Brass Pipe Nipple 1-1/2 MNPT

This brass pipe nipple provides a 1-1/2 inch male NPT connection for plumbing installations. It suits professionals and DIYers joining threaded fittings in water or gas lines. The 20 inch length offers reach between components. Schedule 40 wall thickness handles standard residential and commercial pressures.

20 Inch Length and Schedule 40 Rating

The 20 inch TBE barrel spans gaps between tees, elbows or valves without extra couplings. Schedule 40 brass withstands typical supply pressures and resists corrosion in potable water systems. Threaded both ends allow direct engagement with female NPT fittings. Longer runs or higher-pressure mains exceed the design intent of this single nipple.

1-1/2 Inch MNPT Thread Size

The 1-1/2 inch male NPT thread determines compatibility with matching female fittings. Installers must verify that the mating components share this exact thread standard. Brass construction suits water, air and inert gas services where the material is approved. Systems requiring different thread forms or larger diameters need alternative fittings.

Questions about this item

Will the 1-1/2" MNPT threads on this Smith-Cooper nipple match my existing 1-1/2" Schedule 40 fittings?

Yes, the MNPT threads follow the standard taper for 1-1/2" pipe size, so they engage correctly with any matching 1-1/2" FNPT fitting made to the same Schedule 40 dimensions.

How can I verify the nipple is seated properly after threading it into my drain assembly?

Turn the nipple until the brass faces are flush with the fitting shoulders; a snug metal-to-metal seal with no visible thread gaps indicates correct engagement.

Does the 4385013030 come with thread sealant or gaskets, or must I buy them separately?

The nipple ships as a single brass piece with no sealant, tape, or gaskets included; you will need to supply PTFE tape or pipe dope for the MNPT joints.
