Nipples 330026006 Black Steel Pipe Nipple 1 in X 7 in Npt

Product Description

The NIPPLES 330026006 is a domestic black steel pipe nipple sized at 1 inch diameter by 7 inches in length, threaded on both ends with NPT threads conforming to ASME B1.20.1. Manufactured from ASTM A53 welded steel pipe and dimensioned to ASTM A733 standards, this nipple is built for reliable performance in piping systems that carry gas, water, steam, or compressed air. The black finish is standard for gas-line applications in residential and commercial mechanical systems. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting as part of supply and distribution piping runs.

This nipple fits standard 1-inch pipe applications in residential and light commercial settings. It is commonly used in natural gas supply lines, hydronic heating systems, compressed air distribution, and general-purpose plumbing piping. The 7-inch length makes it useful when a longer close nipple or short-run extension is needed between fittings or equipment connections. Figure No. 339 designation applies. Beck pipe nipples are available seamless and welded across all schedules, supporting a wide range of pressure-class requirements.

Compatibility

Designed as a standard replacement or new-installation fitting for 1-inch NPT threaded piping systems. Compatible with standard and extra heavy threaded fittings, valves, and couplings in 1-inch pipe size.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on service type. Shut off the gas or water supply and depressurize the system before making any threaded connections. Apply an appropriate thread sealant or PTFE tape rated for the service medium before assembly. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
