Matco-norca mn-znb088 Black Steel Pipe Nipple 2x8 in

Product Description

The MATCO-NORCA mn-znb088 is a black steel pipe nipple measuring 2 inches in diameter and 8 inches in length. Black pipe nipples are threaded fittings used to connect sections of pipe in gas distribution, industrial piping, and general plumbing applications. The black finish comes from an iron oxide coating applied during manufacturing, which distinguishes these nipples from galvanized fittings and makes them a standard choice for natural gas and propane supply lines. Licensed plumbers and pipefitters install these nipples as standard close or extension connections within threaded black iron piping systems.

This nipple is suited for residential and light commercial gas piping, steam systems, and air distribution lines where a threaded black steel fitting is required. The 2-inch diameter and 8-inch length make it appropriate for main branch connections and riser applications in gas supply and hydronic heating systems. It is not recommended for potable water systems where corrosion resistance is critical.

Key Features

• Black steel construction with iron oxide coating for standard gas and steam piping service
• 2-inch nominal diameter with NPT threads on both ends for standard threaded pipe connections
• 8-inch length provides a close-coupled extension between fittings or valves
• Compatible with standard black iron pipe fittings, valves, and couplings
• Suitable for natural gas, propane, steam, and compressed air applications

Compatibility

Designed as a standard OEM-style replacement or new-installation fitting for 2-inch NPT threaded black iron piping systems used in gas, steam, and industrial air distribution applications.

Installation Notes

Installation of black iron gas pipe nipples must be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC). Shut off and verify the absence of gas pressure before making or breaking any threaded connection. Apply an appropriate thread sealant or PTFE tape rated for gas service to all NPT threads before assembly. Do not use black iron nipples on potable water or outdoor exposed applications without verifying local code allowances.
