Maintenance and OEM teams specify it across solar and roofing assemblies, water and steam systems, and outdoor equipment.
Order part number E80PC448, sold individually. Nominal inside diameter is listed as 9 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
