O-Ring Characteristics Are Used Method

O-Ring characteristics introduction

O-Rings are circular rubber seals with a round cross-section, widely used for static and dynamic sealing applications in various industries including automotive, hydraulics, pneumatics, food processing, and medical devices.


🔍 Key Features of O-Rings

  • Simple structure – Easy to install and replace

  • High sealing performance – Suitable for both static and dynamic applications

  • Cost-effective – Low production cost, ideal for mass production

  • Versatile materials – Can resist oil, chemicals, steam, water, or extreme temperatures

  • Standardized sizes – Available in AS568, METRIC, DIN, JIS, and more


🛠️ Installation Guidelines

  1. Choose the correct size – Match inner diameter (ID) and cross-section (CS) to your groove

  2. Check material compatibility – Match the rubber type with the fluid or gas

  3. Avoid twisting or stretching – Use lubricant to ensure smooth installation

  4. Clean the surface – Remove dust or burrs from the housing and O-Ring

  5. Avoid damage – Prevent cuts or scratches during installation
