O ring, also known as packing or toric joint, is a kind of ring-shaped mechanical washer; it is an elastic body ring with circular cross-section, which is designed to be fixed in the groove, compress when assembling two or more parts, and form a seal at the interface. EagleBurgmann products deliver safe, reliable sealing performance in any application including oil pumping and cracking, gas compression, process gas containment, phase separation or synthesis of chemical substances, pipeline sealing, dairy product filling or compensation of temperature expansion in flue gas systems.
