Unlike standard molded O-rings, FKM O Ring Cord allows users to cut and vulcanize to any required size, providing maximum flexibility for large-diameter seals, non-standard grooves, maintenance repairs, and emergency replacements.

FKM O Ring Cord is widely used in industries where reliability, chemical stability, and long service life are critical.

FKM is a premium elastomer known for its outstanding performance under extreme operating conditions. Compared with conventional rubber materials, FKM offers superior thermal and chemical stability.

Key material properties include:

Continuous operating temperature up to +200°C

Excellent resistance to oils, fuels, hydraulic fluids, lubricants

Strong resistance to chemicals, acids, solvents, and hydrocarbons

Low compression set, ensuring long-term sealing performance

Good aging resistance and ozone resistance

These properties make FKM O Ring Cord especially suitable for applications where standard NBR or EPDM materials fail.
