Ndl Industries NIPPLE1/2X11 Black Iron Pipe Nipple

Product Description

The NDL INDUSTRIES NIPPLE1/2X11 is a black steel pipe nipple in 1/2-inch nominal size with an 11-inch length. Both ends are cut with NPT threads for direct connection to compatible female threaded fittings without additional machining. This nipple is used in threaded piping assemblies across gas distribution, compressed air, and hydronic heating systems where black iron pipe is specified by design or code. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers. Its straight, fixed-length profile makes it a standard close-to-medium length nipple for branch connections, riser drops, and equipment stub-outs.

The NIPPLE1/2X11 is suited for residential and light commercial threaded piping systems where black iron is the specified material. Common applications include natural gas and propane supply lines, compressed air distribution headers, and hydronic heating supply and return runs. Confirm that black iron pipe is permitted by the applicable local code and system pressure rating before specifying this nipple in any installation.

Key Features

• 1/2-inch nominal pipe size with NPT threads on both ends for standard threaded fitment
• 11-inch body length provides a mid-length reach for branch runs and equipment connections
• Black steel construction suitable for gas, air, and hydronic applications where specified
• Threads cut on both ends allow connection directly to female couplings, valves, and fittings without additional preparation

Compatibility

Designed as a standard OEM-style replacement or new-installation component for 1/2-inch NPT threaded piping systems using black iron pipe.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with IFGC, IPC, and applicable local codes. Shut off and depressurize the supply line completely before removing or installing any threaded pipe component. Apply appropriate thread sealant or PTFE tape rated for the intended service medium. Verify nominal pipe size, thread engagement, and system pressure rating before completing the connection.
