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

Value Brand

Value Brand 1-1/2" MNPT x 8" TBE Galvanized Steel Pipe Nipple Sch 40

SKU CH-DQZX-7RVSV

Galvanised steel pipe nipple with 1-1/2" male NPT threads and 8" overall length for air, gas or potable water systems rated to 300 psi at 150 °F

  • Galvanized coating resists corrosion for longer service life
  • Schedule 40 wall handles 300 psi at 150 °F
  • Electric resistance weld gives consistent joint strength
  • 1-1/2 inch NPT threads fit standard Schedule 40 fittings
  • Suitable for air, gases and potable water systems

Application Range

This galvanized steel pipe nipple suits air, gas and potable water lines in residential and light commercial plumbing. The Schedule 40 rating and 300 psi pressure limit at 150 degrees Fahrenheit match standard municipal supply requirements. Electric resistance welded construction provides consistent wall thickness for reliable sealing. California Proposition 65 warnings apply due to chemical content.

Thermal and Pressure Performance

The fitting handles continuous water pressure up to 300 psi at 150 degrees Fahrenheit and saturated steam up to 150 psi at 350 degrees Fahrenheit. Galvanized coating resists corrosion from moisture and mineral exposure in typical indoor installations. Welded seam integrity remains stable across the rated temperature span without additional joint compounds. No moving parts mean silent operation under flow.

Upgrade Context

This nipple replaces corroded or damaged threaded sections in existing Schedule 40 steel piping without changing pipe diameter or fitting class. The 8 inch overall length and 1 57/64 inch outside diameter fit standard 1 1/2 inch nominal connections. It is not suited for systems requiring higher pressure classes, stainless steel compatibility or non-threaded joining methods.

Highlights

  • Schedule 40 wall handles 300 psi at 150 °F
  • Electric resistance weld gives consistent joint strength

Questions about this item

How do I install this 1-1/2" MNPT galvanized nipple without damaging the threads?

Apply PTFE tape or pipe dope to the male NPT threads only, then hand-tighten before finishing with a wrench — overtightening cracks the Schedule 40 wall.

What maintenance will this steel nipple need over its service life?

Inspect the galvanized coating annually for white rust or pitting; replace the nipple if corrosion penetrates to the base steel.

At what temperature does the 300 psi pressure rating start to drop?

The 300 psi rating holds to 150 °F; above that temperature the allowable working pressure decreases.
