Product Specification

-

This material stands up to ozone and weathering, sunlight and salt spray, and mild acids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in chlorinated solvents or ketones.

You will find this material specified across HVAC and refrigeration, general industrial, and transit and rail.
