It remains the most cost-effective sealing element available for pressurized assemblies.
The material holds up against refrigerants and ammonia, mild acids, and sunlight and salt spray.

The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with aromatic hydrocarbons or chlorinated solvents.
It sees regular use in marine equipment, transit and rail, and weather sealing and enclosures.
