Nipples 330541004 Xh Black Cw Nipple 2.5x3.5 in

Product Description

The NIPPLES 330541004 is an extra heavy (XH) black continuous weld pipe nipple sized at 2.5 inches by 3.5 inches. Continuous weld construction produces a seam-welded steel tube that is rolled and forge-welded along its length, resulting in a dense, heavy-wall fitting suited for demanding pipe assemblies. The black finish is a standard mill coating applied to carbon steel to inhibit surface oxidation during storage and installation. This nipple is installed by licensed plumbers, pipefitters, and mechanical contractors working on gas, steam, and industrial piping systems where extra heavy wall thickness is specified.

Extra heavy black nipples like the 330541004 are commonly used in commercial and industrial piping systems where standard-weight fittings do not meet pressure or durability requirements. Typical applications include natural gas distribution, low-pressure steam lines, compressed air headers, and process piping. The 2.5-inch diameter and 3.5-inch length make this nipple suitable for close-coupled connections and short offset runs in threaded piping assemblies.

Key Features

• Extra heavy (XH) wall construction for higher-pressure and heavy-duty piping applications
• Continuous weld manufacturing for consistent wall integrity along the full length
• Black mill-coat finish provides basic corrosion resistance during storage and service
• 2.5-inch nominal diameter with 3.5-inch overall length for close-coupled threaded runs
• Manufactured in the United States

Compatibility

Designed as an OEM-style threaded pipe nipple for use in 2.5-inch NPT threaded piping systems requiring extra heavy wall fittings.

Installation Notes

Installation of threaded black steel pipe nipples is typically performed by licensed plumbers or pipefitters in accordance with applicable mechanical and fuel gas codes, including IFGC and ASME B31 standards where required. Always depressurize and isolate the piping system before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium. Do not overtighten threaded connections, as excess torque can crack fittings or damage threads.
