In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

It resists engine and transmission fluids, many acids, and chlorinated solvents. Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or amines call for a different compound.

Common environments for this compound include aerospace, chemical processing, and automotive fuel systems.
