Sigma GALCOUP3I-LF 3 Inch Galvanized Coupling

Product Description

The SIGMA GALCOUP3I-LF is a 3 inch galvanized IMI coupling designed for joining pipe sections in plumbing and mechanical systems. This lead-free fitting meets modern potable water and plumbing code requirements, making it suitable for installations where lead-free compliance is mandated. The galvanized steel construction provides corrosion resistance for long service life in wet and exposed environments. Licensed plumbers and pipefitters are the primary installers of this type of coupling in both new construction and retrofit work.

This coupling is suited for residential and light commercial plumbing, mechanical piping, and drainage applications where a 3 inch connection is required. The galvanized finish makes it appropriate for use in areas with moderate moisture exposure. It is commonly installed in supply piping, vent runs, and mechanical room piping configurations where a reliable, code-compliant coupling is needed.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC).
