Hex Plug 2-1/2" 150 304

This Zoro Select hex plug is a threaded pipe fitting made from 304 stainless steel. It carries a 150 pressure rating and uses a 2-1/2 inch connection size. The heavy pattern construction suits industrial plumbing systems. The part number is 4381032090.

Suitable Uses and Limits

This plug fits pipelines needing a 150-rated stainless steel closure with a hex head. It is not for systems requiring a higher pressure class or a different material grade. Buyers needing a larger or smaller nominal size must select another fitting. The thread form is specific to this heavy pattern.

Deciding Specification

The 150 pressure rating combined with 304 stainless steel material determines if this plug matches the service conditions. Verify the system design pressure and media compatibility before ordering. The 2-1/2 inch nominal size must match the mating component exactly.

Questions about this item

Should I choose the 150 or 304 version of this hex plug?

The plug is a single item combining both ratings; 150 indicates the pressure class and 304 identifies the stainless-steel grade, so no separate version choice is needed.

What does the 150 rating mean once the plug is installed in a piping system?

It designates a 150-pound pressure class, meaning the fitting is rated for the standard working pressures associated with Class 150 flanges and threaded components.

How does the threaded heavy connection limit what pipe sizes I can use?

The 2-1/2 inch NPT threads accept only matching 2-1/2 inch nominal pipe, so the interface caps the installation to that single trade size.
