Description
KESARIA RUBBER INDUSTRIES is one of the largest manufacturers and exporters of Rubber O-rings in 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, Silicone, 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 the 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.
