The ASC Engineered Solutions 4354000830 is a black steel seamless extra heavy (XH) pipe nipple sized at 3/8 inch x 2-1/2 inches. It is manufactured to ASTM A106B seamless specifications, making it suitable for high-pressure and high-temperature piping systems. The extra heavy wall construction provides added strength over standard-weight nipples, reducing the risk of failure under elevated system pressures. Plumbers, pipefitters, and mechanical contractors install this type of nipple to connect threaded pipe sections in close-quarter or tight-run configurations across a range of commercial and industrial piping systems.
This nipple is used in gas distribution, steam, water, and hydraulic piping systems where a short threaded connector is required between fittings, valves, or equipment ports. The 3/8 inch diameter and 2-1/2 inch length make it well suited for branch connections, equipment tie-ins, and panel or manifold assemblies. Its seamless construction eliminates weld seams, which is preferred in systems subject to pressure cycling or mechanical vibration.
Designed as an OEM-style replacement or new-installation fitting for threaded black steel piping systems requiring 3/8 inch extra heavy seamless nipples.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including IFGC and IPC where relevant. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or tape rated for the service fluid before making up connections. Do not over-tighten threaded joints, as this can crack fittings or damage threads.
