Southland 511-403HN 1/2 Inch Galvanized Pipe Cap

Product Description

The SOUTHLAND 511-403HN is a 1/2 inch galvanized steel pipe cap designed to terminate the end of a threaded piping run. The hot-dip galvanization provides a zinc-based rust-resistant coating that extends service life in both indoor and outdoor installations. Licensed plumbers and pipefitters install this fitting to seal off unused branch lines, decommission sections of pipe, or cap temporary openings during pressure testing. At 1.37 pounds packaged, it ships as a single unit and threads directly onto standard 1/2 inch male-threaded pipe ends.

This cap is suited for a range of low-pressure piping applications including potable water supply lines, compressed air distribution systems, and drainage configurations. It is also used in light industrial and general mechanical installations where a threaded galvanized cap is required to close off a pipe end cleanly and permanently. DIY applications such as custom pipe fabrication projects are another common use case.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off water supply or depressurize the compressed air line completely before threading the cap onto the pipe. Apply thread sealant tape or pipe dope to the male threads before installation to ensure a leak-free connection. Do not overtighten, as this can crack the fitting or damage the pipe threads.
