Product Identity

The Ridgid 37643 is a 5/8 inch by 100 foot drain cleaning cable built with an inner core steel construction. It is designed for professional plumbers and maintenance crews clearing blockages in 3 inch to 6 inch internal diameter lines.

Interface Limits

The cable connects to compatible Ridgid machines including models 750, 6200, and 7500 using a 5/8 inch male coupling. Maximum continuous run is 100 feet and the cable is rated only for the specified drain line capacity range.

Installation Notes

The included male coupling allows direct attachment to the listed machine models without additional adapters. Common issues occur when the cable is forced past its 100 foot maximum run or used in lines outside the 3 to 6 inch capacity, leading to kinking or coupling damage.

Questions about this item

Which Ridgid machine models work with the 37643 5/8 in. x 100 ft. inner-core cable?

The cable fits Ridgid K-750 (42007), K-6200 (93557) and K-7500 (60052) machines.

How does the 100 ft. length perform on a 3 in. to 6 in. drain line?

The 100 ft. run reaches deep blockages in 3 in. to 6 in. I.D. lines; the inner-core steel construction resists kinking while transmitting torque to the cutter.

What does the 5/8 in. connection size limit in practice?

The 5/8 in. male coupling only mates with matching 5/8 in. machine chucks and tool heads, so the cable cannot be used on smaller or larger drive systems.
