Malleable Iron Reducing Tee Class 150

This Zoro Select fitting connects three pipes with female NPT threads in a 1-1/4 by 1-1/4 by 1 inch configuration. It is manufactured from ASTM A47 and A197 malleable iron with an electro-galvanised gold finish. The tee meets ASME B16.3 and B16.4 dimensional standards and carries FM and UL listings for fire protection and general service applications.

Pressure and temperature limits for Class 150

The fitting handles a maximum pressure of 300 psi at 150 degrees Fahrenheit and a saturated steam pressure of 150 psi. Its operating temperature range spans from minus 20 degrees to 366 degrees Fahrenheit. These ratings define the safe envelope for water, oil, air and steam lines; exceeding them risks joint failure or leakage.

Installation notes and common issues

Thread sealant or tape must be applied to the FNPT connections before assembly to ensure a leak-free seal. Over-tightening can crack the malleable iron casting, particularly on the smaller 1 inch branch. Misaligned piping induces stress that may cause leaks at the threads over time. The gold coating resists corrosion but should be inspected if exposed to harsh chemicals.

Questions about this item

Should I pick the 1-1/4 x 1-1/4 x 1 in reducing tee or a different size for my piping layout?

Choose this tee when you need to branch a 1 in line off a 1-1/4 in header; the three FNPT ports are fixed at those diameters, so match them to your pipe schedule.

What does the Class 150 / 300 psi @ 150 °F rating mean once the tee is installed in my system?

It sets the maximum non-shock working pressure at 300 psi for temperatures up to 150 °F; above that temperature the allowable pressure drops along the Class 150 curve.

How do the ASME B16.3 and B16.4 standards and FNPT threads limit what I can connect to this fitting?

The standards govern the malleable iron dimensions and Class 150 pressure-temperature envelope; FNPT threads require matching taper-threaded pipe or nipples for a seal.
