Galvanized steel pipe nipple, threaded both ends, silver-grey finish

Value Brand

Value Brand 1-1/2" MNPT x 12" TBE Galvanized Steel Pipe Nipple Sch 40

SKU CH-VGDS-PS0TH

A 12-inch galvanized steel nipple with 1-1/2 inch MNPT threads for air, gases and potable water at 300 psi

  • 1-1/2 in nominal size fits standard Schedule 40 piping
  • 12 in overall length suits common installation spacing
  • Galvanized steel finish resists corrosion in wet environments
  • Rated 300 psi at 150 °F for air, gas and potable water
  • Electric resistance welded construction ensures leak-free joints

Application & Suitability

This galvanized steel pipe nipple fits Schedule 40 systems requiring a 1-1/2 inch nominal size and 12 inch overall length. It handles air, gases and potable water at a maximum operating pressure of 300 psi at 150 degrees F. The threaded both ends design suits standard NPT connections in residential or commercial plumbing.

Pressure & Temperature Limits

Rated for 300 psi at 150 degrees F for water, air and gas service and 150 psi at 350 degrees F for steam. The galvanized coating provides corrosion resistance in normal indoor and outdoor environments. Electric resistance welded construction maintains joint integrity under these pressure and temperature conditions.

Upgrade Considerations

This nipple replaces a damaged or corroded Schedule 40 section of the same nominal diameter and length. The jump is warranted when the existing fitting shows thread wear, rust penetration or leakage at the weld seam. It is not suited for systems requiring higher pressure ratings, different nominal sizes or non-threaded connection types.

Questions about this item

How do I install the 1-1/2" MNPT nipple without cracking the Schedule 40 galvanized threads?

Wrap the male NPT threads with PTFE tape or pipe dope, then hand-tighten into the female fitting before using a pipe wrench for one to two additional turns; the step many miss is stopping before the joint bottoms out, which can split the Schedule 40 wall.

Will the galvanized coating on this 12-inch nipple need replacement, and how can I tell?

The zinc coating is sacrificial and cannot be reapplied in place; plan to replace the nipple when you see white rust spreading, red rust appearing at the threads, or if water tests show elevated zinc levels.

What pressure or temperature limit will I hit first if I run 150 °F water continuously through this Schedule 40 steel nipple?

The 300 psi rating at 150 °F is the governing limit; steam service is rated lower at 150 psi @ 350 °F, so hot-water pressure is the first boundary you reach.
