Black forged steel pipe bushing with threaded ends

Value Brand

Value Brand 1MNK3 Black Forged Steel Bushing Class 3000

SKU CH-W6HN-HT88G

Black forged steel bushing with NPT threads connects 1 1/4 in to 1 in pipe at 3000 psi

  • Forged steel construction delivers 3000 psi pressure rating
  • NPT threaded connection ensures leak-free joint integrity
  • ANSI B1.20.1 and ASME B16.11 compliance guarantees dimensional accuracy
  • ASTM A105 material certification confirms high-temperature suitability
  • Class 3000 rating supports demanding industrial applications

Forged Steel Bushing 3000 Class

This Value Brand 1MNK3 bushing is a black forged steel pipe fitting built to Class 3000 pressure rating. It connects a 1 1/4 inch NPT male thread to a 1 inch NPT female thread. The component meets ANSI B1.20.1, ASME B16.11 and SA105, and ASTM A105 standards for industrial piping systems.

Replaces Welded Reducers

Use this bushing instead of a welded reducing coupling when a removable, threaded joint is required. The jump is worth it for maintenance access, vibration-prone lines, or when hot-work permits are unavailable. It is not for systems requiring a full-bore flow path or for joining dissimilar pipe schedules beyond the rated class.

Sustained Pressure Performance

Rated for 3000 psi at 72 degrees Fahrenheit, the forged steel body maintains structural integrity under continuous operating pressure. The NPT taper threads seal through metal-to-metal engagement without relying on gaskets that degrade over time. It is not for applications exceeding the Class 3000 pressure-temperature envelope or for highly erosive media that accelerate thread wear.

Questions about this item

Will the 1 1/4 in x 1 in NPT threads match my existing pipe?

The bushing has a 1 1/4 in x 1 in NPT connection that follows ANSI B 1.20.1 threading, so it will mate with any pipe or fitting cut to the same NPT standard.

What is the correct way to seal the NPT threads without cracking the forged steel?

Apply PTFE tape or pipe dope to the male threads only, then hand-tighten and finish with one to two full turns using a wrench; over-torquing can split the Class 3000 forged steel body.

When should I plan to replace this Class 3000 bushing in a standard water system?

Inspect annually for corrosion or thread deformation; replace if you see leaks, visible pitting, or after any pressure event that exceeds the 3000 psi @ 72 °F rating.
