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

The material holds up against many alcohols, water, and greases and lubricants. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or polar solvents.

You will find this material specified across hydraulic and pneumatic systems, general industrial maintenance, and construction equipment.
