This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to many acids, chlorinated solvents, and aggressive chemicals. Viton® (FKM) is known for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where low-molecular-weight organic acids or ketones and esters are present.

It sees regular use in automotive fuel systems, aerospace, and semiconductor equipment.
