Anvil 1in x 3/4in Reducing Tee

This Anvil malleable iron reducing tee connects three female NPT pipes at 1in, 1in and 3/4in. It is rated Class 300 for use with Schedule 80 piping systems. The fitting handles a maximum operating pressure of 2,000 psi at 150 degrees F. Plumbers and pipefitters specify it for high-pressure water, steam, oil or gas distribution.

Suited for Schedule 80 high-pressure lines

Installers building or repairing Class 300 systems with 1in and 3/4in NPT branches will find the correct end sizes here. The reducing layout lets a 3/4in line join a 1in header without extra bushings. Projects using thinner wall pipe or lower pressure ratings cannot use this fitting. Applications requiring welded, flanged or grooved connections need a different component.

Class 300 pressure rating decides fit

The 2,000 psi at 150 degrees F rating is the single figure that determines whether this tee matches the system design. If the piping specification calls for Class 300 and Schedule 80, the part fits. If the design uses a lower class or thinner schedule, the rating is excessive and the fitting will not seal correctly. Always verify the engineering specification before ordering.

Questions about this item

How is the Anvil 0310521208 reducing tee installed, and what step is often missed?

Thread each female NPT connection onto Schedule 80 pipe using suitable sealant; the step often missed is confirming the 300 Class rating matches the system pressure before tightening.

What maintenance or replacement will the malleable iron tee need later?

Inspect threads and sealing surfaces periodically for corrosion or leakage; replace the tee if cracks, heavy scaling or thread deformation appear during routine system checks.

What limit appears first under sustained use at the rated 2,000 psi and 150 Degrees F?

The 300 Class pressure-temperature ceiling is the first limit; sustained operation at the maximum 2,000 psi and 150 Degrees F leaves no margin for pressure spikes or temperature rise.
