Brass Pipe Nipple for Plumbing Systems

This Smith-Cooper brass pipe nipple connects two female-threaded fittings in water or gas lines. The 1-1/4 inch MNPT threads mate with standard Schedule 40 components. It suits residential and light-commercial installations where a straight, rigid spacer is required. The transparent finish shows the raw brass surface.

Schedule 40 Wall Thickness Handles Sustained

The Schedule 40 rating means the wall is thick enough for continuous service pressure in hot and cold water systems. Brass resists corrosion and dezincification better than plain steel, so the joint stays tight over years of thermal cycling. Thread engagement remains solid under vibration from pumps or water hammer. No periodic re-tightening is needed.

5-1/2 Inch TBE Length Sets the Fixed Gap

The overall length of five and one-half inches determines the exact centre-to-centre spacing between the two connected fittings. Cutting or threading the nipple shorter is not practical once installed. Verify the required gap before purchase because no adjustment is possible after assembly. The part number 4385012480 identifies this specific length.

Questions about this item

Does the brass nipple heat up or make noise when water runs through it all day?

Brass conducts heat but the nipple itself has no moving parts, so it stays silent and only warms to the water temperature inside.

What pipe fittings must I already have to connect this 1-1/4" MNPT nipple?

You need a matching 1-1/4" female NPT fitting on each end — such as a coupling, elbow or valve — to thread onto the male threads.

Will this Schedule 40 brass nipple thread onto older iron or steel pipe with the same nominal size?

Yes, the 1-1/4" NPT threads are standard, so it mates with existing iron, steel or brass pipe of the same nominal diameter.
