2 in Class 3000 Stainless Steel Plug

This Value Brand square head plug is made from 304 stainless steel for corrosion resistance and durability in fluid or gas transfer systems. It is rated for Class 3000 service and features a male NPT thread for connecting to female threaded ports. The fitting suits installers who need a reliable pipe closure in demanding environments.

Installation and common issues

The square head allows tightening with a standard wrench for straightforward installation into a matching female NPT thread. Applying appropriate thread sealant or tape helps prevent leaks at the joint. Over-tightening can damage threads or crack the fitting, while under-tightening may leave a weep path. Always verify the mating thread size before assembly.

Class 3000 pressure boundary

Class 3000 defines the pressure-temperature rating envelope for this forged stainless steel fitting. The rating decreases as system temperature rises, so the maximum allowable pressure at operating temperature must be confirmed against the relevant piping code. The 304 stainless material resists many corrosive media but is not suitable for all chemical services. This plug cannot join pipes of different diameters.

Questions about this item

How can I confirm the plug is sealing correctly after installation?

Pressurise the system to its rated Class 3000 limit and check the 2 in MNPT threads for any leakage; the 304 stainless steel material should show no weeping at the square head joint.

Which class and alloy should I select for my piping?

Choose this Class 3000 304 stainless steel version when the system requires that pressure rating and corrosion resistance; other classes or alloys are separate listings.
