1-1/2" Class 3000 Forged Steel Plug
This 1-1/2 inch MNPT hex head plug is manufactured from black forged steel to ASTM A105 and SA105 standards. It is rated for 3000 psi at 72 degrees Fahrenheit and conforms to ANSI B 1.20.1 and ASME B 16.11 specifications. The solid construction suits industrial piping systems requiring a Class 3000 threaded closure.
Installation uses standard pipe-thread tools
Apply appropriate thread sealant or tape to the MNPT threads before tightening with a wrench on the hex head. Over-tightening can distort the forged steel threads or crack the mating fitting, while insufficient sealant leads to leaks at the rated pressure. Ensure the pipe threads are clean and undamaged before assembly.
Verify system pressure and thread compatibility
Confirm the piping network operates at or below 3000 psi at the service temperature before ordering. The fitting uses male NPT threads per ANSI B 1.20.1, so the receiving port must be a matching female NPT thread of the same nominal size. The material is carbon steel, so it is not suitable for highly corrosive fluids without additional protection.

Questions about this item
How can I confirm the 1-1/2" forged steel plug is sealing correctly after installation?
Pressure-test the joint up to 3000 psi at 72 °F; no leakage at the MNPT threads indicates the solid plug meets ANSI B1.20.1 and ASME B16.11 requirements.
What comes in the box and what must I supply separately?
The box contains only the black forged steel hex head plug; you must provide compatible 1-1/2" NPT pipe, thread sealant or tape, and a wrench sized for the hex head.
Which class and material grade should I select for a 3000 psi steam line?
Choose the Class 3000 forged steel version made to ASTM A105 / SA105; it is rated for 3000 psi at 72 °F and complies with ASME B16.11 for that service.
