Asc 4354000840 Black Steel Xh Nipple 3/8 X 3 Inch

Product Description

The ASC ENGINEERED SOLUTIONS 4354000840 is a black steel seamless extra heavy (XH) pipe nipple sized at 3/8 inch by 3 inches. Manufactured to ASTM A106B standards, it is designed for close-coupled pipe connections in high-pressure and high-temperature piping systems. The seamless construction eliminates weld seams, reducing potential failure points under elevated stress. Weighing 0.17 pounds, this nipple suits applications where standard-weight fittings are not rated for the system demands. Licensed plumbers and pipefitters install this type of fitting in gas, steam, and fluid piping assemblies.

This nipple is used in residential and commercial piping installations where extra heavy wall thickness is required. Common applications include natural gas distribution lines, steam systems, and industrial fluid transfer piping. The 3/8 inch by 3 inch sizing fits tight-clearance runs where a short, rigid threaded connection is needed between pipe sections or fittings. Import origin makes this a cost-effective option for projects requiring ASTM A106B seamless construction without domestic sourcing requirements.

Key Features

• Seamless extra heavy (XH) wall construction per ASTM A106B for elevated pressure and temperature service
• Black steel material suited for gas, steam, and non-potable fluid piping
• 3/8 inch by 3 inch dimensions for close-coupled or short-run threaded connections
• Lightweight at 0.17 pounds, minimizing added load on piping systems
• Threaded ends for standard NPT pipe assembly

Compatibility

Designed as an OEM-style replacement or stock fitting for extra heavy black steel threaded piping systems using 3/8 inch NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the piping system completely before removing or installing any threaded nipple. Apply an appropriate pipe thread sealant or PTFE tape rated for the service fluid before making up threads. Do not over-tighten threaded connections, as black steel nipples can crack at the threads if excessive force is applied.
