Anvil 1" Malleable Iron Tee Trap

This Anvil 0310516406 is a Class 300 malleable iron tee designed for Schedule 80 piping systems. It provides three 1-inch female NPT connections for branching drain or trap lines in plumbing installations. The fitting suits contractors and maintenance teams needing a durable junction rated for high-pressure service.

Upgrading from lower-class fittings

Replacing a Class 150 or standard-weight tee with this Class 300 component is worthwhile when the system operates near 2,000 psi at 150 degrees Fahrenheit. The jump is justified for Schedule 80 networks where thinner-walled fittings would not meet pressure requirements. It is not for low-pressure residential drainage or systems using Schedule 40 pipe.

Installing the tee trap

Installation requires threading the three female NPT ports onto matching male pipe ends with appropriate sealant. The heavy malleable iron body demands proper alignment and support to avoid stress on joints during tightening. What usually goes wrong is cross-threading the NPT ports or using insufficient pipe dope, which can lead to leaks at the rated pressure.

Questions about this item

What pipe size and thread type does the 1" malleable iron tee require?

The tee has three 1 inch female NPT connections for Schedule 80 pipe.

How is the Class 300 tee installed, and what step is often missed?

Thread each end onto Schedule 80 pipe with sealant, tightening to the Class 300 rating; the step often missed is confirming the 2,000 psi at 150 °F pressure limit before pressurising.

What maintenance or replacement will the malleable iron tee need over time?

Inspect threads and sealant periodically for corrosion or leaks; replace the tee if cracking or thread damage appears under the 2,000 psi at 150 °F service conditions.
