The JONES STEPHENS 35050 is a black steel pipe nipple with a 5-inch diameter and a 5-inch length. Pipe nipples are short threaded sections used to connect fittings, valves, and other piping components within a plumbing or mechanical system. This close-coupled nipple provides a rigid, secure connection point and is suited for gas, water, and steam distribution lines where black steel pipe is specified. Licensed plumbers and pipefitters are the primary installers. The part weighs 6.094 pounds, reflecting the solid steel construction expected in commercial and industrial piping work.
Black pipe nipples like the 35050 are commonly used in residential and commercial gas distribution systems, fire suppression headers, and general-purpose plumbing assemblies. They are also found in hydronic heating systems where black steel is the preferred pipe material. The 5-inch by 5-inch size is a practical stock dimension for mechanical rooms, boiler rooms, and utility piping runs where standard fittings and valves need to be spaced at a fixed offset.
Designed as a standard NPT-threaded black steel pipe nipple for use with compatible 5-inch black iron or steel fittings, valves, and couplings in gas, water, and steam piping systems.
Installation is performed by licensed plumbers or pipefitters following applicable local codes and IFGC or IPC requirements depending on the service. Apply thread sealant or pipe-thread tape rated for the intended service medium before assembly. Ensure the piping system is fully depressurized and isolated before removing or installing any nipple. Do not over-torque threaded connections, as this can crack fittings or damage thread engagement.
