B K/mueller Inds(import) 583-015HN Black Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 583-015HN is a black steel pipe nipple measuring 1/2 inch nominal pipe size by 1-1/2 inches in length. Pipe nipples are short threaded pipe sections used to connect two female-threaded fittings or to extend a pipe run. This nipple is finished in black iron, making it a standard choice for gas distribution, compressed air, and other non-potable piping systems. It is installed by licensed plumbers, pipefitters, and HVAC technicians in both residential and commercial applications. The package contains 20 pieces, making it practical for jobs requiring multiple connections.

This black pipe nipple is suited for use in gas supply lines, steam systems, and industrial air piping where black iron pipe is the specified material. The 1/2 inch nominal size is among the most common in residential gas branch lines and commercial piping rough-ins. It is typically installed in tandem with black malleable iron fittings such as couplings, tees, and elbows. Contractors stocking service vehicles or supply rooms will find the 20-unit package count useful for routine work.

Installation Notes

Black iron pipe nipples are installed by licensed plumbers or pipefitters in accordance with the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as applicable. Always shut off the gas supply or depressurize the system before disconnecting or adding fittings. Apply an approved thread sealant or pipe thread compound rated for the intended service medium to all threaded joints. Inspect threads for damage before installation and do not over-tighten, as this can crack fittings.
