Product Detail

Key Features:

● Chemical Resistance: Outstanding resistance to nearly all chemicals, including acids, solvents, amines, and hydrocarbons—comparable to PTFE (Teflon).
● High Temperature Resistance: Can withstand continuous exposure to temperatures up to +327°C (620°F), depending on the compound.
● Low Outgassing: Ideal for cleanroom and vacuum applications (e.g., semiconductor manufacturing).
● Compression Set Resistance: Maintains excellent sealing over long periods, even under extreme conditions.

Applications:

● Semiconductor & Electronics Manufacturing
● Pharmaceutical & Biotech Equipment
● Aerospace & Aviation Systems
● Chemical Processing Plants
● Food & Beverage Sanitary Systems

Advantages:

- ● Maximum uptime in aggressive environments
- ● Long service life and fewer maintenance shutdowns
- ● High purity for sensitive processes
Our FFKM O-rings include KH Series, KR Series and KS Series as below sheet.

FFKM O-rings are a top choice where failure is not an option, and extreme performance is required—though they come at a higher cost compared to standard elastomers.
