The ASC Engineered Solutions 830031209 is a black steel pipe nipple sized at 1.25 inches in diameter by 9 inches in length. Pipe nipples serve as short threaded connectors used to join sections of pipe or to connect pipe to fittings, valves, and equipment in gas, plumbing, and mechanical systems. This nipple is manufactured from black steel, making it suitable for natural gas, propane, steam, and non-potable water piping applications. It is a standard off-the-shelf connector installed by licensed plumbers, pipefitters, and HVAC technicians during new construction, system retrofits, and repair work.
This nipple is appropriate for residential and light commercial applications where a short close-to-standard length threaded connector is required. Common install scenarios include gas supply lines to appliances, boiler piping, steam distribution headers, and industrial fluid conveyance systems. The 1.25-inch diameter suits medium-capacity branch lines and equipment connections where flow demand exceeds smaller nominal sizes.
Designed as a standard OEM-style replacement or new-installation component for 1.25-inch NPT black steel piping systems in gas, steam, and mechanical fluid applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off the gas supply or isolate the fluid system and relieve pressure before disassembling any piping connections. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all NPT threads before assembly. Do not overtighten threaded connections; follow standard trade practice for hand-tight plus wrench turns appropriate to the fitting material.
