Malleable Iron Class 300 Coupling

The Anvil 0310539200 coupling connects two sections of Schedule 80 pipe using 1 1/2 inch female NPT threads on both ends. It is rated for a maximum operating pressure of 500 psi at 150 degrees Fahrenheit. This component suits installers needing a strong, threaded joint in high-pressure drain or piping systems.

Verify Pipe Schedule and Thread Type

Confirm that the existing pipe is Schedule 80 and uses 1 1/2 inch male NPT threads before ordering. The Class 300 rating and 500 psi pressure limit at 150 degrees Fahrenheit must match the system design requirements. Mismatched schedules or thread standards will prevent a proper seal and could cause failure under pressure.

Malleable Iron Construction for Durability

The malleable iron body resists cracking and deformation under mechanical stress and thermal cycling up to 150 degrees Fahrenheit. Female NPT threads on both ends allow direct connection to male-threaded pipe or fittings without additional adapters. This design supports reliable, leak-free joints in demanding drain and trap installations.

Questions about this item

What does the Anvil 0310539200 coupling include and is anything else required for installation?

The box contains the malleable iron coupling with 1 1/2 in female NPT threads on both ends. Pipe, thread sealant and tools are not included and must be sourced separately.

Which class and schedule rating should I select for my system?

Choose this Class 300 coupling when your piping is Schedule 80 and the design pressure does not exceed 500 psi at 150 degrees F.

What does the 500 psi at 150 degrees F rating mean in actual service?

It is the maximum continuous operating pressure the coupling can handle at that temperature; pressure must be reduced if the system runs hotter.
