1/2 in NPT Steel Pipe Nipple

This 1/2 in nominal pipe size nipple is manufactured from steel with a black finish. It features threaded NPT connections on both ends and an overall length of 4 1/2 in. The pipe is electric resistance welded and built to Schedule 40 specifications for standard pressure applications.

Suitable for air, natural gas, non-potable water.

Designed for installers needing a Schedule 40 steel nipple rated to 300 psi at 150 Degrees F and 150 psi steam at 350 Degrees F. Not intended for potable water systems or applications requiring corrosion-resistant alloys such as stainless steel or brass.

Schedule 40 wall handles standard industrial

The welded construction and 300 psi pressure rating provide headroom for typical air, gas, oil and low-pressure steam service. At elevated steam temperatures the rating drops to 150 psi, so high-temperature steam systems beyond that limit will require a heavier schedule or alternative material.

Questions about this item

What thread sealant or tape do I need for the 1/2" NPT threads on this nipple?

Use PTFE tape or pipe dope rated for the service fluid — air, natural gas, oil, steam or non-potable water — and wrap the male threads before threading into a Schedule 40 fitting.

Will this black steel nipple handle the same 300 psi at 150 °F as my existing Schedule 40 fittings?

Yes, it is rated 300 psi at 150 °F and 150 psi steam at 350 °F, matching standard Schedule 40 pressure classes for the same nominal size.

How can I confirm the nipple is seated correctly after installation?

Pressure-test the joint to the system working pressure; no leaks at the threaded connections and the 4-1/2" overall length aligning with your layout confirm proper assembly.
