Anvil Malleable Iron Coupling Class 300

This Anvil malleable iron coupling is a Class 300 drain component built for 1 in NPT female threads. It suits plumbers and maintenance teams joining Schedule 80 pipe in water, oil or gas lines where a strong threaded joint is required.

Class 300 pressure rating

The coupling carries a Class 300 rating with a maximum operating pressure of 2 000 psi at 150 degrees F. That single figure decides whether the fitting matches the design pressure of the system you are assembling.

Schedule 80 pipe compatibility

It comfortably handles Schedule 80 pipe at the rated pressure and temperature. It runs out if the system exceeds 2 000 psi or 150 degrees F, or if the piping schedule or thread standard differs from the stated NPT 1 in female configuration.

Questions about this item

What does the Class 300 rating mean for everyday plumbing use?

Class 300 indicates the coupling is rated for 2,000 psi at 150 degrees F, making it suitable for high-pressure Schedule 80 piping systems.

How does the NPT threading affect compatibility with other fittings?

The 1-inch female NPT threads on both ends accept standard male NPT pipe or nipples, creating a tapered seal without additional adapters.

What clearance is needed to install this malleable iron coupling?

The coupling connects two 1-inch female NPT ends directly, so you need enough space to thread both pipes into the fitting without obstruction.
