Good
Works as expected. The brass part and chuck are great. The clamps are useless Chinese crap which I had replaced with actually working usa made clamps.

Great Product to Fix Air Hose on Inflators
This locking tire inflator chuck worked great with my old Coleman Inflator Pump! It was easy to install in my pump’s 1/4” ID rubber hose and the clamp fits tight. I just inflated my truck tires to 32 psi. and it worked great. No leaks and it locked well onto the tire nozzle threads.

2 pack Air Chuck
Really like the quality and the fact that it’s made of excellent metals for strength and longevity. The old chuck wore out with relatively very little use because of the aluminum parts. See the photo of the old style where it wore out prematurely. Was easy to replace the old for this new replacement air chuck and it fit like a glove. This style of chuck is an improved design over the old one. Comes as a two pack so the extra will go on the other pump I have that also needs updating. Great price and value, BRAVO!

Works but a little clunky!
There are 2 air chucks with 2 clamps per order. Price is good (read that cheap!) and nozzle barb able to hold on to valve stem well enough. If air hose is wiggled, the rubber seal inside the air chuck won’t hold and will leak. Since the hose clamp is bulky and sharp, we used marine shrink tubing to wrap it for more comfortable hold. There are other manufacturers (Lock N Flate, Jaco, Jinky, Astro, etc) who made better chucks but none sell 1/4” barb fittings to allow you to adapt to your old but working air compressor.

Durable. Good quality
Works great. Durable design. Better quality than the connector with the plastic lever that inflators come with.

Perfect
Great fix to my VIAIR Air hose! Original was a 90 degree and hard to fit on valve stem. Snapped on me while filling up. This was a perfect replacement, should have done this awhile ago.

Fiddly seal
Replaced chuck on my bicycle pump. Easy to use, tolerates high pressure. Does not always seal when attached to the valve stem, need to “screw” it on to get a good seal. Really annoying on a low volume high pressure tire, lose all the air before the chuck seals. Great concept, needs tuning.

Easy to install
Good quality . The hold down springs is strong. Worth the price.

Very good replacement for a faulty tyre pump's valve connector
Even from when it was brand new my 12 volt electric tyre pump had a slightly dodgy tyre valve connector. Really I should have immediately sent the whole thing back to Amazon for a full refund! Instead I lived with it for over a year until it finally became impossible to use. I knew the electric pump itself was still ok so I didn't want to scrap it and then have to pay another £30 - £40 or more for another new electric pump. For £6, including Prime free delivery, I ordered a pair of these Toolwiz 1/4 Inch brass tyre valve connectors . They arrived the next day. Using a sharp knife it was very easy to cut through the rubber tube where it came out from the broken old connector, which is noew in the rubbish bin. After I placed the clip over the end of the tube I inserted the new connector and tightened-up the clip. As I'd hoped, the pump immediately worked well again. I shall keep the second new connector as a spare but they are so well made I doubt I shall ever use it myself - it would be good to give to friend or relation if they ever need to replace a broken tyre valve connector!
