Metric O-Rings

O-Rings, also known as packing seals, are mechanical gaskets created in the shape of an O, which can be placed into a groove and compressed between two or more parts. Often used in hydraulic cylinders and pump shafts, they are the most common seals used in machinery as they are simple, effective and cost-efficient.

With a high resilience to pressure and a wide variety of sizes available, O-rings are the top choice for most hobbyists on their mechanical projects.
