Description
The RIDGID 31487 Repair Coupling is a precision-engineered splicing component designed to restore continuity in 5/8" drain-cleaning cables used with RIDGID drum/auger machines.

- Easy installation in the field — With minimal tools, the coupling can be installed onsite, reducing downtime and repair effort.
- OEM assurance — As a genuine RIDGID replacement part, you retain system integrity and compatibility with your existing RIDGID setups.
- Lightweight & compact — Does not add significant bulk to the cable — ideal for tight spaces and quick repairs.
Suggested Use Cases
- Repairing a broken 5/8" cable on a RIDGID drum machine without needing full cable replacement
