Value Collection MSCXNB03040 Black Pipe Nipple Sch 80

Product Description

The VALUE COLLECTION MSCXNB03040 is a Schedule 80 seamless black pipe nipple used to connect sections of threaded pipe in plumbing, HVAC, and industrial piping systems. It measures 3/8 inch nominal pipe size and 4 inches in length, with male NPT threads on both ends. Schedule 80 wall thickness provides greater pressure tolerance compared to standard Schedule 40 pipe. The seamless construction eliminates weld seams, resulting in a more uniform bore and consistent wall thickness throughout. Licensed plumbers and pipefitters install this type of nipple in close-quarter runs where a short threaded connection is required between fittings, valves, or equipment.

This black pipe nipple is suited for residential and commercial applications including gas distribution lines, steam systems, air lines, and general-purpose liquid or vapor piping where black iron is the specified material. The MNPT x MNPT thread configuration makes it compatible with standard NPT female fittings. Its compact 4-inch length fits tight installation spaces between valves, unions, or pipe couplings in both new construction and retrofit service work.

Key Features

• Schedule 80 wall thickness for higher pressure-rated applications compared to Schedule 40
• Seamless construction for uniform wall thickness and a clean bore
• MNPT x MNPT thread ends for direct connection to standard NPT female fittings
• 3/8 inch nominal pipe size suitable for smaller-diameter gas, air, or fluid lines
• 4-inch length designed for close-quarter runs between fittings or equipment ports

Compatibility

Designed as an OEM-style replacement or standard-stock nipple for use with 3/8 inch NPT female threaded fittings, couplings, valves, and equipment ports in Schedule 80 black iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where gas service is involved. Shut off all system pressure and depressurize the line before removing or installing any threaded nipple. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Avoid over-tightening, which can crack fittings or distort thread engagement.
