, and extreme temperature environments.
• Rubber O-Rings: Widely utilized in hydraulic systems, automotive engines, and industrial machinery.

Opt for silicone for temperature extremes and specialized applications; choose rubber for versatility and durability in demanding conditions.
