Rubber O-ring

A self-seal type rubber O-ring that is made by putting various rubber elastomers into a mold and machining both ends together into a circular shape.
In addition to a shaft seal (packing), it is also fitted into grooves and used as a gasket. It adapts well even with a small clamping load, and can seal against a vacuum pressure up to a high pressure of 25 MPa.
