Matco-norca mn-znb078 Black Steel Nipple 1.5x8 in

Product Description

The MATCO-NORCA mn-znb078 is a black steel pipe nipple sized at 1.5 inches in diameter and 8 inches in length. Pipe nipples are short sections of pipe threaded on both ends, used to connect two fittings, valves, or other piping components in a run. This nipple is finished in black, indicating standard carbon steel without galvanizing, which is common in gas piping, industrial, and mechanical applications. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting when assembling or extending threaded pipe systems in both new construction and retrofit work.

This nipple is suited for residential and light commercial gas supply lines, steam heating systems, and general-purpose black iron piping assemblies. The 1.5-inch diameter and 8-inch length make it appropriate for medium-capacity runs where a standard close or short nipple would be insufficient. It threads directly into compatible black iron fittings, tees, elbows, unions, and valves using standard NPT connections.

Key Features

• Black carbon steel construction without galvanizing, compatible with natural gas and propane piping applications
• 1.5-inch nominal diameter suits medium-flow piping runs
• 8-inch length provides clearance and offset capability in tight assemblies
• Threaded on both ends for direct connection to standard NPT fittings and valves
• Black finish is conventional for gas distribution piping in residential and commercial systems

Compatibility

Designed as a standard replacement or extension nipple for threaded black iron piping systems using 1.5-inch NPT connections.

Installation Notes

Installation of black iron pipe nipples in gas systems must be performed by a licensed plumber or gas fitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC). Shut off the gas supply and verify zero pressure at the line before disassembling or extending any piping. Apply an approved pipe thread sealant or PTFE tape rated for gas service to all male threads before assembly. Pressure-test the completed assembly per local code requirements before returning the system to service.
