Value Brand 6P808 3/4" MNPT x 3" TBE Galvanized Steel Pipe Nipple Sch 40

SKU CH-XVW3-JX7YX

Galvanized steel pipe nipple with 3/4 inch MNPT threads and 3 inch length for air, gas or potable water systems rated to 300 psi

  • Corrosion-resistant galvanized coating extends service life in wet environments
  • 300 psi pressure rating handles demanding air and gas lines
  • Welded steel construction provides structural strength for permanent installs
  • Schedule 40 wall thickness fits standard plumbing systems
  • 150 psi steam rating supports high-temperature applications

3/4" Schedule 40 galvanised nipple

This 3-inch pipe nipple is manufactured from welded galvanised steel and carries a 3/4-inch nominal pipe size with male NPT threads on both ends. It is designed for air, gas and potable water distribution in residential or light commercial plumbing systems.

Pressure rating under continuous use

The fitting withstands a maximum operating pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi at 350 degrees Fahrenheit. These limits apply to sustained service rather than momentary spikes, so the component remains within specification during extended duty cycles.

Welded construction and galvanised finish

Electric resistance welding creates a consistent seam along the pipe body, while the galvanised coating provides corrosion resistance for wet or humid environments. The Schedule 40 wall thickness and 1 3/64-inch outside diameter allow direct threading into standard Schedule 40 fittings without adapters.

Questions about this item

Does the 300 psi rating at 150 degrees F affect heat buildup during all-day water service?

The nipple is rated for 300 psi at 150 degrees F and 150 psi steam at 350 degrees F, so it handles continuous hot-water or steam lines without extra heat generation.

What mating fittings are needed to install this 3/4 inch MNPT nipple?

It requires a 3/4 inch female NPT fitting on each end; any Schedule 40 galvanized or black-iron coupling, elbow or valve with matching threads will thread directly onto the nipple.

Will this Schedule 40 galvanized nipple thread onto existing black-iron pipe of the same nominal size?

Yes, the 3/4 inch NPT threads are cut to the same standard, so it joins directly to legacy black-iron or galvanized pipe without adapters.
