## Questions & Answers

**Q: When the closed flow chuck is attached to a valve, does air flow in both directions, both into and out of the tire?**
A: when connected air can flow either way ... flows to the side of lower pressure. for example, if you were filling your tire using a compressor, if your tire was lower pressure than the compressor gauge, the air would flow TO the tire.  however if your tire was 25 psi and your compressor gauge reads only 15psi, air would low FROM the tire.  when chuck is not connected, no air will flow thru it ... that’s why it’s called a closed chuck.  different than an open chuck which would still allow air to flow thru it even when chuck is not connected to anything.

**Q: I want to use this with the epauto tire inflator, how can I go about doing that?**
A: Works fine on a Hunter TC3250

**Q: So that means you have to remove the alve core to inflate ?**
A: no you dont need to remove the valve core to inflate. just push on stem so it presses valve stem core and it will inflate

**Q: Does this work well for bike tires? My new compressor is a screw-on and you lose a lot of air unscrewing. I need to be able to quickly detach.**
A: Any tire that uses a schrader valve this chuck will work.  And it quickly attaches and detaches.

    Works very good.
  

*by J***R on Reviewed in the United States on July 13, 2023*

Perfect replacement.  I needed a new oring for my old one.  It was cheaper to buy the replacement than find the correct oring for the old one.

    Best open flow chuck I have found so far
  

*by B***R on Reviewed in the United States on August 20, 2016*

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.
