Brass Pipe Nipple Sch 40

This Smith-Cooper brass pipe nipple measures 3 inches by 48 inches and carries a Schedule 40 rating. It features male NPT threads on both ends for standard plumbing connections. The fitting is supplied new and listed by the manufacturer in 2022.

Suited for threaded brass pipe runs

Installers joining two female-threaded components in water or gas lines will find this nipple matches the required diameter and wall thickness. Projects that need a different length, diameter, material or schedule should select another fitting.

Schedule 40 wall thickness

Questions about this item

How do I install the 3" MNPT brass nipple without cross-threading the tapered threads?

Start the nipple by hand for at least three full turns to align the NPT taper before using a pipe wrench on the hex flats; forcing it with tools first is the step most installers get wrong.

What maintenance will the brass nipple need after years in a drain line?

Inspect the threads and interior annually for mineral scale or dezincification; replace the nipple if the bore narrows or threads show pitting.

What limit appears first when the Sch 40 brass nipple runs hot water continuously?

The brass expands faster than steel piping, so the joint can loosen before the Sch 40 wall reaches its pressure rating.
