B K/mueller Inds(import) 585-045HN Black Steel Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 585-045HN is a black steel pipe nipple used to create threaded connections in gas, air, and fluid piping systems. This close-cut nipple measures 1 inch in diameter and 4.5 inches in length, providing a short, rigid connection between fittings, valves, and other threaded pipe components. Sold in a package of 5, this nipple is a standard item for plumbers, pipefitters, and HVAC technicians working on gas distribution, steam, or general-purpose black iron piping systems. The black finish indicates uncoated steel, which is standard practice for gas piping applications.

This pipe nipple is suited for residential and light commercial installations where threaded black iron pipe is specified. Common applications include natural gas supply lines, propane distribution, air compressor lines, and steam or hydronic heating systems. Installers typically use these nipples to make up short runs between a valve body and a fitting or to extend an existing threaded pipe assembly by a fixed length. The 5-unit pack supports service calls where multiple connections are required.

Installation Notes

Black iron pipe nipples are typically installed by licensed plumbers or pipefitters. Always shut off the gas supply or depressurize the system before breaking any threaded connection. Apply an approved pipe thread sealant or PTFE tape rated for the service medium before threading the nipple into fittings. Gas piping installations must comply with applicable local codes and the International Fuel Gas Code (IFGC).
