The ASC ENGINEERED SOLUTIONS 4354001230 is a black steel seamless extra heavy (XH) pipe nipple sized at 1/2 inch by 2-1/2 inches. Manufactured to ASTM A106 Grade B standards, this nipple is designed for use in high-pressure and high-temperature piping systems where a standard-wall fitting is insufficient. The extra heavy wall construction provides added durability and pressure resistance. Licensed plumbers, pipefitters, and mechanical contractors typically install this type of fitting in steam, gas, oil, and industrial fluid systems where robust, leak-free threaded connections are required.
This nipple is suited for commercial and industrial piping applications where ASTM A106 Grade B seamless black steel is specified. The 1/2 inch by 2-1/2 inch dimension makes it a close nipple replacement commonly used in tight-clearance installations, riser assemblies, and equipment connections. It is appropriate for use in systems requiring extra heavy wall fittings per applicable mechanical and plumbing codes.
Designed as an OEM-style replacement or new-installation fitting for 1/2 inch NPT threaded black steel piping systems requiring extra heavy wall seamless construction per ASTM A106 Grade B.
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 system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service medium before threading the nipple into place. Do not over-tighten, as this can damage threads or connected fittings.
