In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to aggressive chemicals, engine and transmission fluids, and petroleum oils and fuels.

The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or amines are present.

Maintenance and OEM teams specify it across semiconductor equipment, oil and gas, and high-temperature process equipment.
