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

SKU CH-9W95-STBJW

Malleable iron reducer coupling connects 2-1/2 inch to 2 inch FNPT pipes, rated Class 300 for 1000 psi at 150 degrees F and 300 psi saturated steam from -20 to 550 degrees F, meeting ASME B16.3.

  • Malleable iron construction resists cracking under stress
  • Class 300 rating handles 1000 psi at 150°F
  • FM Approved and UL Listed for code compliance
  • ASME B16.3 and B16.4 standards ensure dimensional accuracy
  • Operates from -20°F to 550°F for steam and water lines

Industrial Plumbing Reducer

This malleable iron reducer coupling connects a 2-1/2 inch pipe to a 2 inch pipe in industrial plumbing systems. It is built to ASME B 16.3 and B 16.4 standards for reliable service in demanding environments. The fitting suits engineers and maintenance crews managing high-pressure steam or fluid lines. It is not for installers needing a straight coupling or a different material such as brass or plastic.

Class 300 Threaded Integration

The fitting uses FNPT threads to join directly to matching pipe ends without welding or soldering. Its Class 300 rating supports a maximum pressure of 1000 psi at 150 degrees F and saturated steam pressure up to 300 psi. The malleable iron construction handles a temperature range from -20 degrees to 550 degrees F. Builders requiring a socket-weld or flanged connection must source a different fitting type.

Certified Safety Compliance

FM Approved and UL Listed certifications confirm the coupling meets recognised safety benchmarks for fire protection and general industrial use. Compliance with ASTM A-197 and ASTM A47 guarantees the material quality of the iron casting. These approvals simplify specification for code-driven projects and insurance requirements. The coupling includes no gaskets, sealant or installation tools in the package.

Questions about this item

What is the maximum sustained pressure this Class 300 malleable iron reducer can handle at 150 °F?

The fitting is rated for 1000 psi at 150 °F, which is the limit that governs continuous liquid service.

How hot does the coupling get when carrying saturated steam at its 300 psi rating?

Saturated steam at 300 psi operates within the fitting’s -20 °F to 550 °F temperature range, so the body temperature stays inside the approved envelope.

Which pipe threads must the installer provide to connect this FNPT reducer?

You need a 2-1/2 in male NPT pipe on one side and a 2 in male NPT pipe on the other to engage the female threads.
