The MATCO-NORCA 289401 is a 1-inch water meter connector designed to provide a reliable, leak-free connection at residential and light commercial water meter installations. This fitting serves as the interface between the water meter and the supply line, maintaining flow integrity under normal municipal water service conditions. Licensed plumbers install this connector during new meter sets and meter replacement service calls. Its 1-inch size suits the most common residential service line diameter found in single-family and small multi-unit applications.
The 289401 is suited for use in residential potable water systems where a dependable meter connection is required at the point of service entry. It fits into standard meter setter configurations and is appropriate for use in both new construction and retrofit installations where the existing meter or connector is being replaced. Plumbing contractors and water utility service technicians are the primary installers of this fitting.
Designed as an OEM-style replacement connector for 1-inch residential and light commercial water meter installations.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC requirements. Shut off the main water supply and relieve line pressure before removing or installing any meter connector. Inspect mating threads and sealing surfaces for damage before making connections. Do not overtighten fittings, as this can damage threads or sealing surfaces on the meter body or service line.
