Matco-norca znb028 Black Steel Pipe Nipple 3/8 X 8 in Sch 40

Product Description

The MATCO-NORCA znb028 is a Schedule 40 black steel pipe nipple designed for use in residential, commercial, and industrial piping systems. Manufactured from steel meeting ASTM A53/53M specifications using an electric resistance welded process, Grade B, this nipple measures 3/8 inch in diameter with an overall length of 8 inches. Both ends feature male NPT threads conforming to ASME B1.20.1 standards. The black finish is standard for carbon steel pipe fittings used in gas, air, and general-purpose liquid piping. Licensed plumbers and pipefitters install this fitting as part of threaded pipe assemblies.

This nipple is suited for threaded pipe runs in residential gas distribution, commercial plumbing, and light industrial applications. The 3/8-inch size fits standard branch lines and low-flow service connections. Its Schedule 40 wall thickness handles typical working pressures found in residential and commercial mechanical systems. The lead-free designation makes it appropriate where potable water contact compliance is required under applicable codes.
