As Expected. Well Manufactured
I used a couple of these to plug the test port holes in my sprinkler system vacuum breaker when the test valves began leaking. They worked as expected. Pros: - True 1/8" MNPT. - Very smooth surface and threads. - Withstood application of Teflon tape and standard tightening with an allen wrench without any problems. - Heck of a lot cheaper in bulk than big box stores. In fact, this pack on Amazon is only a mite more expensive than purchasing from overseas on the big online auction site & is delivered in 2 days versus waiting weeks. Cons: - None yet.

3/8 NPT - Well made, perfect taper, good metal
Threaded perfectly into these AIV pipes after I cut the threads with a 3/8 NPT tap. Saved me from having to permanently weld caps on. Internal wrenching is much better than the external cast iron plugs I would have gotten at the local hardware store. The brass is also less corrosive and just plain looks better. Very professionally made. Fine quality.

Quality items!
Plugs were finely machined, Allen type socket fits tool perfectly. Only needed one, but since these are so good, I've found others I used with ugly square protruding tops that I replaced for a much cleaner look on a show vehicle engine.

GREAT
These are really nice air orifice plugs; they just don't' tell you that they are METRIC SLOTS; the threads are SAE, but the allen wrench is metric.

Sprinkler Test Port Plugs
Worked to plug up the problematic test cock port holes in my blowout adapter. Sealed up with teflon tape and worked fine.

Nice quality hardware
Really well made and well machined plugs. Used them to replace the plastic plugs in some marine exhaust manifolds. Work perfectly.

Very well made, perfect fit
These are very well made, no burrs and nicely finished. The fit was perfect. I used them on an external air tank to increase my air compressor capacity.

Exactly what I was
Love it! It is exactly what I need . I am surprise this even existed. I needed to plug a hole on the side of my supercharger that was drilled out to install a methanol/water injection nozzle. I no longer want the nozzle there and needed something with 1/8” NPT thread to plug the hole. This item was exactly the size and threading
