The FORD METER BOX csun-3 is a union nut designed for use with 3/4 inch water meter setters. It provides the threaded connection that secures the union joint between the setter body and the meter interface, maintaining a leak-free seal under normal service line pressure. This fitting is a standard hardware component in water meter installation and replacement work, typically handled by licensed plumbers or water utility service technicians.
The csun-3 is used in residential and light commercial water service applications where 3/4 inch meter setters are installed. It is suited for meter pit or vault installations where the setter assembly requires a union nut to complete or re-establish the meter connection. Utility contractors and plumbing professionals will encounter this fitting during meter change-outs and setter maintenance.
Designed as an OEM-style replacement union nut for 3/4 inch water meter setter assemblies.
Installation is typically performed by a licensed plumber or water utility technician. Shut off the water service supply and relieve line pressure before removing or installing the union nut. Hand-tighten the nut first to ensure threads are properly engaged before applying a wrench to avoid cross-threading. Follow applicable local plumbing codes and utility specifications for meter setter connections.
