Backing Rings

ABS backing rings provide the essential mechanical strength needed to form a secure flanged joint within an ABS pipework system. Manufactured from durable galvanised steel, these rings offer excellent corrosion resistance and reliable long-term performance in both industrial and commercial environments.

Available in a full range of imperial and metric sizes, our backing rings are drilled to suit the most common flange standards, including:

• BS EN 1092-1 PN10/16
• Tables D and E of BS 10:1962
• ASA/ANSI 150

This makes it easy to pair each ring with the correct ABS flange, gasket and bolt set for your installation.

Each galvanised backing ring is designed to match an imperial or metric ABS flange of the same nominal size. The ring is positioned on the plain-ended flange before the pipe is glued, allowing you to assemble a face-to-face flanged joint using:

• A suitable gasket
• The correct bolt set (number and size matched to the drilling)

This combination provides a strong, reliable, and leak-resistant connection, ideal where pipework may need to be dismantled for maintenance or inspection.

To complete your installation, make sure to add:

• ABS flanges
• Gaskets
• Bolt sets

These accessories ensure a fully compatible and properly sealed flanged joint.
