The ASC Engineered Solutions 8700145801 is a black steel Schedule 40 pipe nipple sized at 3 inches by 3 inches. Pipe nipples are short threaded pipe sections used to join fittings, valves, or equipment in a piping run. This nipple is manufactured domestically and carries the wall thickness of Schedule 40, making it appropriate for standard pressure service in gas, steam, and fluid distribution systems. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting in both residential and light commercial applications where a close or short nipple connection is required.
This nipple is suited for use in black iron piping systems commonly found in natural gas supply lines, propane distribution, steam heating systems, and general industrial fluid service. The 3-inch nominal size and 3-inch length make it a standard close-coupled connector between threaded fittings, flanges, and valves in these systems. It is packaged in quantities of 10 units, making it practical for jobs requiring multiple connections or for stocking a service vehicle.
Designed as an OEM-style replacement or stock fitting for Schedule 40 black iron threaded piping systems using 3-inch nominal pipe size connections.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the intended service. Shut off and depressurize the piping system completely before making or breaking any threaded connections. Use appropriate pipe thread sealant or PTFE tape rated for the service medium, whether gas, steam, or liquid. Inspect threads for damage before installation and do not over-torque, which can crack fittings or strip threads.
