The ASC ENGINEERED SOLUTIONS 830055604 is a black steel pipe nipple sized at 4 inches x 9 inches and weighing 7.07 pounds. This close-cut threaded fitting connects sections of pipe in low-pressure fluid and gas distribution systems. Black steel nipples are a standard component in commercial and industrial piping assemblies, used where corrosion protection is not the primary concern and where the system will be painted, coated, or used in dry interior applications. Licensed plumbers and pipefitters install these fittings as part of gas supply lines, fire suppression headers, and general mechanical piping systems.
This nipple is suited for commercial and industrial plumbing and mechanical piping applications where a 4-inch nominal pipe size is required. The 9-inch length makes it appropriate for spanning short distances between fittings, valves, or equipment connections. It is commonly found in building gas distribution headers, steam systems, and black iron piping assemblies in both new construction and retrofit work.
Designed as a standard-thread black steel pipe nipple for use with 4-inch nominal schedule pipe fittings in commercial and industrial mechanical piping systems.
Installation is performed by licensed plumbers or pipefitters. Shut off all gas or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape rated for the intended service to all male threads before assembly. Verify that the installation meets applicable local codes and IFGC or IPC requirements for the system type.
