Black OEM Logo Packing Food O rings

What is an o-ring? An o-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section (from which the “O” in its name is derived). The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases. They 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. The size of o-ring is determined by the inner diameter ID and the wire diameter CS. O-ring size calculation: outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).
