Matco-norca znb00312 Black Steel Pipe Nipple 1/8 in Mnpt

Product Description

The MATCO-NORCA znb00312 is a black steel pipe nipple designed for low-pressure piping systems in plumbing, HVAC, and gas distribution applications. It features 1/8-inch Male National Pipe Taper (MNPT) threads on both ends and measures 3.5 inches in length. Constructed from Schedule 40 steel with a black finish, it provides the wall thickness and durability required for standard threaded pipe assemblies. Licensed plumbers and pipefitters install this fitting when connecting small-diameter threaded pipe runs, extending existing lines, or making up close-coupled assemblies at valves, gauges, or fittings.

This nipple is suited for residential and light commercial piping systems where 1/8-inch threaded connections are required. Typical applications include gas pilot supply lines, instrument tap connections, pressure gauge ports, and small-bore water or air distribution lines. The black steel finish is standard for gas service piping in many jurisdictions. Its SCH 40 wall rating makes it appropriate for systems operating within standard low-pressure service parameters.

Key Features

• 1/8-inch MNPT x 1/8-inch MNPT threaded ends for standard pipe assembly
• 3.5-inch body length for short-run extensions and close-coupled connections
• Schedule 40 wall thickness for adequate strength in low-pressure service
• Black steel construction standard for gas distribution piping
• Straight nipple configuration compatible with standard threaded fittings and valves

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 1/8-inch NPT threaded pipe systems using Schedule 40 black steel components.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where applicable. Apply an approved thread sealant or PTFE tape rated for the intended service medium before making up connections. Ensure the system is fully depressurized and isolated before removing or installing any threaded fitting. Do not over-tighten threaded connections, as this can crack fittings or distort threads.
