Mainly check the material, thickness, appearance quality, surface corrosion (rust) and aging of non-metallic parts in accessories.
Conclusion
made of a yieldable resilient material having flat sealing faces and comprising two ring portions connected together by an annular portion substantially v-shaped in cross-section which may yield or expand as the mounting requires.
Temperature - Just like pressure, the temperature that your oil seal will be operating in must be known so that you can choose one that can withstand the heat or cold. PTFE have the widest range of temperature, making them useful for machines who can see usage in extreme weather or elements.
Heat resistance
ERIKS
Broad chemical resistance, except against liquid alkaline metals and fluorine gas under pressure. Good sliding qualities, low wear and tear. Temperature range from -200 °C to +260°C. PTFE has hardness of approximately 95 °Shore and installing these O-rings in split grooves is recommended or alternatively the use slit or sheathed types due to the low elasticity.
If the gap is larger than 0.002 in. (0.05 mm) at any point, have the head or block checked and machined flat by a specialist.
One of the primary advantages of natural rubber gaskets is their excellent sealing properties. Due to their inherent elasticity and compression set resistance, natural rubber gaskets can effectively conform to irregular surfaces, creating a tight seal that prevents fluids or gases from leaking. This is especially important in industries such as automotive and aerospace, where even the smallest leak can lead to catastrophic consequences.
In conclusion, U-shaped silicone gaskets, white rubber gasket sheets, and waterproof rubber gaskets offer versatile and effective sealing solutions for a wide range of industrial and commercial applications. Understanding the advantages and applications of these gaskets is crucial for selecting the appropriate sealing components to ensure protection, reliability, and longevity in various systems and equipment.
