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. High flexibility due to extended selection of materials; Insensitive to low solids contents; Short Installation length possible (G16); Economical balanced seal; Seat cooling for hot water applications available (G115) and No damage of the shaft by set screws. EagleBurgmann is your best choice.
