Galvanized Steel Pipe Nipple 3" MNPT

This new galvanized steel pipe nipple provides a threaded connection for plumbing systems. It features a continuous weld construction meeting ASTM A-53 Type F and ASTM A733 Grade A standards. The pipe has a nominal size of 3 inches and an overall length of 6 inches. It is rated for a maximum pressure of 150 psi at 150 degrees Fahrenheit.

Suited for Schedule 40 threaded piping

This nipple fits installations requiring Schedule 40 galvanized steel pipe with male NPT threads on both ends. It is not intended for systems specifying stainless steel or plastic materials. Builders needing a different pipe schedule or wall thickness should select an alternative product. The metal detectable construction suits traceable piping requirements.

Pipe Schedule 40 determines compatibility

The single specification that decides fit is the Schedule 40 wall thickness of 0.216 inches. This yields an outside diameter of 3.5 inches and an inside diameter of 3.068 inches. Matching Schedule 40 fittings and threading standards are required for a proper seal. Verify the schedule rating before installation.

Questions about this item

How do I install this 3" MNPT threaded nipple and what step is often missed?

Apply thread sealant to the 3.5" outside diameter MNPT threads and tighten to 150 psi rating, ensuring the continuous weld stays aligned — skipping sealant causes leaks at the 3.068" inside diameter bore.

What maintenance or replacement will this galvanized steel nipple need over time?

Inspect the .216" wall thickness annually for internal corrosion at the 3.068" bore; replace if galvanizing wears through or if ASTM A53 Type F Grade A weld shows pitting under 150 psi @ 150°F service.

What limit appears first when this Sch 40 nipple runs continuously at max pressure and temperature?

The 150 psi @ 150°F rating is the first limit; sustained operation at this level stresses the .216" wall and continuous weld before the 3.068" inside diameter flow capacity becomes restrictive.
