Rubber O Rings


Rubber O Rings

An O - Ring is a circular band with circular cross section to arrest leakages between two faces or over shaft and hole. They are designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

O–Rings selection is based on chemical compatibility, service temperature, sealing pressure, lubrication requirements and working atmosphere. Successful o-ring joint design requires a rigid mechanical mounting that applies a predictable deformation to the o-ring.    

This introduces a calculated mechanical stress at the o-ring contacting surfaces. As long as the pressure of the fluid being contained does not exceed the contact stress of the o-ring, leaking cannot occur. The seal is designed to have a point contact between the o-ring and sealing faces. This allows a high local stress, able to contain high pressure, without exceeding the yield stress of the o-ring body.

The flexible nature of o-ring accommodates imperfections in the mounting parts. Mostly these O Rings are used to seal hydraulic, pneumatic and wherever sealing is required. We manufacture O-rings, seals and associated components from a wide range of materials, with the shortest lead-times in India.    

When mismatching the sealing line and parting line, the sealing performance is improved due to the flash marks. Because there is a mechanical removal of flash is taken place in the sealing line.

The offset parting o-rings is widely used in critical applications. These o-rings are costlier than regular O-rings, because of their construction.

Our continual investment and development of product, personnel and customer satisfaction ensures we remain unrivalled in our field for quality and service.

O-Rings are also manufactured from over 15 polymers including:  Nitrile / Buna-N (NBR), Fluorocarbon (Viton®, Fluorocarbon (FKM), Silicone (VMQ), Fluorosilicone (FVMQ), Polyurethane (AU/EU), Natural Rubber (NR), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (HNBR), Styrene Butadiene Rubber (SBR), Chloroprene (Neoprene®), etc.
