Cast iron reducing tee, three female threaded ports, rough grey finish

Anvil

Anvil Reducing Tee 3" x 2-1/2" x 3" FNPT Cast Iron

SKU CH-7Y5W-315A9

Cast iron reducing tee connects three FNPT pipes at 3, 2-1/2 and 3 inches, rated to 175 psi and 150 °F, UL listed and FM approved

  • Reduces pipe diameter while maintaining flow
  • 3" x 2-1/2" x 3" FNPT cast iron body
  • Rated 175 psi from -20 to 150 °F
  • UL Listed and FM Approved for safety
  • Meets ASME B16.4 standard for quality

Anvil Class 125 Reducing Tee

The Anvil reducing tee connects three pipe sections in a T configuration with female NPT threads on every outlet. Cast iron construction meets ASME B 16.4 and carries UL and FM approvals for fire-protection and general plumbing systems. It suits installers joining 3-inch and 2-1/2-inch steel or iron pipe in commercial or residential projects.

Temperature range and pressure rating

The fitting handles saturated steam up to 125 psi and cold-water pressure up to 175 psi across a range of 20 below to 150 degrees Fahrenheit. Cast iron provides steady heat dissipation without the expansion noise common in lighter alloys. No external power or active cooling is required for normal operation.

3" x 2-1/2" x 3" FNPT sizing

The tee reduces the branch to 2-1/2 inches while keeping both run ends at 3 inches, so it only fits piping layouts that match those exact nominal sizes. Systems requiring a different branch diameter or a male-threaded outlet cannot use this fitting.

Questions about this item

How do I install the 3" x 2-1/2" x 3" FNPT cast iron reducing tee, and what step is often done incorrectly?

Wrap PTFE tape clockwise on male threads only, then hand-tighten before final turns with a pipe wrench; the common error is over-tightening female ports, which can crack the cast iron body.

What maintenance or replacement will this Class 125 reducing tee need over time?

Inspect threads annually for corrosion or leakage; replace the fitting if you see cracks, heavy scale build-up, or if system pressure tests exceed the 175 psi rating.

What is the first limit reached under sustained use at the rated temperature range?

The 175 psi maximum pressure at 150 °F is the primary limit; sustained steam service must stay at or below 125 psi to avoid exceeding the saturated steam rating.
