Description

Alright, pipe fitters and plumbers – here's a 3 inch threaded (NPT) square head plug, made from 304 stainless steel.
It's a 3-inch male NPT plug, so it screws right into female NPT fittings.
Brand new, never used, in original packaging (or plain box, but it's fresh).
The MPN is SS151141304, and the end A diameter is 3 inches.
Fitting type is plug, with male threads on the connection.

The square head lets you tighten it with a wrench easily – no rounded corners to slip.
Perfect for capping off pipes in plumbing, hydraulic, pneumatic, or industrial systems.
NPT threads are tapered, so they seal tight – use some thread tape or pipe dope for a leak-free fit.
This thing is heavy-duty and built to last.
Whether you're capping a water line, gas line, or just need a spare plug, this one fits the bill.
The 3-inch size is pretty big, so make sure your system needs that.

It's simple, effective, and does exactly what a plug should do – stop flow and seal tight.
No UPC, but no worries.
So if you need a reliable stainless steel plug, grab this one.
It's a workhorse.
