Anvil 3-Inch Cast Iron FNPT Tee

The Anvil 0300033008 is a 3-inch cast iron tee with female NPT threads on all three ports. It is built to Class 125 specifications for plumbing and piping systems requiring a durable branch connection. The fitting carries UL listing and FM approval, and it meets the ASME B16.4 standard for cast iron threaded fittings.

Verify Thread Type and Pressure Rating

Confirm that your existing piping uses FNPT threads compatible with the three female ports on this tee. The fitting is rated for a maximum pressure of 175 psi across a temperature range of -20 to 150 degrees Fahrenheit. Saturated steam service is limited to 125 psi, so check that your system design stays within these limits before installation.

Sustained Load Behaviour Under Pressure

Under continuous operating pressure up to 175 psi the cast iron body maintains its structural integrity throughout the rated temperature span. The Class 125 wall thickness resists deformation during prolonged steam exposure at 125 psi, and the threaded joints hold seal without relaxation when the system cycles between the stated temperature extremes.

Questions about this item

What comes in the box and do I need to buy any gaskets or pipe sealant separately?

The box contains one cast iron tee with three 3 inch FNPT ports rated Class 125. Gaskets, thread sealant and pipe nipples are not included and must be purchased separately if required for your installation.

The listing shows only one 3 inch Class 125 version — how do I confirm it matches my pressure and temperature needs?

This fitting is rated for 175 psi at temperatures from -20 to 150 degrees F and 125 psi saturated steam, meeting ASME B16.4 with UL and FM approvals. Choose it when your system operates within those limits.

What does the 175 psi rating mean once the tee is threaded into a working piping system?

It means the tee can safely handle up to 175 psi continuous pressure at temperatures between -20 and 150 degrees F, provided the mating threads are properly sealed and the pipe schedule matches the Class 125 design.
