The ASC Engineered Solutions 830011805 is a black steel pipe nipple sized at 3/8 inch by 6 inches. It is a short threaded pipe section used to connect two female-threaded fittings or to extend a pipe run in gas, air, or fluid distribution systems. Made from black steel, it is commonly found in natural gas and propane lines, as well as compressed air and hydronic heating applications. Licensed plumbers, pipefitters, and HVAC technicians install this type of nipple during new construction, service calls, and piping modifications where a close or short extension is needed.
This nipple is suited for residential and light commercial piping systems where black steel is the specified material. Typical installations include gas supply lines to furnaces, boilers, water heaters, and commercial cooking equipment, as well as compressed air distribution headers. The 3/8 inch diameter makes it a common size for branch lines and low-flow supply drops off a main distribution run.
Designed as an OEM-style replacement or standard stock nipple for black steel threaded piping systems requiring a 3/8 inch by 6 inch close or short extension fitting.
Installation of black steel pipe nipples is typically performed by licensed plumbers or pipefitters following applicable codes such as the IFGC or IPC. Always shut off and depressurize the gas or fluid supply before threading or unthreading any fitting. Apply an approved pipe thread sealant or PTFE tape rated for the service medium to all threaded connections before assembly. Do not over-tighten threaded connections, as black steel threads can be damaged by excessive force.
