Check your tape carefully! It may not be the problem of the valve.
Last week I replaced my front tire. It was a new tire, so I pumped it to the maximum pressure (40psi). However, later I found there was air coming out from the value. I thought there was something wrong with the valve stem so I bought this one and installed it, but it was still leaking. Then I removed the tire and cleaned the sealant, checked my rim and found a part of the tape covering one of the holes was broken, maybe because it was already worn, and was too thin to hold high pressure (I usually ride with 20 psi but I pumped to 40 when installing). It seems the nipples seal pretty well, so even there is leakage to the spoke holes from the inner side of the rim, air will finally come out from the valve rather than the spoke hole itself. So be sure that your tape is good before changing the valve. One thing I found interesting was that almost all tubeless valves on amazon have some negative review saying that they are leaking, I believe some of them might be caused by the broken tape. P.S. Tubeless Ready system uses tape, if you are using the UST system, which is without nipple holes, you will not have such a problem. My problem was solved after I replaced my tape, this valve seals pretty well.

Valve cores a little *too* easy to remove
Valves are tough and do their job, with two minor complaints: Because of the conical rim seat, they can end up not quite perpendicular to the rim, they hold pressure fine, but point away from the rim at a slight diagonal if you're not very careful. The valve caps thread onto the valve cores themselves, not the outer barrel of the valve, so it is easy, when removing the valve cap, to take the valve core out with it! This could be disastrous out on the trail. Every time it has happened to me, I realized it in time to get the core back in before losing too much pressure.

Quality Presta Valve for Tubeless Set Up
WTB is a big player in the tubeless bike tire industry. These valves do not disappoint. Easy to install and in three different sets, I have never had an issue with leaking. When installing, ensure you use a quality tubeless rim tape and overlap (two layers) over the hole for the valve. Recommend you cover the rubber portion of the valve that goes on the inside of the rim with sealant before you install. If you don't have experience with tubeless, it is much easier to seat the tire bead with an air compressor versus a floor pump. Pros: No leaks. Valve core removes easily. Cons: None that I have found. I have tried several different brands of tubeless valves and think that WTB produces some of the best.

Work great.
Got my brand new bike home the other day and the tubeless setup had not sealed on my front tire, aired up the tire and broke my valve stem. Ordered these and replaced when they got here, worked great and one I got the tire seated and sealed have had no more issues.

Well Made and Function
I bought another, highly rated, brand before these, and could not get them to seal around the stem. I'd heard the aluminum stems can have problems--including failure, since they are aluminum and we are heavy handed humans--but not that they wouldn't seal. After multiple tries I bought these and they sealed. And, they're brass. A tiny bit more weight for a lot more security.

Great tubeless results
I've converted both my front and back WTB ST i40 rims with these valves. Just made the smallest possible hole in the tape, pressed the valve through and hand tightened the nut as tight as possible. I get the tires completely seeded to the bead with soapy water and then remove the valve core to add my sealant.

Affordable and Functional
Easy to install. Sealed up nicely in my WTB rims against wtb tubeless tape. Not fancy like some but very functional and affordable.

Injecting sealant will be harder than you expect
These fit very well on my WTB i19 rims. This is not a surprise; I chose these valves because I hoped compatibility would be at its best. Note that you can get a better seal by pushing inwards on the rubber while tightening the retaining ring. The problem I found was when it was time to inject my sealant. The hole opening into the room is very narrow, preventing my sealant injector from going all the way in and limiting the rate at which I could inject sealant. I had to do it in several steps since the solids in the sealant were starting to come out of suspension. If I was starting again, I would try a different brand first.

Does the trick - weak cores
Installed these stems when I converted to tubeless. One did not seal very well against the wheel, but with some tightening of the nut, it works fine. This will vary wheel to wheel. I found the cores to be very prone to bending, and have since swapped them with Vittoria brand cores (available in a 10 pack with a handy tool). No issues since then. The brass looks pretty sharp, too.

Questionable design.
This valve stem somehow got in-between the two walls of my rim when I tightened it. I had to break off a bunch of the rubber to get it out. Not sure how this could be overlooked in the design process. Don't buy these if your rim has a similar sized valve hole to mine.
