An slurry pump O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

For slurry pumps, there are some O rings like Rubber Bearing sealing ring(code 089), Impeller O ring(code 217), Shaft O ring(code 109)
