Matco-norca mn-znb006 Black Steel Nipple 1/8x6 Sch 40

Product Description

The MATCO-NORCA mn-znb006 is a black steel pipe nipple designed for low-pressure piping assemblies in plumbing, gas distribution, and mechanical systems. It measures 1/8 inch in diameter and 6 inches in length, with male NPT (MNPT) threads on both ends for straightforward inline connections. Manufactured from welded steel to ASTM A53/A53M standards and rated Schedule 40, this nipple provides consistent wall thickness and reliable thread engagement. The black finish is standard for gas-line applications. Licensed plumbers and pipefitters install this type of fitting during rough-in and system assembly work.

This nipple is suited for residential and light commercial piping systems where 1/8-inch MNPT connections are required. Common applications include gas supply branch lines, steam and air distribution headers, and general-purpose black iron pipe assemblies. The 6-inch length makes it useful for close-quarter offsets and extensions between fittings, valves, or equipment connections where a close nipple or short nipple would not span the required gap.

Key Features

• 1/8 inch MNPT threads on both ends for standard inline connection
• 6-inch length suits offsets and extensions in tight piping runs
• Schedule 40 wall rating per ASTM A53/A53M material standard
• Welded steel construction for consistent dimensional tolerances
• Black finish appropriate for gas-line and steam piping service

Compatibility

Designed as an OEM-style replacement or new-installation component compatible with standard 1/8-inch MNPT black iron pipe fittings, valves, and threaded equipment ports in residential and commercial piping systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes, including IFGC requirements for gas piping. Shut off and verify zero pressure in the line before cutting into any existing piping system. Apply listed thread sealant or PTFE tape to male threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or damage valve bodies.
