What Is It?

Expansion rings are brass rings that are installed during the fire hose coupling attachment process. The ring is expanded inside the hose and coupling assembly to create a secure connection between the hose and fitting. These rings are commonly used in the manufacture, repair, and recoupling of fire hoses.

How Is It Used?

Expansion rings are installed using specialized expansion equipment during hose assembly or repair operations.

1. Insert the expansion ring into the hose end.
2. Position the coupling according to the manufacturer's assembly procedure.
3. Use expansion equipment to expand the ring inside the hose.
4. The ring compresses the hose against the coupling shank, creating a secure connection.
5. Verify proper installation before placing the hose into service.
