B K/mueller Inds(import) 583-035HC Black Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 583-035HC is a black steel pipe nipple sized at 1/2 inch nominal diameter by 3-1/2 inches in length. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other threaded components in a piping system. This nipple ships in a package quantity of 25 pieces and is commonly installed by licensed plumbers and pipefitters working on gas distribution, steam, or liquid piping systems where black iron pipe is specified. The black finish is the standard bare steel treatment used throughout gas supply and industrial piping applications.

Black pipe nipples at this size are widely used in residential and light commercial gas piping systems, including natural gas and propane supply lines running to appliances such as furnaces, boilers, water heaters, and ranges. They are also found in steam heating systems and general industrial fluid piping. The 1/2 inch by 3-1/2 inch dimension makes this a common close-quarter connection piece where a standard close or longer nipple would not fit cleanly.

Key Features

• 1/2 inch nominal diameter with 3-1/2 inch overall length for close-quarter piping runs
• Black steel construction suited for gas, steam, and non-potable fluid systems
• Threaded both ends for standard NPT fitting connections
• Sold in a package of 25 pieces for service stock or project quantities

Compatibility

Designed as a standard replacement or new-installation black iron pipe nipple compatible with 1/2 inch NPT threaded fittings, valves, and couplings used in gas and steam piping systems.

Installation Notes

Black pipe nipples are installed by licensed plumbers, gasfitters, or pipefitters in accordance with applicable codes including the IFGC and IPC. Shut off gas supply and depressurize the line before removing or installing any threaded pipe component. Apply an appropriate thread sealant or pipe dope rated for the service medium to all male threads before assembly. Do not overtighten threaded connections; follow standard hand-tight-plus-turns practice and verify all joints for leaks after restoring pressure.
