Features & Benifits
Metal O-ring is a high-strength metallic tube designed to be used in harsh working conditions. It’s a sealing choice for high-pressure/high-temperature applications with little spring back. Metal O-rings may be utilized in high temperature (up to 750°C), cryogenic (down to -270°C), high pressure (up to 1500kgf/cm2), high vacuum (up to 1E-9 mmHg), and other extreme static sealing conditions due to their unique structure and composition.
