The ASC ENGINEERED SOLUTIONS 4354002020 is a black steel seamless extra heavy (XH) pipe nipple sized at 1 inch x 2.5 inches. It is manufactured to ASTM A106B specifications, making it suitable for high-pressure and high-temperature piping applications. The seamless construction eliminates a weld seam, which improves structural integrity under stress. Licensed plumbers and pipefitters install this type of nipple as a short threaded connector between pipe fittings, valves, or equipment in industrial, commercial, and mechanical piping systems. At 0.37 pounds, it is a compact fitting designed for secure, leak-resistant threaded connections.
This nipple is used in steam, gas, water, and other fluid piping systems where extra heavy wall thickness is required for added pressure capacity or mechanical durability. Its black steel finish makes it appropriate for natural gas lines, steam distribution, and industrial process piping where corrosion protection is managed externally. It is not intended for potable water service without appropriate lining or coating. The extra heavy wall designation means it carries a thicker pipe wall than standard or schedule 40 fittings, which is often required in commercial mechanical rooms and industrial installations.
Designed as an OEM-style replacement or standard component for 1-inch threaded black steel piping systems requiring extra heavy wall seamless nipples in commercial or industrial applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off all system pressure and drain the line before removing or installing threaded nipples. Apply appropriate thread sealant or PTFE tape to the male threads before makeup. Do not overtighten threaded connections, as this can crack fittings or damage threads.
