  • 1/4-inch FNPT tee fits standard plumbing threads
  • Malleable iron body withstands 300 psi at 150 °F
  • UL listed and FM approved for code compliance
  • Meets ASME B16.3 dimensional standard
  • Rated for saturated steam up to 150 psi

Anvil Malleable Iron Tee

The Anvil 0310029400 tee connects three 1/4 inch FNPT threads in a malleable iron body rated for Class 150 service. It suits plumbing installers and maintenance crews who need a durable branch fitting for water, oil or air lines. The UL Listed and FM Approved design meets ASME B16.3 standards for reliable performance in commercial and industrial piping systems.

Thermals and pressure limits

The fitting handles saturated steam pressure up to 150 psi and a maximum pressure of 300 psi at 150 degrees Fahrenheit. Its temperature range spans from minus 20 degrees to 150 degrees Fahrenheit, so it remains stable in both chilled-water and low-pressure steam circuits. Malleable iron construction resists mechanical shock and vibration without deformation under normal operating conditions.

Upgrade path and fit

This tee replaces worn or corroded 1/4 inch threaded tees in existing Class 150 networks where UL or FM approval is required. The jump is worth it when a fitting must satisfy both standards simultaneously or when the installer needs the broader temperature envelope up to 150 degrees Fahrenheit. It does not suit systems requiring larger pipe diameters or higher pressure classes beyond the stated ratings.

Questions about this item

How do I install this 1/4" FNPT malleable iron tee without cracking the body?

Clean threads, apply PTFE tape or pipe dope to male ends only, hand-tighten then turn one to two full turns with a wrench on the tee flats — never use the branches as leverage points.

What maintenance or replacement will this Class 150 tee need over time?

Inspect yearly for external corrosion, thread galling or weeping at joints; replace if cracks appear or if system pressure exceeds the 300 psi at 150 °F rating.

What is the first limit reached under sustained high-temperature steam service?

Saturated steam pressure is rated at 150 psi; exceeding this before the 300 psi water-pressure limit will require immediate pressure reduction or tee replacement.
