The ASC Engineered Solutions 4354003260 is a black steel seamless extra heavy (XH) pipe nipple sized at 2 inches by 5 inches. Manufactured to ASTM A106B standards, this nipple provides a reliable threaded connection between pipe sections in high-pressure and high-temperature piping systems. The extra heavy wall construction offers greater pressure ratings than standard weight nipples, making it well suited for demanding industrial and commercial applications. Licensed plumbers, pipefitters, and mechanical contractors typically specify this fitting where code or system design calls for XH schedule pipe components.
This nipple is used in commercial and industrial piping systems where elevated pressure or temperature service conditions require heavier wall thickness. Common applications include steam distribution, compressed air, gas piping, and hydronic heating systems. The black steel finish and A106B seamless construction make it appropriate for above-ground and concealed installations in non-corrosive environments where galvanized or coated fittings are not specified.
Designed as an OEM-style replacement or new-installation fitting for 2-inch extra heavy threaded piping systems in commercial and industrial mechanical applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly, and tighten to proper engagement using a pipe wrench. Do not over-tighten, as this can crack fittings or distort threads.
