Great for DIY pressurized containers
These valves came in a two pack. They are good quality and the threading is slightly thicker as it threads in. This was perfect because I used it to be able to pressurize a scepter water can. I would recommend these to anyone!

leak free, brass, 1/8npt pipe thread
Way cheaper than I could buy vocally. Common 1/8"-27 thread tap. I used 11/32 bit before tap, worked fine. Holding 150psi air pressure with 250° temps.

Works as it should
Put one on my fuel regulator on my f-250 7.3 and it's all good. Not much else to say other than it works.

Good to have if you own a CTIS equipped truck.
Just what I was looking for. These are what is needed to replace the Junction between the valvestem and CTIS wheel hose on a 900 series 5ton military truck. They may be the same for an LHS or LMTV truck as well. If you own one of these trucks get a pack of these as they are a weak link in the system and are easy to break when changing a tire. Coming with the schrader valve is nice as well as it’s a place to delete the CTIS at that particular wheel.

Many uses
I used this to build a boost leak tester for my Mazdaspeed3. I drilled a hole in a PVC cap and used this in conjunction with the Spectre 3" to 2.5" Intake Coupler and it worked perfectly. I added RTV on the threads for safe measure. I only tested it up to 20 psi but worked for what I needed it to.

Good quality valves.
They are as advertised and are of good quality. What more can I say? They don't leak and are nicely finished.

Works
Working great so far. We will see how long it keeps a charge. Used to convert my WP shock over.

Solid brass, threads are clean. Some of the valve stems were a little loose - presumably from being shaken around in transport - but were easily tightened back up and worked fine.
