O Rings

O Rings

O-RING is 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.

KESARIA RUBBER is one of the largest manufacturers and exporters of Rubber. O-rings in Gurugram, India. We offer our esteemed customers a wide range of elastomeric materials for both specials and standard applications which allow the O-Ring to seal basically all liquid and gaseous media. We specialize in the manufacturing of Rubber O-Rings ranging from 3 mm to 500 mm. We manufacture O-rings in various sizes and colors from various types of rubber like FKM or Viton, Silicon, EPDM, NBR, Neoprene, 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. When custom o-rings are required, the width or Thickness, Insider Diameter, and Outside Diameter are important to consider.
