The ASC ENGINEERED SOLUTIONS 4354000900 is a black steel seamless extra heavy (XH) pipe nipple sized at 3/8 inch by 6 inches. Manufactured to ASTM A106B standards, this nipple provides a threaded pipe extension or connection point in piping assemblies that demand heavier wall thickness than standard weight. The seamless construction eliminates a weld seam, which reduces the risk of failure under pressure and thermal cycling. Plumbers, pipefitters, and mechanical contractors install this type of fitting in gas, steam, and industrial fluid systems where extra wall strength is specified.
This nipple is suited for commercial and industrial piping applications where ASTM A106B seamless black steel is required. Common uses include gas distribution headers, steam lines, and compressed air systems requiring extra heavy fittings. The 3/8 inch diameter and 6 inch length make it appropriate for close-quarter runs and branch connections. This is a non-domestic import product.
Designed as an OEM-style replacement or direct-install fitting for threaded black steel piping systems requiring 3/8 inch extra heavy seamless nipples per ASTM A106B specifications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC or ASME B31 piping standards. Shut off and depressurize the piping system fully before removing or installing any threaded fitting. Apply appropriate pipe thread sealant or PTFE tape rated for the service medium. Do not over-torque threaded connections, as this can damage threads or fittings.
