Edmund A. Gray NIPGAL4-12 Galvanized Steel Pipe Nipple 4 Inches X 12 Inches

Product Description

The Edmund A. Gray NIPGAL4-12 is a 4 inches x 12 inches galvanized steel pipe nipple built for demanding plumbing, HVAC, and industrial piping applications. A pipe nipple is a short length of pipe with male NPT threads on both ends. It connects two female-threaded fittings, valves, or pipe sections. This nipple measures 4 inches in diameter and 12 inches in overall length, making it a close-reach extender used where standard couplings alone fall short. The galvanized steel construction means the pipe has been hot-dip coated in zinc. That zinc layer protects against rust and corrosion, which is critical in wet, outdoor, or high-humidity environments. Plumbers, pipefitters, and mechanical contractors rely on galvanized nipples for water supply lines, gas distribution systems, fire protection piping, and industrial process lines. The 4-inch diameter is a large-bore size commonly found in commercial and industrial settings, including boiler rooms, mechanical rooms, and municipal water systems. A 12-inch length gives the installer enough reach to span gaps between flanges, fittings, or equipment connections without cutting and threading custom pipe on the job site. Galvanized steel pipe nipples are compatible with standard NPT fittings and can be used with pipe joint compound or PTFE thread tape to create a leak-free seal. This nipple is suited for use in systems carrying cold water, hot water, air, and certain gas applications where galvanized material is permitted by local code. Keeping galvanized nipples in a variety of sizes on the truck or in the shop reduces downtime and keeps jobs moving. The Edmund A. Gray NIPGAL4-12 is a reliable, code-common pipe fitting for trade professionals who need a 4-inch galvanized nipple with a 12-inch reach.

• 4 inches nominal diameter with male NPT threads on both ends for standard fitting compatibility
• 12 inches overall length provides extended reach between fittings, valves, or equipment connections
• Galvanized steel construction with zinc coating resists rust and corrosion in wet or outdoor environments
