O-Rings are used to seal mechanical parts against fluid movement (air or liquid). O-Rings perform their sealing action by deforming to take the shape of their cavity, after being oversized to guarantee a predetermined interference fit. O-Rings are inserted into cavities defined as glands, and are typically used in one of two seal designs - axial or radial. An O-ring sealing system is often one of the first sealing systems considered when a fluid closure is designed because it has several advantages including simplicity, low cost, ease of installation, ease of maintenance, no adjustment required and no critical torque in clamping.
