Short galvanized steel pipe nipple with threaded ends

Value Brand

Value Brand 1 in MNPT x 3-1/2 in TBE Galvanized Steel Pipe Nipple Sch 40

SKU CH-2W1H-34577

Galvanised steel pipe nipple with 1 in MNPT and TBE ends for air, gases or potable water up to 300 psi

  • Ready for air, gases and potable water systems
  • Galvanized steel resists corrosion in wet environments
  • Rated 300 psi at 150 °F for pressure lines
  • Schedule 40 wall suits standard fittings
  • Electric resistance weld gives consistent joint strength

Galvanized Steel Pipe Nipple 1 in MNPT

This Schedule 40 nipple connects air, gas or potable-water lines with 1 inch male NPT threads on each end. The 3-1/2 inch overall length suits tight plumbing runs where a short coupling is required. Welded steel construction provides the mechanical strength expected in commercial and residential piping systems.

Pressure Rating and Temperature Limits

The fitting handles 300 psi at 150 degrees F for general service and 150 psi at 350 degrees F for saturated steam. Galvanized coating adds corrosion resistance for extended service life in damp environments. These limits define the safe operating envelope for the intended fluid types.

Threaded Ends and Welded Body

Both ends feature MNPT threads for direct engagement with female fittings, valves or equipment ports. Electric resistance weld construction eliminates a potential leak path at the seam. The globally sourced steel meets Schedule 40 wall thickness for compatibility with standard iron pipe size components.

Questions about this item

How do I install the 1 in MNPT threaded end without damaging the galvanized coating?

Apply PTFE tape or pipe-thread sealant to the male NPT threads only, hand-tighten, then turn one to two full turns with a wrench; over-tightening strips the zinc layer and creates leak paths.

What maintenance will the galvanized steel nipple need over its service life?

Inspect the exterior for white rust or pitting annually; if the zinc coating is breached, replace the nipple because the underlying steel will corrode under 300 psi water pressure.

Which pressure limit is reached first during continuous hot-water circulation at 150 °F?

The 300 psi @ 150 °F water rating governs; the 150 psi steam rating applies only when the medium is saturated steam at 350 °F.
