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 purchased these chucks to replace the end on my old tire inflator with gauge ( I only needed one, but it is nice to have a back-up). The old chuck was slow to inflate, and had to be pressed tight to the tire to work (even though it was also a clip on connector). I just unscrewed the old chuck, applied a little thread sealer, then installed one of these. These chucks work so much better! Just clip them on and they work, no pressing, cursing, or fighting needed. Also, the air flow through these is amazing... It seems to take only second to inflate my jeep tires (it used to take forever).

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.

I bought a Rhino tire inflator gauge and it came with a “closed†chuck meaning that air would only flow if the valve was depressed with a core valve. This type of air chuck wouldn’t work to inflate sports balls (football, basketball, soccer ball, etc). So I ordered the open air chuck and swapped it out. Now my Rhino tire inflator gauge blows air out when I press the trigger.

First it worked great to allow excellent air to the tire, rim that i was putting together. Have a ball valve just prior to the chuck to control flow. i turned on the compressor with the ball valve closed. allowed the pressure to build up then opened ball valve and observed the tire closing the gap on the rim. the first move was inches almost to the edge of the rim. next it went to the edge and sealed the bead. this was my first time using an open air chuck which i read about on you tube and such.

This chuck was designed to be used on a tire valve that has the core stem in place, which greatly restricts the air flow. Having said that, it is a simple matter to make it "open flow" just by drilling it from the back to the front with a 7/16" bit. A 1/4" bit may also work, but I didn't try it. This knocks out the pin that is intended to depress the valve core and opens up the restriction. Of course, you will have to attach this to a shut off valve to make it practical, but you knew that already. This cluck is useful for inflating tires that have hard to set beads, such as tractor tires and some auto tires.
