3/8" Schedule 40 black steel pipe nipple

This 10-inch black steel nipple provides a threaded connection for plumbing assemblies. It suits installers who need a welded Schedule 40 fitting with male NPT threads on both ends. The fitting meets ASTM A-53 Type E and ASTM A-733 Grade B standards for pressure piping. It is not intended for systems requiring larger diameters or different thread standards.

Thermals noise and power in normal use

The steel construction handles a maximum pressure of 300 psi at 150 degrees Fahrenheit during standard operation. It also supports a maximum steam pressure of 150 psi WSP for heating applications. The welded electric resistance seam maintains integrity under these rated conditions. No moving parts or electrical components generate noise or draw power.

Behaviour under sustained load

The 5/64-inch wall thickness and 43/64-inch outside diameter preserve structural strength during continuous pressure cycles. Compliance with ASTM A-53 Type E and Grade B specifications ensures the weld holds under prolonged stress at the 300 psi rating. The WWN 351 classification confirms the dimensional standard for extended service. It is not designed for pressures exceeding the stated maximum ratings.

Questions about this item

How do I install the 3/8" MNPT threaded ends without cross-threading?

Start each end by hand for several turns to ensure the MNPT threads engage straight, then tighten with a wrench on the pipe body — avoid using the threads themselves as leverage points.

Will the black steel nipple need replacement due to corrosion in a water system?

Black steel has no protective coating, so in oxygenated water it will rust internally over time; plan to inspect joints annually and replace the nipple if you see discoloured water or seepage at the threads.

What pressure limit is reached first when the nipple carries 150 °F steam continuously?

The 150 psi WSP steam rating is the governing limit; the 300 psi @ 150 °F water rating does not apply to saturated steam service.
