O-RINGSare solid-rubber, doughnut shaped seals. When pressed between two mating surfaces, O-rings block the passage of liquids or gases. O-rings can form a static or dynamic seals. A static seal is where the O-ring does not move and is used simply for containing pressure or maintaining a vacuum. Dynamic seals can be reciprocating (like a piston and cylinder), or rotating (shaft rotating in a housing). Axial squeeze and radial squeeze are two methods for applying an O-ring. An axial squeeze is when the ring is compressed parallel to a line drawn through the centre or axis of the ring. In a radial squeeze the ring is compressed between the internal diameter (ID) and overall Diameter (OD).

O-rings are typically available in standard sizes as per industry standards. These include "AS568" standard sizes (001-475), British Standard Metric Sizes, JIS Standard Sizes, JASO Standard Sizes, AS871, and custom. When custom o-rings are required, the width or Thickness, Insider Diameter, and Outside Diameter are important to consider. Common materials of construction for o-rings includeAflas, VITON, SILICON, HYPALON, EPDM, TPR, NBR, NEOPRENE, PTFE, PU, SBR&NATURAL.The hardness rating on a Shore A scale for O-rings can be 30 95 Durometer. Exact specifications should be clarified by our engineers, as chemical and physical properties of an O-ring can differ based on manufacturing technique.

Rubberring for shafts requiring a dynamic seal (primary or back-up) in the axial direction. The body of V seals rotate with the shaft and holds itself in position by its elastic fit on the shaft. Sealing is produced by the contact between the lip and the counterface. Additionally, the V Series seal has good sealing action when the shaft is eccentric and/or there is some misalignment. Combined with radialshaft seals, these axial face seal designs provide excellent excluding characteristics against all types of liquids, greases, oils, dirt, snad and other foreign materials.V-Rings are available in both Buna N andViton.

Typical applications: Conveyor Rollers, Appliances, Motors, agriculture, wheel hubs, appliances, pumps and gear boxes.
