Value Collection MSCNB03035 Black Pipe Nipple 3/8x3.5in Sch40

Product Description

The VALUE COLLECTION MSCNB03035 is a Schedule 40 black steel pipe nipple used to connect threaded pipe sections in plumbing, gas, and mechanical systems. It measures 3/8 inch in diameter and 3-1/2 inches in length, with male NPT threads on both ends. The welded steel construction delivers the wall thickness and pressure tolerance required for typical Schedule 40 service. Licensed plumbers, pipefitters, and HVAC technicians install this type of nipple when making close-coupled connections between fittings, valves, and threaded pipe runs.

This nipple is suited for residential and light commercial applications including natural gas supply lines, steam and hydronic heating systems, compressed air distribution, and general water service where black iron pipe is specified. The MNPT x MNPT thread configuration makes it a direct fit into standard NPT female-threaded fittings, valves, and couplings without adapters. The black finish is standard for gas piping installations where galvanized fittings are not permitted.

Key Features

• Schedule 40 wall thickness for standard-service pressure ratings
• Welded steel construction for consistent dimensional integrity
• Male NPT threads on both ends for direct threaded assembly
• Black finish appropriate for gas line and mechanical piping service
• 3/8 inch pipe size x 3-1/2 inch length for close-coupled runs

Compatibility

Designed as a standard replacement or new-installation fitting for Schedule 40 threaded pipe systems using 3/8 inch NPT connections in plumbing, gas, and mechanical piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the supply line fully before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and tighten to a proper thread engagement using a pipe wrench — do not over-tighten, as this can crack fittings or damage threads. On gas systems, verify all connections with an approved leak-detection solution after pressurizing.
