1. The O-ring is an annular seal having an O-shaped cross section,
the size of which is determined by the inner diameter ID and the
wire diameter CS.
2. O-ring size calculation: outer diameter = inner diameter + 2 x
wire diameter (OD = ID + 2x CS).
3. The purpose of using O-ring seals is to prevent leakage and loss
of liquids or gases.
4. O-rings are the most commonly used type of seal because of their
simplicity, convenience, and small installation space. As long as
the groove design and material selection are correct, and the
operating conditions are within the temperature range of the rubber
material, the seal can have a long-term sealing effect in the
static or dynamic seal.
