O Ring
Expert Summary
O-rings are used in a wide variety of applications where sealing is required. In mechanical assemblies, they can be found in hydraulic and pneumatic systems, automotive engines, and aerospace components. Users often face issues with leaks due to pressure, temperature fluctuations, or incompatible materials. This O-ring provides a reliable seal, preventing fluid or gas loss and ensuring the efficient operation of the machinery.
Solved problems
- Prevents fluid and gas leaks
- Ensures tight seals under pressure
- Resists chemical degradation
- Maintains seal integrity in varying temperatures
Common failure scenarios
- Brittleness at low temperatures
- Swelling in contact with certain chemicals
- Loss of elasticity over time
- Extrusion under high pressure

FAQ
Q: What materials are commonly used for O-rings?
A: O-rings are made from a variety of elastomeric materials, including nitrile (Buna-N), EPDM, silicone, Viton (FKM), and PTFE, chosen based on the application's temperature, chemical exposure, and pressure requirements. Stainless steel is used for more robust applications where metal seals are preferred.
Q: How do I determine the correct O-ring size?
A: Correct O-ring sizing depends on the groove dimensions (width and depth) and the shaft or housing diameter. Standard O-ring sizing charts and calculators are available to help match the O-ring dimensions to the groove and gland specifications for a proper seal.
Q: What is the temperature range for stainless steel O-rings?
A: Stainless steel O-rings can generally withstand a wider temperature range than many rubber O-rings, often performing effectively from cryogenic temperatures up to 800°F (427°C) or higher, depending on the specific alloy and application. However, their sealing capability relies on the compression provided by the gland design.
