The FORD METER BOX EC-1-NL is a 5/8-inch expansion wheel used in water meter service connections. Expansion wheels are a critical mechanical component in meter coupling assemblies, allowing controlled engagement between the meter and the service line. This part is sold as a single unit and is installed by licensed plumbers and water utility technicians during meter setting or replacement work. The 5/8-inch sizing corresponds to standard residential meter connection dimensions commonly found in municipal water service applications.
The EC-1-NL expansion wheel is suited for residential water service meter installations where a 5/8-inch coupling interface is required. It is typically used during new meter installations, meter exchanges, or coupling repairs on potable water service lines. Water utility contractors and licensed plumbers are the primary installers of this component.
Designed as an OEM-style replacement expansion wheel for 5/8-inch water meter coupling assemblies.
Installation should be performed by a licensed plumber or authorized water utility technician in accordance with local plumbing codes and utility requirements. Shut off the water service supply and depressurize the line before disassembling any meter coupling components. Inspect adjacent coupling parts for wear before installing the new expansion wheel. Follow the meter manufacturer's assembly guidance for proper seating and engagement.
