Anvil 1/2" Malleable Iron Square Head Plug

This new Anvil 0318901568 plug is a solid malleable iron fitting designed to close a 1/2 inch MNPT threaded opening in plumbing systems. It meets ASTM A197 standards and suits Schedule 40 or Schedule 80 pipe installations. The black finish indicates standard iron construction without additional coating.

285 psi maximum operating pressure

The plug withstands up to 285 psi, making the pressure rating the primary specification for selecting this part. It operates across a temperature range of -20 Degrees to 350 Degrees F. The square drive style allows installation with a standard wrench. No pre-applied thread sealant is included.

No sealant or seal included

The product ships without pre-applied thread sealant or an integrated seal, so the installer must supply compatible pipe thread compound or tape separately. This means the accessory kit does not change the sealing method; the buyer provides the sealing materials required for the specific application.
