A NPT or metric is the standard
4/5

As for the NPT threads, there are no issues. However, be aware that the hex socket is actually metric and 8mm in diameter. In either case, you might have to strip the socket like others described. Otherwise, it will be fine.

Everything went according to plan
5/5

The product is well made. The leaks in the test valves in my sprinkler system vacuum breaker were solved by putting some of these in the test port holes. Everything went according to plan.

Please be patient while we process your request The surface and threads of this item are extremely smooth. Please be patient while we process your request No problems were encountered with the application of Teflon tape and standard tightening with an allen wrench. Please be patient while we process your request The prices of large box stores are so much cheaper in bulk. As a matter of fact, this pack on Amazon is only slightly more expensive than purchasing from overseas on the major online auction site In contrast to weeks of waiting for delivery, this takes just 2 days. There are a few cons Please be patient while we process your request We do not have any.

The quality is excellent
5/5

In order to plug the expansion tank fitting on the bottom of my air separator I needed to install it in my heating system. My goal was to use the same material because it was brass. (It wasn't necessary for me to do that. counter-sunk hex socket means there is no way for it to catch. The plug site is even with the bottom of the floor joist, so I wanted it to look that way.

This is a very soft product, which cannot be removed
3/5

The experience was very bad. Indented hex slots for tightening or removing the nuts, in combination with the soft brass, would cause the nuts to deform and expand out, making it impossible to remove. While I tried to use a hex key very tightly to the socket, I still cannot release it. Striping is all it does. In the meantime, all I can do is attempt to tap it in the middle and drill in the middle, hoping not to ruin my part. This is the dilemma because I am unable to Disappointed to the core.

I'm happy with these plugs
5/5

They are of good quality. My expectations were that it would flow more smoothly into the manifold, but I believe it has to do with the way the tooling of both parts was done.

This is a good product
5/5

A piece of extra fitting on an air tank was plugged with these plugs. If I want a tight seal, brass is my choice. The allen head is 8 mm in diameter.

Is the hex with NPT metric? Except for the combination of the metric hex socket on an NPT plug, this product would easily be a five star product
4/5

That the item description does not list this error is even more problematic I cannot however justify giving less than four stars to the product because the thread fit was so good, and the product was otherwise so well-finished.

These are the Sprinkler Test Port Plugs that I used to plug up the holes in my blowout adapter caused by the problems with the test cock port
5/5

I sealed it up with Teflon tape and it worked just.
