TecUnite 4 Pack Metal Valve Stem TR-416-S 1 Inch Outer Mount Fits 0.453 and 0.625 Inch Rim Holes

Purchased new tires for my 4-wheeler and these help keep the air in. What more can you say, they do their job.

needed to replace a missing one on my wheels.

Primarily I got these to pressurize pump bottles that I use for fumigation, but I'm noticing that there's other uses to these. Besides valve stems for car rims and stuff like that. Now the build quality on these are very good. I've yet to find a valve stem that wants to leak on me. I've had these before on an actual wheel for a different for a car and it never failed in. So if you need to use these for miscellaneous projects they will work out just fine

These are an entirely suitable TR-416-S valve stem, and were exactly what I needed to add TST TPMS sensors to my Jeep Liberty, with adequate clearance between the sensor and wheel, without having the sensor stick out any further than necessary.But the description is misleading in 2 ways:1. They come with the needed rubber gaskets only for rims with 0.453" hole for the valve stem. The description says they also fit 0.625" holes -- and they will, but only if you provide the needed gaskets. The Similar (but slightly longer) TR-416 valve stems described the same way normally come with both gaskets. I down-grade them by one star for this. If they either provided the extra gasket, or didn't say that they fit 0.625" holes, or said that you have to provide gaskets to fit the larger holes, I'd have given them 5 stars.2. They're described as 1" stems. But they're only about 3/16" shorter than standard 1 1/2" TR-416 valve stems. These are actually 1 1/4" from the inside of the mounting shoulder to the end of the stem, and 1 1/8" from the gasket to the end of the stem. So these really should be described as 1 1/4" stems, not 1". I did NOT downgrade their star rating for this, only because all manufacturers describe TR-416-S valve stems as 1" even though they're actually 1 1/4".The finish on these is not quite as good as the VTR valve stems I've purchased previously, but that's a purely cosmetic issue, and in practice no one will ever notice. And the hex caps on these are better than the VTR's knurled caps.At the same price for this or equivalent VTR stems, I'd probably buy the VTR stems instead of these, because of their slightly better finish.I ran into one additional issue that is likely common to all TR-416-S stems -- the threaded end (where the valve cap attaches) is fairly short (barely longer than the included valve cap), and the rest of the stem is much larger in diameter. This short threaded end is barely long enough for one of my valve chucks (Coilhose Pneumatics CH15A; https://www.amazon.com/dp/B008PZ7M26/) to latch on properly. So it's possible that some chucks are simply incompatible with this stem design. The few other chucks I've tried don't seem to have the same issue, and the threaded end is certainly long enough for normal caps, so I can't really blame the TecUnite stem for this issue. Nevertheless, I wish the original designer (VTR ??) had put that diameter transition just a couple mm further down the shaft.NOTE -- you may need to bring a non-impact 14mm deep-wall socket when you have these installed. The nut to secure these is 14mm, and with aluminum wheels the socket used to secure that nut needs to fit in a shallow recess around the valve hole. The tire shop I use seems to have only impact sockets, which are too large to fit the recess. And at least for the wheels on a 2007 Jeep Liberty, an impact socket is too large in diameter to fit down in that recess. They had to scrounge for a non-impact socket that (with its smaller OD) would allow installation in my wheels. But that's not really a fault of this product -- I suspect it's common to most/all metal valve stems with the securing nut on the outside of the wheel, and few tire shops seem to use metal valve stems like this very often.

Exact replacement for the ones that I bought 17 years ago.

If you're repairing tires on utility trailers, down to 12" rims, USE these!! Throw all your rubber stems in the trash and never buy anymore. Those are junk and not worth the packaging. The last pair of rubber stems I had on my trailer weren't on the trailer 15 months before they dried out and sheared like a cheeto.These are the real deal, machined very nicely, tight tolerances: Solid steel stem, one piece- the rubber fits your standard 12" trailer rim ' 0.453" stem hole' precisely. They install, tighten up, seal; everything just works so beautifully. They actually made my tire work a pleasure. I'll never buy a sorry rubber stem ever again.

I bought these mainly because I like the design and size, which make it a perfect fit for installing it in my Cat D5C dozer fuel tank cap so I can put a tiny bit of air pressure in the tank to puah the fuel to the injector pump by simply cracking the fitting on the line where it connects to the pump. Will make it easy to add a bit of anti-gel to the fuel without the wait for the treated fuel to make its way with only the little hand primer that's found on Cat engines with mechanical pumps from the days before the electronic controlled were introduced. I always carried a reefer tank cap with a fitting installed in it for those times I'd be doing a drop and hook at a shipper or receiver that had let the reefer tank run dry. Turned a hour or more chore into a 10 minute task that's simple as can be. Very handy to have.

“Fits .625” no it doesn’t. Doesn’t not provide REQUIRED gasket.
