Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Applications involving aromatic hydrocarbons or petroleum oils and fuels call for a different compound.
Typical settings include potable water applications, HVAC and refrigeration, and outdoor equipment.
Order part number E80PC429, sold individually. Nominal inside diameter is listed as 5 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
