A dark, threaded malleable iron reducer coupling with two different sized female ends

Value Brand

Value Brand 2-1/2 x 1-1/4 Malleable Iron Reducer Coupling

SKU CH-38CT-VD3DE

Connects 2-1/2 inch and 1-1/4 inch FNPT pipes with Class 150 malleable iron rated to 300 psi

  • Malleable iron construction resists cracking under pressure
  • Class 150 rating handles 300 psi at 150 Degrees F
  • ASME B 16.3 and B 16.4 compliance ensures dimensional accuracy
  • FM Approved and UL Listed for fire protection systems
  • Operates from -20 to 366 Degrees F for steam and water lines

Reducer Coupling for Pipe Systems

The Value Brand malleable iron reducer coupling joins 2-1/2 inch and 1-1/4 inch FNPT threaded pipe. It meets ASME B16.3, B16.4, ASTM A197 and A47 standards with FM and UL listings. The fitting handles 300 psi at 150 degrees F and saturated steam to 150 psi.

Verify Thread Size and Pressure Rating

Confirm both pipe ends use FNPT threads matching the 2-1/2 by 1-1/4 inch dimensions. Ensure system pressure stays within the 300 psi rating at operating temperature. The coupling suits temperatures from -20 to 366 degrees F for steam or fluid service.

Replaces Worn or Mismatched Threaded Fittings

Use this coupling when stepping down pipe diameter in Class 150 malleable iron systems. The upgrade is worth it when existing fittings leak, corrode or lack FM and UL approval. It restores a code-compliant transition without changing pipe material.

Questions about this item

Does the coupling include pipe sealant or do I need to buy thread tape separately?

The fitting is supplied as the malleable iron reducer coupling only; thread sealant or tape must be purchased separately.

Which pressure rating should I use for a steam line versus a cold water line?

For saturated steam the rating is 150 psi; for water or air at 150 °F the rating is 300 psi.

What does the 300 psi @ 150 °F rating mean when the coupling is installed in a hot water system?

It means the joint can safely handle 300 psi continuous pressure as long as the fluid temperature does not exceed 150 °F.
