  • Forged steel construction withstands 1500 psi at 150 °F
  • Class 3000 rating supports 300 psi saturated steam at 550 °F
  • FNPT threads meet ASME B 16.11 and ASTM A106 standards
  • Black finish protects against corrosion in temperatures from -20 to 550 °F
  • Reduces 1 1/4 in to 3/4 in pipe with 2 1/4 in outside diameter

Pipe reducer for high-pressure systems

The Anvil 0361176902 is a black forged steel reducer built to Class 3000 specifications for demanding piping installations. It connects a 1 1/4 in pipe to a 3/4 in pipe using FNPT threaded ends and meets ASME B 16.11 and ASTM A106 standards.

Suits installers needing Class 3000 forged steel

This fitting serves engineers and plumbers assembling systems rated for 1500 psi at 150 Degrees F or 300 psi saturated steam at 550 Degrees F. It is not for buyers who need welded connections, a different pressure class, or a fitting made from stainless steel or other alloys.

Verify thread standard and temperature limits

Confirm that your piping uses B 1.20.1 FNPT threads and that the operating range stays within -20 Degrees to 550 Degrees F. Check that the 2 1/4 in outside diameter and two-hole pattern match the available space and the mating components in your assembly.

Questions about this item

What pipe sizes must I already have to thread this 1 1/4 in x 3/4 in FNPT reducer?

You need a 1 1/4 inch FNPT female pipe and a 3/4 inch FNPT female pipe — both tapered NPT threads matching the ASME B1.20.1 standard.

Will this Class 3000 forged steel reducer hold up on a line that also has older Class 150 fittings?

Yes — it is rated 1500 psi at 150 °F and 300 psi saturated steam at 550 °F, well above Class 150 limits, so it will not be the weak point.

How can I confirm the reducer is seated correctly after assembly?

Check that both NPT threads are fully engaged with no visible gaps, then pressure-test the joint up to the system’s working pressure — no leaks means it is seated.
