Nice product
Nicely done chuck upgrade. I wanted something that would work with presta and schrader and work one handed. These fit the bill. Nicely made and finished too (made in Taiwan, so itโs good stuff). The 2 pack worked for me as I had two air hoses I upgraded with these. Takes a minute or two to get the hang of using them, you do have to screw them _on_, at least a couple turns, but they pop off without unscrewing. So not the chuck for a busy shop where youโre doing 50 tires a day, but for a home mechanic these are perfect.

A Game-Changer for Presta and Schrader Valves!
I almost didn't buy this pump chuck because it was listed as a frequently returned item, and honestly, if something's going to be a dud, it's usually the thing I pick. But I'm so glad I took the chance this time! I recently bought a new bike with a Presta valve, and after a lifetime of using Schrader valves, I was completely stumped. Pumping up my tire became a frustrating ordeal. That's when I found this Jaco chuck on Amazon, and its versatility for both valve types immediately caught my eye. Despite a few reviews suggesting it was difficult to use, I found it incredibly functional. Switching between valve types was a breeze, and the quick-release feature is an absolute game-changer. I was skeptical about the quick release working since the instructions mentioned screwing it onto the valve, but I was wrong โ it couldn't be easier! Jaco's patent mentioned in the product description must truly be valuable because this feature is a lifesaver. If you're struggling with different valve types, especially Presta, this chuck is a must-have.

Work alright for presta, but not perfect
I was sick of the cheap plastic inflator head on my air compressor tire inflator. It didn't seal well and made it difficult to set precise air pressure in my presta valve bike tires. This chuck is all metal and looked to be high quality and more durable. There is a bit of a learning curve to using it properly, but there are nice full color instructions included. Once properly screwed onto a presta valve it seals tightly and does not leak. It easily and quickly detaches when done by pulling back on the blue collar. The directions say to twist the collar on 2 or 3 turns to seal it to the valve, this is correct, but that's full turns, so more like 5 or 6 half turns when you're trying to screw it on with one hand. For the price, I wished they included some 1/4" male to barb fittings to be able to attach these to the end of a hose that doesn't already have a male 1/4" fitting. I also wish there was an option to purchase one at a time for half the price. I only needed one, but at least I have a back up now. This is probably the best tire valve air chuck design I've used so far, but it's still not perfect. You really need to screw it down tight or it will leak with slight side to side movement and you have to make sure you quickly pull the chuck straight off when you're done or it will leak. I will update this review if I have any durability issues. The only thing I can think that would wear would be the internal rubber o-rings. I have also not tried it on schrader valves, only presta.

Great chuck when you need both Presta and Schrader.
Great chuck allowing me to easily flip between Presta on my mountain bikes and Schrader on my kids bikes.

Ok so far
Ok so far. Aired up MTB and car tires with some hassle, will update soon. Update: I returned this set because it leaks on SHORT presta valves. It worked fine on long presta valves. You probably don't need 2. Overcharging for chucks you don't need is unnecessary. Sell them 10 each instead of 2 for 20. Mfr asked to contact them, but the link doesn't work for returned items. I have not used the $30 Silca chuck so I can't compare them unfortunately. If this was $10 it would probably be an easy buy over Silca though. I got the full set of JACO chucks to try their automotive ones. Same issue: Presta chuck leaks only on a SHORT valve stem. It holds long enough to fill it up, but if there's any sideways pressure on the chuck it will leak. I also noticed the 'quick release' sleeve of the second round of purchased worked way better than the first. They were stiff and hard to move in the first set of chucks I received. Possible QC issue.

Does not work, don't buy this
I have been using a JACO analog tire pressure gauge for years with not problems. So, when I saw the digital 200 PSIG air gauge and bike tire adaptors at such a great price, I purchased them. FRUSTRATION, FRUSTRATION and more FRUSTRATION for the get-go. First the sealing O-ring on the end of the braded hose will only seal the original Shrader fill/clip. Second the really cool chrome and blue air chucks do not grip the bike tube Pristas valves thigh enough to hold air. It's an air leak mess, impossible to fill modern bicycle tubes or tubeless tires. The sealing O-ring on the braded hose does not seal the chrome/blue P/S air chucks. Good idea but poor design and quality control. JACO you should have sent a few of these out to your valued customers to do a little testing before you gave them to the general public. P.S. I'm keeping the digital air gauge, great product, it works flawlessly on automotive tires. And with a Prestia to Shrader screw on adaptor from my local bike shop the digital air gauge/fill works great topping off my road bike tires.

Amazing!
Connects easily to my compressor air chuck for bikes (Jayco digital air Chuck) and locks on firmly with no air leakage, unlike other Presta lever locks. This is the real way to do it right the first timeโฆ.

High Quality and Easy to Use!
This is really quality made. The chuck slips on a Presta stem easily, you push down and twist a few times and that's all there is to it. Don't forget to use some plumber's tape on the threads when you screw it on to your compressor. Just be careful not to over inflate those bike tires. Mountain bikes take between 20 and 30 PSI.

works very well
Presta and schrader valves both need to be pressed in, before you lock and screw in to further seal it from leaks. after a month, the chuck can no longer seal due to wearing out of the metal grip

Not for me. Returned.
Appears well made made but functionality is extremely questionable. I purchased a different setup to achieve what I wanted and expected.

Not as easy to use as described.
Difficult to screw onto presta valve. Not as described in my opinion.

Bought 59 AUD a year ago and they broke, up to 191$ today. Not worth the price
Worked great for about a year. Then, 1 part fell when using it which makes the device unusable. I bought a 2x pack a year ago for 59 AUD. Today's price: 191 AUD. How come?
