The ASC Engineered Solutions 831041801 is a galvanized steel close-pattern pipe nipple sized at 2.5 inches by 4 inches. It serves as a threaded connector between pipe fittings, valves, and other components in piping systems where corrosion resistance is a priority. The galvanized steel construction provides a zinc coating that resists rust in wet or moderately corrosive environments. Plumbers and pipefitters install this type of nipple in water distribution, heating, and general industrial piping applications. At 1.43 pounds, this nipple is a standard-weight fitting suited for schedule 40 threaded pipe systems.
This nipple is commonly used in residential and light commercial plumbing and mechanical systems where 2.5-inch threaded connections are required. Typical applications include water supply lines, hydronic heating distribution piping, compressed air lines, and general-purpose pipe assemblies. The galvanized finish makes it appropriate for exposed or semi-exposed indoor installations where bare steel would be prone to surface corrosion over time.
Designed as a standard threaded galvanized steel pipe nipple for use with 2.5-inch NPT-compatible fittings, valves, and couplings in residential and commercial piping systems.
Installation is performed by a licensed plumber or pipefitter. Shut off the water supply or system pressure and depressurize the line before removing or installing any threaded fitting. Apply thread sealant tape or pipe dope rated for the service type to all male threads before assembly. Follow applicable IPC or local plumbing code requirements for support spacing and joint preparation on galvanized pipe systems.
