O-Rings are endless, ring-shaped sealing elements with a circular cross-section that are manufactured from elastomer materials or PTFE. The designation of an O-ring is derived from the dimensions of its inner diameter and cord width in millimeters, along with the name of the material and its Shore A hardness (e.g. 90.00x3 FKM 70).
Dimensional tolerances in accordance with DIN ISO 3601-1, industry class B. Surface deviations in accordance with DIN ISO 3601-3, type feature N
O-Rings are one of the most common seals used in machine design because they are cheap and simple, reliable, and have simple assembling requirements. They are readily available in many different sizes with lubrication sometimes needed for fittings with non-static areas.
The O-Ring's application areas are found in numerous sectors, such as hydraulics, vehicle manufacturing, and vacuum applications, and in plant engineering and machine-building.
Changzhou Meridian offers many different high quality rubber O rings for all types of environments and sealing applications. The materials include, but are not limited to, NBR, HNBR/HSN, Viton/F
