Matco-norca znb049 Black Steel Pipe Nipple 3/4 in 9 in Sch 40

Product Description

The MATCO-NORCA znb049 is a black steel pipe nipple rated to Schedule 40 wall thickness, sized at 3/4 inch MNPT on both ends with a 9-inch body length. It is a close-tolerance, threaded fitting used to extend or connect sections of steel pipe in gas, water, and general-purpose piping systems. The steel construction and black finish make it a standard choice for gas distribution lines and low-pressure fluid systems. Licensed plumbers and pipefitters are the primary installers, though HVAC technicians frequently use black steel nipples when connecting gas supply lines to heating equipment.

This nipple is suited for residential and light commercial applications where a 3/4-inch threaded connection is required. Typical installations include natural gas supply lines feeding furnaces, boilers, water heaters, and unit heaters, as well as general black iron piping assemblies. The 9-inch length provides a useful intermediate extension between close nipples and longer pipe runs, reducing the need for additional couplings in constrained spaces.

Key Features

• Schedule 40 wall thickness for standard-duty pressure applications
• 3/4 inch MNPT threads on both ends for direct inline connection
• 9-inch body length suits mid-range extension needs without added fittings
• Steel construction provides durability in gas and fluid piping service
• Black finish standard for gas line installations per common trade practice

Compatibility

Designed as an OEM-style replacement or new-installation component for 3/4-inch Schedule 40 black steel threaded piping systems used in residential and commercial gas and fluid distribution.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off the gas supply or isolate the fluid system and relieve all pressure before threading or unthreading any fitting. Apply an approved pipe thread sealant or PTFE tape rated for the service medium to all threaded connections before assembly. Do not over-tighten threaded connections; follow standard trade practice for wrench-tight assembly on steel pipe threads.
