Ductile Iron Construction
These backup flanges are manufactured from ductile iron, providing high tensile strength and toughness for demanding piping installations. Ductile iron offers improved impact resistance compared with traditional cast iron and is well suited for mechanical piping components requiring strength and durability.
Backup Flange Design
The backup flange configuration is designed to provide mechanical support and bolt alignment when used with compatible flange components. Precision-machined bolt holes help maintain proper alignment during assembly and support a secure flange connection.
Available Sizes
Available nominal pipe sizes include:
- 1/2"
- 3/4"
- 1"
- 1-1/4"
- 1-1/2"
- 2-1/2"

- 4"
Selection & Application Guidance
- Select the backup flange size to match the nominal pipe size and mating flange components.
- Verify bolt-hole alignment and compatibility with the mating flange before installation.
- Confirm that the selected gasket and hardware are appropriate for the piping system.
- Verify system pressure, temperature, and media requirements before installation.
- Gaskets, bolts, nuts, and other installation hardware are typically sold separately unless otherwise specified.
- Follow applicable piping standards and installation requirements when assembling the flange connection.
