Matco-norca znb0211 Black Steel Pipe Nipple 3/8x1.5 in

Product Description

The MATCO-NORCA znb0211 is a black steel pipe nipple designed for use in threaded piping systems where a short close-nipple connection is required. Manufactured from ASTM A53/A53M Grade B ERW welded steel, this Schedule 40 nipple measures 3/8 inch in diameter and 1-1/2 inches in overall length. Both ends are male NPT threaded per ASME B1.20.1, making it a direct drop-in for standard threaded fittings. The black finish is applied over the bare steel and is typical for gas, oil, and general-purpose piping installations. Plumbers, pipefitters, and mechanical contractors install this type of nipple in commercial and residential systems.

This nipple is suited for residential and light commercial plumbing, gas distribution, and mechanical piping applications where Schedule 40 black steel is specified. The 3/8 inch size is commonly used in branch lines for natural gas, propane, and hydronic heating systems. Its compliance with NSF 61/372 makes it appropriate for use in potable water systems where lead-free fittings are required by code. ASTM A733 and ISO 9001 compliance confirms dimensional and quality standards are met.

Key Features

• Schedule 40 wall thickness for standard-duty threaded piping systems
• ASTM A53/A53M Grade B ERW welded steel construction
• Male NPT threads on both ends per ASME B1.20.1
• NSF 61/372 listed and lead-free for potable water compatibility
• RoHS compliant
• Black finish for gas and general mechanical piping use

Compatibility

Designed as an OEM-style replacement or new-installation component for standard 3/8 inch NPT threaded piping systems using Schedule 40 black steel pipe and fittings.

Installation Notes

This nipple is installed by licensed plumbers or pipefitters using pipe wrenches and appropriate thread sealant or PTFE tape rated for the intended service. Shut off and depressurize the piping system fully before removing or installing any threaded fitting. For gas piping, follow local amendments to the IFGC and verify all joints with an approved leak-detection solution after pressurization. Do not over-torque threaded connections on steel nipples as this can damage fitting threads.
