Static O-Rings
Static O-rings are used in applications where there is no relative movement between sealing surfaces. They are intended to resist pressures, to not leak, and to provide vacuum integrity by either axial or radial compression sealing.
Rubber O-rings Manufacturers in India
Rubber and silicone O-rings are round rubber seals that sit inside a groove and are compressed between two parts to prevent the leakage of liquids or gases. The choice of right rubber O-ring is based on the fluid or chemical to be sealed, the operating temperature, pressure, lubrication and working conditions. They can be employed in stationary and moving applications such as reciprocating and rotating parts. Modern Rubber & Plastic Products is a rubber O-ring manufacturer in India, who is providing O-rings in various standard and custom sizes as per your drawing, sample and specifications for automotive, hydraulic, pneumatic, plumbing and all other industrial applications.

Rubber O-ring Material Selection Guide
Choosing the right elastomer is the single most important decision in O-ring performance — the wrong compound swells, hardens or fails; the right one seals for years. Match material to your operating conditions, then confirm the grade with our team.
