The O-ring seal closely adheres to the sealing surface through elastic deformation, effectively preventing the leakage of liquids or gases. Suitable for high pressure (over 1000Bar), vacuum, or corrosive environments, they are widely used in hydraulic systems, chemical equipment, and aerospace.
Available in Nitrile (NBR), Fluororubber (FKM), Silicone (VMQ), EPDM, and PTFE. This diversity allows O-rings to meet requirements for various temperatures, pressures, and media across all industries.
Compact structure particularly suitable for narrow installation environments. Miniaturized design helps make equipment lightweight without sacrificing sealing performance, ideal for precision instruments and electronic devices.
