Anvil 0310009006 90 Degree Reducing Elbow Class 150 Malleable Iron 1 1/4 x 1 FNPT

SKU CH-RS81-M3DH4 MPN 0310009006

A 90-degree reducing elbow connects 1 1/4-inch and 1-inch FNPT pipes with Class 150 malleable iron rated for 300 psi at 150 degrees F

  • TypeDrain Components
  • Connects 1 1/4 in to 1 in FNPT pipes for versatile installations
  • Rated 300 psi at 150 °F for reliable high-pressure service
  • Handles saturated steam at 150 psi and 350 °F for demanding thermal applications
  • Operates from -20 °F to 350 °F across wide temperature ranges
  • Meets ASME B16.3 and UL/FM standards for code-compliant installations

Malleable Iron 90 Degree Reducing Elbow Class 150

This Anvil 0310009006 fitting connects 1 1/4 inch and 1 inch FNPT threads at a 90 degree angle. It is made from black malleable iron rated for Class 150 service. The component meets ASME B 16.3 standards and carries UL and FM approvals. It suits plumbing and piping systems requiring a durable, threaded direction change.

For installers joining dissimilar pipe sizes

The reducing elbow fits systems using 1 1/4 inch and 1 inch FNPT connections within the stated pressure and temperature limits. It is not for applications needing a straight reducer, a tee, or a coupling without a directional change. Installers requiring a different thread type or a fitting not approved to ASME B 16.3 should select another part.

Class 150 pressure rating up to 300 psi at 150

This single specification defines the fitting's safe operating envelope for water, oil, or gas service. Saturated steam pressure is rated at 150 psi at 350 Degrees F with a temperature range from -20 Degrees to 350 Degrees F. Verify your system design against these limits before installation.

Questions about this item

Should I choose the 1 1/4 x 1 in reducing elbow or a straight coupling for my pipe transition?

Choose the 90 degree reducing elbow when you need to change direction and step down from 1 1/4 in to 1 in pipe in one fitting; use a straight coupling only if the run stays linear.

What does the Class 150 rating mean once the fitting is installed in a steam system?

Class 150 limits saturated steam service to 150 psi at 350 Degrees F, so the fitting is rated for low-pressure steam lines within that temperature ceiling.

How do the FNPT threads and ASME B 16.3 standard affect what pipe I can connect?

The female NPT threads accept 1 1/4 in and 1 in male NPT pipe ends, and ASME B 16.3 confirms the malleable iron dimensions and 300 psi at 150 Degrees F pressure rating.
