The ASC Engineered Solutions 831045802 is a galvanized steel pipe nipple sized at 3 inches by 4 inches. Pipe nipples serve as short threaded connectors used to join pipe sections, valves, fittings, or equipment in pressurized piping systems. This nipple is fabricated from galvanized steel, providing corrosion resistance in wet or exposed service conditions. It is a standard component installed by licensed plumbers and pipefitters working on water distribution, HVAC hydronic loops, fire protection, and general mechanical piping systems. The threaded ends allow direct makeup to standard pipe fittings and valves without additional adapters.
This nipple is suited for residential and commercial plumbing and mechanical piping applications where a short close-coupled connection is required between fittings or equipment ports. The 3-inch by 4-inch dimensions make it appropriate for mid-to-large diameter piping runs common in commercial hydronic, industrial process, and fire suppression systems. Installation is performed by plumbers and pipefitters following IPC or applicable local mechanical codes.
Designed as an OEM-style replacement or standard-service nipple for galvanized steel threaded pipe systems requiring a 3 inch by 4 inch close connection fitting.
Installation should be performed by a licensed plumber or pipefitter. Shut off system pressure and drain the affected line before removing or installing any threaded pipe component. Apply appropriate thread sealant or PTFE tape to the male threads before makeup, and hand-tighten before applying wrench torque to avoid cross-threading. Verify that the installed nipple meets the pressure and temperature ratings required by the system and applicable code.
