The ASC Engineered Solutions 4354001680 is a black steel seamless extra heavy (XH) pipe nipple rated for demanding piping applications. Manufactured to ASTM A106 Grade B standards, this nipple is constructed from seamless black steel, providing greater wall thickness than standard-weight fittings for use in higher-pressure or higher-temperature systems. At 3/4 inch by 5 inches, it threads directly into standard NPT fittings and is a common component in gas, steam, and hydraulic piping assemblies. Licensed plumbers and pipefitters typically install this fitting as part of a larger pipe run or service connection.
This nipple is suited for commercial and industrial piping systems where extra heavy wall construction is required. Typical applications include natural gas distribution lines, steam piping, compressed air systems, and hydraulic service runs. The black steel finish makes it appropriate for non-potable water and gas service where corrosion protection is handled by the system design. It is not intended for domestic potable water supply use.
Designed as a standard NPT-threaded extra heavy black steel nipple for use in non-domestic piping systems compatible with 3/4 inch schedule fittings, valves, and pipe couplings.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as appropriate. Shut off the gas supply or depressurize the system before removing or installing pipe nipples. Apply appropriate thread sealant rated for the service type (gas, steam, or air) to NPT threads before assembly. This fitting is not rated for potable water service.
