The NIPPLES 330541608 is an extra heavy black steel continuous weld nipple measuring 2.5 inches by 5 inches. It is manufactured from black steel using a continuous weld construction, which provides a uniform, seam-welded body suited for high-pressure and heavy-duty piping applications. The extra heavy wall designation indicates a thicker pipe wall than standard or schedule 40 fittings, making it appropriate for systems that demand greater pressure ratings or mechanical strength. Licensed plumbers and pipefitters install this type of nipple in industrial, commercial, and mechanical piping systems.
This nipple is used in black steel pipe assemblies common to gas distribution, steam, compressed air, and hydronic heating systems. The 2.5-inch nominal size and 5-inch length make it suitable for close-coupled connections in larger commercial or industrial pipe runs where extra heavy wall construction is specified. It is manufactured in the United States.
Designed as an OEM-style replacement or direct-fit component for extra heavy black steel pipe assemblies using 2.5-inch nominal threaded fittings in commercial and industrial piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or local mechanical codes. Shut off and depressurize the system completely before removing or installing any pipe nipple. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten threaded connections, as this can damage fittings or compromise the seal.
