Anvil 3/4" MNPT x 4" Galvanized Steel Nipple

This Anvil pipe nipple is a 3/4 inch male NPT threaded fitting made from welded Grade B steel with a black anodized finish. It measures four inches in overall length and carries a Schedule 40 wall thickness rated for 150 psi at 150 degrees Fahrenheit. The nipple is manufactured in the USA and suits air, gas, non-potable water, oil and steam applications.

Who this fits and who it does not

Plumbers and maintenance technicians needing a short, male-threaded Schedule 40 steel nipple for 3/4 inch nominal pipe will find this part matches the spec. Installers requiring a different length, a female thread, a Schedule 80 wall or a fitting rated above 150 psi should select another product.

Deciding specification: Schedule 40 at 150 psi

The single figure that confirms the right part is the Schedule 40 rating combined with the 150 psi maximum operating pressure at 150 degrees F. If the system calls for Schedule 80 or a higher pressure class, this nipple will not meet the requirement.

Questions about this item

What thread size and length does this 3/4 in MNPT nipple need for a matching fitting?

The nipple has a 3/4 in male NPT thread and an overall length of 4 in, so the mating fitting must accept a 3/4 in female NPT connection.

How do I install this Schedule 40 steel nipple without damaging the threads?

Apply pipe-thread sealant or tape to the male threads, hand-tighten into the female fitting, then finish with a wrench no more than one to two turns past hand-tight to avoid cracking the fitting.

When should I plan to replace this galvanized steel nipple in a steam line rated at 150 psi?

Inspect annually for corrosion, scale buildup or thread deformation; replace if wall loss is visible or if the 150 psi @ 150 °F rating can no longer be maintained.
