Greene Tweed’s Chemraz ® 615 exhibits outstanding high temperature properties, with a temperature range from 0°F to 615°F (-18°C to 324°C). Chemraz ® 615’s chemical resistance and low compression set characteristics combine to out perform tin-cured FFKMs.

Chemraz ® 615 shows lower compression set at high temperatures and a higher retained sealing force than other available FFKMs.
Because Chemraz ® 615 allows for the use of higher process operating temperatures, it is ideal for a range of markets, from chemical process to petroleum refining. This superior FFKM performs well in a variety of fluids, such as inorganic and organic chemicals, acids, reagents, heat transfer fluids, and hydrocarbons.

Chemraz ® 615 is available in standard o-rings and custom shapes for a range of equipment, from pumps and valves to agitators and mixers, from mechanical seals and process control instruments to heat exchangers and diagnostic equipment.
