Value Brand

Value Brand 1-1/2" MNPT x 4" TBE Galvanized Steel Pipe Nipple Sch 40

SKU CH-ZJKV-V1GED

Galvanised steel pipe nipple with 1-1/2 inch MNPT threads and 4 inch overall length for Schedule 40 systems rated to 300 psi at 150 degrees F

  • Corrosion-resistant galvanized coating protects against rust
  • Schedule 40 steel handles 300 psi at 150°F
  • Suitable for air, gases and potable water systems
  • Electric resistance welded construction ensures leak-free joints
  • California Proposition 65 warning for chemical exposure risk

Threaded Steel Nipple for Air and Water

The Value Brand Schedule 40 pipe nipple connects air, gas or potable water lines using 1-1/2 inch male NPT threads on a 4 inch overall length. The galvanized steel body resists corrosion in standard plumbing and compressed-air installations. It is manufactured to Schedule 40 wall thickness for compatibility with matching fittings.

Pressure Rating and Welded Construction

The nipple withstands 300 psi at 150 degrees F for water, oil or air service and 150 psi at 350 degrees F for saturated steam. Electric-resistance welding produces a consistent seam along the 1 57/64 inch outside diameter. Galvanized coating adds surface protection without changing the pressure limits.

California Proposition 65 Notice

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. The warning applies to the galvanized finish and base steel. No additional sealant, gasket or software is supplied with the fitting.

Questions about this item

How do I install the 1-1/2" MNPT threaded ends on Schedule 40 pipe, and what step is often missed?

Apply PTFE tape or pipe dope to the male NPT threads, then tighten with a pipe wrench on the hex flats. The step often missed is cleaning both threads thoroughly before sealing to prevent leaks.

What maintenance or replacement will the galvanized coating need over time?

The galvanized finish resists corrosion but can wear at thread roots or where water sits. Inspect annually for white rust or pitting; replace the nipple if wall thickness is reduced or leaks appear at the weld seam.

What pressure or temperature limit will be reached first during continuous hot-water circulation at 300 psi?

The 150 psi steam rating at 350 °F is lower than the 300 psi water rating at 150 °F, so the steam limit governs if the system ever flashes to steam. Stay below 150 psi when temperatures approach 350 °F.
