O RING MECHANICAL SEALS
O-rings are one of the most frequently used products in sealing applications, relatively inexpensive and reliable. O-rings come in many styles and shapes. The material required depends on temperature, pressure, chemical, and other environmental factors. Materials such as EPDM, Nitrile, Buna-N, Viton, FFKM are the most common materials that we supply. Applications range from garden hose couplings to critical aerospace or chemical plant duties.
Types of O Ring Mechanical Sealfor Sale
We supply all standard types of materials in a range of Shore Hardnesses and colours. In addition to standard imperial and metric sizes, Sealcon also supply a wide variety of non-standard sizes. Please feel free to inquire us if you need any O-rings. Materials include; Nitrile, Silicone, EPDM, FKM, Viton, FFKM, and HNBR.
Application of O Ring Mechanical Seals
O-ring is mainly used in the fluid static application (For example, water, oil, air, chemicals solvent, chemicals, etc.).
The temperature range is from -60 ℃ up to 220 ℃.
The pressure in the static application should be less than 20MPa, which varies with different materials.
Sometimes O-ring is used in the dynamic application with the pressure less than 5MPa and also used in semiconductor vacuum seal.

Perfluorocarbon (FFKM)
FFKM offers excellent resistance to chemicals and extreme temperatures. Special compounds can operate beyond 300°C. FFKM is resistant to most chemicals including inorganic acids, alkalines, ketones, esters, alcohols, fuels, and hot water. It is ideal for applications in aggressive chemical environments.
Our Standard FFKM compound has outstanding heat resistance with service temperatures of -10°C to 310°C. Sealcon can offer direct equivalents to Kalrez, Simrez, Perlast, Chemraz, grades.
Aflas
Aflas is a specialty, non-conventional fluoroelastomer. A cousin of Viton, it offers higher heat resistance and performs well in high concentrations of acids, oxidants, and alkalis. Aflas is usually somewhat more expensive than Viton.
Kalrez
Kalrez is usually the most expensive elastomer option available. With specialty compounds available for use with nearly any chemical, and the ability to withstand temperatures up to 600 °F, Kalrez is an amazing elastomer. O-rings often cost hundreds of dollars each, so Kalrez is only used where absolutely necessary.
Specialty Elastomers
There are a variety of specialty elastomers on the market, most of which compete with one of the above materials. Sometimes these are specified by a seal or pump OEM, and Infinity Pump can source these materials for you.
Hangzhou Sealcon Fluid Machinery Co., Ltdis a professionalchina o ring supplier, we provide china rubber seal, mechanical shaft seals springs, seal ring mechanical, ring mechanical, pumping ring in mechanical seal, seal ring material, mechanical seal pumping ringand etc. For more information, please feel free to contact us!
