Brass Sch 40 Pipe Nipple

This Smith-Cooper brass pipe nipple connects two female-threaded components in a plumbing system. It features 1-1/2 inch MNPT threads on one end and a 3-1/2 inch TBE length. The Schedule 40 wall thickness handles standard pressure requirements for water and gas lines.

For standard threaded connections only

Installers joining two female fittings with a straight male nipple will find this part suitable. It does not suit systems requiring a reducing nipple, a close nipple, or a different thread standard such as BSPT. Buyers needing a longer or shorter overall length must select a different model.

1-1/2 inch MNPT thread size

The male National Pipe Taper thread diameter is the critical specification for compatibility. It must match the female thread size of the connecting fittings exactly. Verify the required thread size and TBE length against your system design before purchase.

Questions about this item

What thread size must the mating fitting have to connect to the 1-1/2" MNPT end?

The nipple has a 1-1/2 inch male NPT thread, so the joining fitting needs a matching 1-1/2 inch female NPT thread.

Can this Schedule 40 brass nipple be used with existing Schedule 40 piping of the same nominal size?

Yes, the Schedule 40 wall thickness matches standard Schedule 40 pipe, so it threads directly into 1-1/2 inch Schedule 40 fittings.

How can I confirm the nipple is seated correctly after threading it into both fittings?

The 3-1/2 inch TBE length will be the visible distance between the two engaged fittings when the joint is fully made up.
