Value Brand 5P501 Malleable Iron Reducing Tee

SKU CH-W978-Y771B

Malleable iron reducing tee connects three pipe sections at 1-1/4 by 1-1/4 by 1/2 inches with FNPT threads, rated to 300 psi and 366 degrees Fahrenheit

  • Reduces flow from 1-1/4" to 1/2" branch
  • Malleable iron withstands 300 psi at 150 °F
  • FM Approved and UL Listed for code compliance
  • Meets ASME B16.3, B16.4 and ASTM A197, A47
  • Operates from -20 °F to 366 °F for steam lines

Fitting For Pressurised Water And Steam Systems

This malleable iron reducing tee connects three pipe runs at a 1 1/4 by 1 1/4 by 1/2 inch FNPT junction. It meets ASME B16.3 and B16.4 standards plus ASTM A197 and A47 specifications. The fitting carries FM approval and UL listing for fire protection and general service use. It suits installers needing a durable branch connection in commercial or industrial piping.

Rated For Continuous Service Up To 366 Degrees F

The Class 150 body handles a maximum pressure of 300 psi at 150 degrees Fahrenheit and 150 psi saturated steam pressure. The temperature range extends from minus 20 to 366 degrees Fahrenheit without derating. Malleable iron construction resists shock and vibration better than cast iron under cyclic thermal loads. Performance stays consistent across the full rated envelope rather than peaking only in short bursts.

Simple Threaded Assembly With Standard Pipe Tools

Installation uses ordinary pipe wrenches and thread sealant on the FNPT ends. The reducing branch requires correct orientation so the 1/2 inch outlet aligns with the planned pipe run. Over tightening can crack the iron body because the material does not yield like steel. Leaks usually come from insufficient sealant or damaged threads rather than the fitting itself.

Questions about this item

How much heat can the malleable iron reducing tee handle during continuous operation?

The tee operates from -20 to 366 degrees Fahrenheit and handles saturated steam at 150 psi, so it tolerates prolonged high-temperature service.

What pipe threads must the installer already have to connect this reducing tee?

The fitting uses FNPT threads in 1-1/4 inch by 1-1/4 inch by 1/2 inch sizes, so matching NPT male threads are required on all three pipes.

Will this Class 150 tee mate with older ASME B16.3 piping already in the building?

Yes, it meets ASME B16.3 and B16.4 standards, so it threads onto existing Class 150 malleable iron pipe of the same nominal sizes.
