These air chucks are of sturdy construction. They worked as intended and expect them to last a long time. Good product, highly recommended. I adapted these to an a/c vacuum pump to deflate my tires which helps with breaking the tire beads.

Just used it this weekend to air up the Jeep after some off road fun. I'm a fan. Previously I had a nice air chuck/gauge, but trigger activated, so I had to squat next to each tire for about 1.5 minutes to air up. With this, I just pop it on and can stand up and walk around. Much nicer at my age. As an added bonus, my Jeep has an electronic tire pressure monitoring system, so I can stand outside the drivers door and watch the pressure get to where it needs to be, then head over to that tire and move the chuck to the next tire. Very nice. I got the closed flow, so it doesn't flow when detached from the tire. I go wheeling every weekend, so this will get lots of use, but seems like a quality product that should last. Since it was a 2-pack, I have a spare in my toolbox in case one does wear out.

I purchased the OPEN flow version of this chuck. This is the first one out of the 4 models I have tried that works and works well. Easy to latch on, stays latched on and it doesn't leak. I'm skeptical at this point that any of the chucks - including this one I'm reviewing - are consistently worth anything these days so this may be luck of the draw. In this case though you get 2 chucks for the price of one to improve your odds! One wouldn't think it would be hard to find a chuck that works but the other models I have tried leak when attached to the valve stem. I had to take apart one of the other models and use my Dremel to file down the piece that depresses the valve because it was too wide - and it still leaks. Craziness. There seems to be lots of confusion between an OPEN and CLOSED chuck. I think I have it figured out so I'm going to try my best to explain the difference in excruciating detail. If you already understand the difference you will want to skip the rest of this review. BOTH the OPEN and CLOSED chucks have a pin that depresses/activates the Schrader valve in the valve stem on the item you are trying to inflate. The key difference is that a CLOSED flow chuck WILL NOT allow air to flow through the chuck itself unless it is actually attached to the item you are trying to inflate. An OPEN flow chuck WILL allow air to flow through the chuck even if it is not attached to something. If you had a big box of random OPEN and CLOSED chucks you could quickly sort the CLOSED vs OPEN chucks by trying to blow through them. If you can blow through it it is OPEN. If you can't it is CLOSED. So why the two types? The CLOSED flow chuck is used when all you have is a compressor/pump and a hose. The OPEN flow chuck is used when you additionally have an inline pressure gauge or other device with its own flow control. Summary: get the CLOSED flow chuck unless you have a device inline that provides flow control in which case you want an OPEN chuck. All that said, I couldn't find a definitive answer using Google search as to WHY it would be bad to use a CLOSED flow chuck with an inline device with separate flow control. It seems that once the chuck is attached then it isn't providing any flow control - so why the big deal? I'm guessing it is a safety issue but I would sure like to know for sure if someone knows.

I change my own tires at home using a manual tire changer. One of the most challenging parts is getting the bead of a new tire to seat on the rim. Unless you have something like an air blast tank, the beads usually droop away from the wheel rim. The result is that you can't inflate the tire because the beads aren't sealing. This is where I advise you NOT to do what I do. I grab a can of ether (starting fluid), spray some inside the mounted tire, and then light it on fire. The ether combusts immediately, causing a large pressure wave that seats the beads. The trouble is that the pressure soon drops and the bead can suck itself back off the rim, at which point you're back to where you started. Unless, of course, you've clipped a locking air chuck onto the valve stem. The incoming air prevents the tire bead from falling off. Yes, seating a tire bead with ether is dangerous. I don't suggest you do it, and all the usual disclaimers about the associated dangers of fire and compressed air apply. For the less adventurous among you, this chuck is nice to have if you want to inflate a questionable tire, like one that has cracks in the sidewall. A blowout up close can be very dangerous, so you clip the chuck to the valve stem, walk far away, and turn the air on from a safe distance. If the tire explodes and rips the quarter panel off the car, at least you're far enough away to keep from getting hurt. We don't normally think about the damage a tire can do, but there's a TON of stored energy in there from all the compressed air. I usually don't use this tire chuck. It's more convenient to use the inflator I have with a built in gauge. However, when I'm dealing with a questionable tire or I have to seat one that I just mounted, I'm glad I have it.

Wanted to try an open flow chuck to assist in mounting large truck tires. My older angle lock on chucks kept popping off under pressure so I ordered the EPAuto 2 pack to make a short lock on hose to help seat the beads. These chucks held well under 160 psi and the open flow was a big help with the valve removed from the stem. At first I was annoyed to buy a 2 pack when I only needed one but that was the most cost effective way to buy. Happy that I did, I wound up using the extra one almost immediately. Good product, good buy, time will tell on durability but good so far.

Built a little slimmer than my current chucks but they work great.
