An Rubber 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.
Rubber 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 Rubber 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 Rubber o-ring accommodates imperfections in the mounting parts. Mostly these O Rings are used to seal hydraulic, pneumatic and wherever sealing is required. Prasee Rubber & Plastic Technology manufacture Rubber 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 said offset parting orings is widely used in critical applications. These Rubber o-rings are costlier than regular O'Rings, because of its construction.
Prasee Rubber & Plastic Technology can manufacture virtually any seal, in any material, while you wait, and can manufacture custom parts for all seal applications. Our continual investment and development of product, personnel and customer satisfaction ensures we remain unrivalled in our field for quality and service.
