Presta Valve Air Chuck, Digital Bike Tire Inflator Gauge for Air Compressor

Just used this to seat my 29" presta valve mtb tire and it worked amazingly! Air flow was definitely fast enough to seat the tire. Highly recommend

I bought this to use with tubeless bicycle tires. Hadn't needed an inflator before for presta valves. But tubeless bike stuff has a learning curve and a clip on inflator is a major timesaver when doing these installs. It works right, is well made, and sturdy. This will replace my Schraeder-only inflator. Which is not very old. But there's no reason to have 2. I've had it just a few days, but it's been spot on. My only regret is, I recently saw a better air chuck. The better one looks far easier to clip to a valve. Operator presses the chuck onto the valve and then squeezes a trigger to attach. It's a better, one handed, method. Currently the new style is overpriced, I might buy one if they come down in price. I bet the new style becomes the common type some day. But conclusion, this inflator is great. Big timesaver with presta valve bike wheels, plus it also works on normal schraeder style. I'm glad I bought it.

You must, must! Always use the same psi meter when dialing in your fav psi before riding (be consistent)! I used this product on my tubeless presta tires for my mountain bike. As pictured, there is a slight discrepancy between this product and my manual bike pump, that I have been using for years. It doesn’t matter which one (this product or a manual pump) is correct, what matters is that you consistently use the same psi meter! For example, I only use this product to fill my tires if they are very low, than I use my manual pump to dial in the pressure I want.. whether its bike trials, parking lot drills, gravel riding, and trail riding pressure matters so use whichever psi meter you are used to using when dialing in the final pressure. And always bring your manual pump to the trail head so you can dial in the right pressure just before you ride! We have had an air compressor for years now but have not purchased a presta valve adapter (like this product) for my air compressor as now the prices have dropped (they used to be quite more expensive in the past years) now that this product is relatively affordable I decided to buy it and give it a shot. First off, this product does inflate tires quickly and its simple to connect to an air compressor as it uses a quick connect instead of manually screwing it in each time. I also tested this on a shrader valve on my dolly and it worked fine. Based off reviews I will not be using this to inflate my car tires. I only give this product 4 stars because the locking mechanism is sub par and you have to push this adapter into the presta valve for it to get a psi reading. If you just lock this onto your presta valve it will either show up as 0psi or a really low amount of psi that is completely incorrect. Also, when I was inflating my front tire the digital psi readout on this product got up to 100 psi, when it was actually only about 40psi. Therefore, you can’t set it and forget it. Like other reviews mentioned the illuminated display and stock energizer batteries are a nice touch but since I have been using my manual pump for years I will stick with that to dial in the correct psi or make small adjustments and keep this handy for either inflating a near empty tire or use as a spare when my manual valve fails. YES! This product only gets 4 stars as well because it will also fail after about a year or so just like my manual pumps valve. This product will eventually fail you because mountain bikers (or anyone that rides tubeless) like myself use a tire sealant that will eventually get inside this product and cause it to permanently fail. I wish valve heads, like this product, had a pre-filter in it to prevent the tire sealant from ruining it, but I haven’t seen any valve heads with a replaceable pre-filter…yet! Hopefully one day they will engineer these valves correctly! In conclusion, this product is ultimately disposable and will fail but when it works it works well. Just remember to consistently use the same psi meter when dialing in your final psi before a ride. That is the main take away message. Enjoy and happy riding!!

Great product I needed it to fill my tubeless tire. Works great with my pancake compressor.

I use this on bikes and cars. It quickly adapts to presta and schrader valves with little/no adjustment. The gauge seems pretty accurate, too. It's probably a bit underbuilt for use in a professional shop, but for home use it's perfect. I got it for setting up tubeless tires on bikes and it works great to give a fast shot of air (with valve core removed) to set the beads. This tool made the often PITA setup a LOT easier.

If you have a compressor this is a handy tool for inflating tires that works well with Presta and Schrader valves. I checked the gauge against both analog and digital gauges I have and it is accurate. Comes with two Energizer AAA batteries - not the usual no name kind that don't last long. A little technique is required with bike tires. Car tires are easy, if you happen to lose a little air as you remove the hose it makes hardly any difference in pressure. With bike tires, especially at high pressure be sure to remove the hose smartly as to leak a little air on the disconnect can lower the pressure 5-10 psi. So, connect the hose and lift the lever to lock it on the valve then fill the tire with air, go above the pressure you want and use the air release button to go down to the correct psi - this will give you an accurate reading. Fold the locking lever down and smartly remove the hose by pulling it straight back from the valve. This tool is new to me - will it last - I think so - it is basically a standard digital car tire inflator with a head that will fit both Presta and Schrader valves. Super handy for when you are changing larger tires - 28mm and above - which take a lot of pumping with a manual pump.

I purchased this inflator to use with my compressor to rapidly set the bead and fill tubeless bike tires. The inflator seems to be well made and has a pretty easy to read pressure gauge. Overall, if you are someone that is going to install a couple tubeless tires every year or so - this will work. It will annoy you a bit, but it will work. If you are going to do more tires per year or if you have a bike shop - this is NOT what you are looking for. Here's the things to be aware of: - The "universal valve head" will NOT lock on to a Presta valve that has had the core removed. I prefer to do the initial inflation with the core out (after filling with sealant), because it fills and locks the bead very fast. To use this inflator, you need to put the core back in first. It will work that way - just not my preferred method. - In order to lock the head onto the valve you need to push down very hard. I mean really hard. (even the directions say this). If you don't, it won't lock on and inflate. - While you are inflating, the pressure gauge is all over the map. Once you stop inflating it takes a moment or two and the gauge settles down and reads the pressure. I didn't calibrate it - but it looks like it is in the right ballpark. Bottomline - this inflator works. But it's quirky to use. I probably would have ponyed up for something higher quality if I were doing it again. Not worth returning though - I'll live with it until it breaks. Hope this helps some of you.

This thing works great! I have only used it for tubeless presta valve set ups. The digital gauges make it easy. Great bang for the buck.
