Rubber Gasket Types and Sealing Applications

In the world of industrial sealing, Rubber Gasket products are critical for ensuring leak-proof connections, resisting environmental factors, and maintaining system integrity across various applications. This article provides a detailed overview of the primary types of Rubber Gasket materials, their key parameters, and their specific industrial uses, with a focus on the high-quality products manufactured by Hansheng Electrical. We will explore technical specifications through structured lists and comparison tables to help you select the ideal sealing solution for your needs.

Understanding Rubber Gaskets: Materials and Properties

Rubber Gasket materials are chosen based on their compatibility with operating conditions such as temperature, pressure, and media. Below are the most common types along with their characteristics:

1. Nitrile Rubber (NBR) Gaskets

   • Excellent resistance to oils, fuels, and solvents

   • Operating Temperature: -30°C to +120°C

   • Good abrasion resistance and mechanical properties

2. Silicone Rubber Gaskets

   • Superior flexibility and high-temperature resistance

   • Operating Temperature: -60°C to +230°C

   • Suitable for food and medical applications due to non-toxicity

3. EPDM (Ethylene Propylene Diene Monomer) Gaskets

   • Outstanding weather, ozone, and UV resistance

   • Operating Temperature: -50°C to +150°C

   • Ideal for outdoor and automotive applications

4. Neoprene Rubber Gaskets

   • Good resistance to oils, chemicals, and flames

   • Operating Temperature: -40°C to +100°C

   • Commonly used in refrigeration and HVAC systems

5. Fluoroelastomer (FKM/Viton) Gaskets

   • Exceptional resistance to high temperatures and aggressive chemicals

   • Operating Temperature: -20°C to +200°C

   • Preferred in aerospace, chemical processing, and oil industries
