O-rings are mechanical sealing elements commonly used to ensure tightness between two surfaces in contact. They are composed of a torus-shaped (or donut-shaped) ring made from various materials such as rubber, silicone, Viton, EPDM or polyurethane.<\/p>\n
<\/p>\n
These seals are used in a variety of industrial applications, including hydraulic and pneumatic systems, chemical processing equipment, food production machinery, medical equipment, measuring instruments, engines, and transmissions.<\/p>\n
<\/p>\n
The materials used to manufacture O-rings are chosen based on the specific requirements of the application, such as temperature, pressure, chemicals, and wear resistance.[\/vc_column_text][vc_tta_accordion][vc_tta_section title=”Nitrile (NBR) is the most commonly used elastomer for sealing thanks to its:” tab_id=”NitrileNBR”][vc_column_text]![\"\"](\"http:\/\/maroc-joint.com\/wp-content\/uploads\/2023\/04\/nitrile-o-ring-300x165.jpg\")
