Red Brass Pipe Nipple 2 in MNPT

This new Zoro Select pipe nipple is a 2 in MNPT by 3-1/2 in TBE Schedule 80 fitting made from seamless red brass to ASTM B43 grade. It suits plumbing and industrial systems that convey air, natural gas, oil, potable water or steam where a durable, corrosion-resistant connection is required.

Sustained Pressure and Temperature Limits

Under continuous service the nipple handles up to 157 psi at 450 Degrees F and up to 625 psi for steam at 300 Degrees F. The seamless construction and Class 300 fitting compatibility support these ratings without degradation, while the minimum operating temperature extends to -20 Degrees F for cold-environment installations.

Sch 80 Dimensional Constraints

The Schedule 80 wall thickness fixes the outside diameter at 2 3/8 in and the inside diameter at 2 in, limiting flow capacity to what that bore allows. Threaded MNPT and TBE ends dictate the mating components, and the 3-1/2 in overall length determines the installed centre-to-centre spacing in the piping run.

Questions about this item

Does the 2-inch MNPT red brass nipple handle continuous steam at 625 psi without overheating?

The nipple is rated for a maximum steam pressure of 625 psi at 300 degrees F and a maximum operating temperature of 400 degrees F, so it will not overheat under those conditions.

Which piping standard and thread type must the existing system use to mate with this Schedule 80 nipple?

The nipple has 2-inch MNPT threads and is manufactured to ASTM B43 Grade red brass, so the mating pipe must also be NPT and rated for Schedule 80 or higher.

Will the 2-inch nominal bore and 2 3/8-inch outside diameter align with older Class 300 flanges I already have?

The nipple is built for Fitting Compatibility Class 300 with a 2-inch nominal pipe size and 2 3/8-inch outside diameter, matching standard Class 300 flange dimensions.
