KESARIA RUBBER INDUSTRIES stands as one of India’s leading manufacturers and exporters of Rubber O-Rings, with a production capacity of 550,000 units per day. We provide a diverse selection of elastomeric materials suitable for both special and standard applications, enabling our O-Rings to seal a wide range of liquids and gases. Our expertise includes producing O-Rings from 3 mm to 500 mm in various sizes and colors, using materials such as FKM (Viton), Silicone, EPDM, NBR, Neoprene, SBR, and Natural Rubber. The hardness of our O-Rings ranges from 30 to 95 Shore A Durometer. For custom O-Rings, precision in width, thickness, inner diameter, and outer diameter is crucial, and our engineers are available to ensure the specifications meet your needs.
O-Rings
Rubber O-Rings are a loop of elastomer with a round cross-section intended to be seated in a groove and squeezed together during assembling between two or more parts creating a seal at the interface to block the passage of liquids or gases. O-Rings selection is based on chemical compatibility, service temperature, sealing pressure, lubrication requirements, and working atmosphere. O-rings can form a static or dynamic seal. 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.
