An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to aggressive oxidizers, nearly all process chemicals, and strong acids and solvents. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C).
Common environments for this compound include aggressive-media valves and pumps, pharmaceutical manufacturing, and semiconductor equipment.
