Anvil 387 2 in Hex Head Plug
The Anvil 387 is a 2 in nominal pipe size hex head plug made from galvanized malleable iron. It carries a Class 150 rating and male NPT threads for standard piping connections. The solid construction suits residential and light commercial plumbing installations.
Verify thread type and pressure rating
Confirm the mating fitting uses male NPT threads before ordering. The plug is rated for 300 psi maximum operating pressure at 150 degrees Fahrenheit. Operating temperature range spans -20 degrees to 350 degrees Fahrenheit for the intended service.
Galvanized finish resists corrosion
The galvanized coating protects the malleable iron body against rust in water and air lines. No pre-applied thread sealant or seal is included, so apply compatible tape or compound during assembly. Solid plug design eliminates internal flow paths that could trap debris.

Questions about this item
Does the Anvil 387 hex head plug come with thread sealant or a sealing washer already applied?
The plug is supplied without pre-applied thread sealant and without an included seal, so separate pipe thread compound or tape must be provided by the installer.
What pressure and temperature limits define the Class 150 rating on this 2 in malleable iron plug?
Class 150 corresponds to a maximum operating pressure of 300 psi at 150 degrees F, with an overall service range from minus 20 degrees F to 350 degrees F.
Will the 300 psi rating hold at the top of the temperature range when the plug is installed in a steam line?
At 350 degrees F the allowable pressure is lower than 300 psi; the 300 psi figure applies only at 150 degrees F, so steam-service pressure must be derated according to the applicable piping code.
