Galvanized steel pipe nipple with threaded ends

Value Brand

Value Brand 4" MNPT x 8" TBE Galvanized Steel Pipe Nipple Sch 40

SKU CH-R78D-WXD62

Threaded 4-inch galvanized steel pipe nipple, 8 inches long, Schedule 40, rated to 500 psi

  • Threaded both ends for quick, leak-resistant assembly
  • Schedule 40 wall rated to 500 psi for high-pressure systems
  • Hot-dip galvanised steel resists corrosion in wet environments
  • Electric-resistance welded seam meets ASTM A-53 Type E and A-733 Grade B
  • Metal-detectable construction aids line tracing and inspection

4 in Sch 40 Galvanized Nipple

This 4 in nominal Schedule 40 galvanized steel pipe nipple is built for threaded plumbing assemblies. It serves installers who need a straight 8 in connector with male NPT threads on both ends for water, air or gas distribution systems.

Welded Construction Rated to 500 psi

Electric resistance welded seams and a hot-dip galvanized coating give the nipple a 500 psi maximum pressure rating. The welded Schedule 40 wall maintains integrity under sustained system pressure without the deformation risk that can appear in lighter-wall alternatives.

Replaces Shorter or Lower-Rated Nipples

The 8 in overall length spans gaps that shorter nipples cannot bridge, while the Schedule 40 wall and 500 psi rating step up from lighter-duty fittings. The jump is worth it when the installation demands both the extra reach and the higher pressure margin in a single threaded component.

Questions about this item

Does the 500 psi rating hold up when water runs through the 4 in Schedule 40 nipple all day?

The nipple is rated for 500 psi maximum pressure and meets ASTM A-53 Type E and ASTM A-733 Grade B, so continuous flow at design pressure is within its specification.

What thread sealant or tape do I need for the MNPT ends on this 4 in galvanized nipple?

Both ends are MNPT threads; apply PTFE tape or pipe-joint compound rated for potable water and 500 psi service before tightening into the mating fittings.

Will this 8 in nipple thread directly into my existing 4 in NPT fittings?

Yes, each end is cut to MNPT per the WWN 351 standard, so it mates with any 4 in NPT female fitting without adapters.
