Ndl Industries NIPPLE2X41/2 Black Iron Pipe Nipple

Product Description

The NDL INDUSTRIES NIPPLE2X41/2 is an extra heavy (XH) black iron pipe nipple used to connect threaded pipe sections in gas, steam, and industrial plumbing systems. Measuring 2 inches in nominal diameter and 4.5 inches in length, this nipple provides a rigid, durable threaded connection point for high-demand piping runs. The extra heavy wall construction offers greater pressure tolerance than standard-weight fittings, making it a practical choice where heavier-duty service conditions apply. Licensed plumbers, pipefitters, and gas line technicians are the typical installers.

This black iron nipple is suited for residential and commercial gas distribution piping, steam systems, and general industrial plumbing applications where black iron is specified. The uncoated black iron finish is standard for gas supply lines and is compatible with black iron pipe and fittings throughout those systems. It is not intended for potable water lines or outdoor use without corrosion protection.

Key Features

• Extra heavy (XH) wall construction for higher pressure tolerance than standard-weight nipples
• 2-inch nominal diameter with 4.5-inch face-to-face length
• Black iron material standard for gas piping applications
• Threaded ends for direct connection to standard black iron fittings and pipe
• Compact length suitable for close-quarter fitting configurations

Compatibility

Designed as an OEM-style replacement fitting for use in black iron threaded pipe systems requiring a 2-inch by 4.5-inch extra heavy nipple.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC requirements for gas piping systems. Shut off and depressurize the line before removing or installing any threaded fittings. Apply an appropriate pipe thread sealant rated for the service fluid before making up threaded joints. Do not overtighten threaded connections, as this may damage threads or crack fittings.
