Anvil 3" Forged Steel Square Head Plug

This Anvil square head plug is a forged steel fitting designed to close a 3 inch male NPT pipe end. It provides a dependable seal for water or gas pipelines in plumbing installations. The Class 3000 rating supports a maximum pressure of 1000 psi at 150 degrees Fahrenheit.

Questions about this item

Will the forged-steel square-head plug need periodic replacement under normal service?

The Class 3000 forged steel body is rated for 1000 psi at 150°F and does not carry a scheduled replacement interval; inspect threads and sealing surfaces during routine system maintenance.

What pressure or temperature limit will be reached first during continuous operation?

The fitting is rated to 1000 psi at 150°F; exceeding either the pressure or the temperature rating first will breach the Class 3000 design limits.

Does the plug generate heat or noise when the system runs all day?

As a passive threaded plug it produces no noise or heat of its own; any temperature rise comes from the fluid inside the pipe.
