Anvil Malleable Iron Union Class 300

This Anvil union is a malleable iron fitting rated Class 300 for Schedule 80 pipe. It connects two sections with 1/4 in female NPT threads on each end. The fitting handles a maximum operating pressure of 2,000 psi at 150 degrees F. It is a new component for industrial piping systems.

Questions about this item

Will this 1/4 in NPT union thread directly onto my existing Schedule 80 pipe without adapters?

Yes, the union has 1/4 in female NPT ends made for Schedule 80 pipe, so it threads straight onto matching pipe threads.

How can I confirm the Class 300 rating is holding after I install it?

Pressurise the system up to 2,000 psi at 150 °F and check for leaks; the joint should hold without weeping at that pressure and temperature.
