High-temperature FKM O-rings are specified for sealing applications involving heat, oils, fuels or chemical media. Compound selection should be based on the actual medium, continuous and peak temperature, pressure, sealing type and required documentation.
FKM is commonly considered for sealing systems exposed to heat, oils, fuels, and chemical media. Final material selection should be based on the actual medium, temperature range, pressure, seal movement, and required documentation.
Confirm continuous and peak temperatures together with the expected exposure duration.
Identify the exact liquid, gas, oil, fuel, or chemical that will contact the seal.
Specify whether the seal is used in a static joint, valve, reciprocating assembly, or other moving position.
Provide operating pressure, pressure cycling, dimensions, and groove details when available.
Final material and production details are confirmed against the drawing, service conditions, and project requirements.

These applications may require an elastomer selected around temperature, fluid exposure, pressure, and sealing duty rather than a general-purpose compound.
For sealing positions involving fuels, lubricants, and elevated operating temperatures where the selected grade is compatible.
For valve assemblies exposed to pressure, elevated temperature, oils, or chemical media.
For pumps, fittings, and process equipment after the specified medium has been reviewed against the compound.
For machinery and assemblies where heat, fluid exposure, and sealing conditions require a reviewed material specification.
Provide the key operating details with your drawing or size information so the material and sealing specification can be reviewed before quotation.
