TAILONZ PNEUMATIC 4Pcs 1/4 Inch Air Tool Swivel Fitting 360 Degree Swivel Air Hose Connector Industrial Swivel Portable Air Tool Adapter

Waste of money. I have no idea what all these other people are saying about how they were great and no leaks perfect seal... Out of the pack of four I got every single one leaked....from every possibly place... Every seam. Every joint. Like seriously from all sides they leaked. I could hear the air and I sprayed a tiny bit of soapy water to identify the leak... Every seam and cornered surface where it was not a single solid mass leaked. On all 4.

I have installed several of these and have found that they all leak quite a bit of air. They are also difficult to fully tighten up to what you are mounting them to as the nut has too thin of a profile, which means a standard thickness wrench won't be able to fully tighten, so you have to use a thin profile wrench and still challenging to full tighten as the part tightens down on the wrench that you are using to tighten it down, causing it difficult if not impossible to fully tighten. Too many corners cut in this part making it worthless and not worth buying.

They're ok... not the best by any means but ok for the price (cheap). They leak after being sealed, not much but enough to hear. Probably wouldn't recommend if you're using a small compressor like a pancake or hotdog style. Lowe's and home depot have their brands, the kobalt ones are good just don't buy the ones with the adjustable air flow wheel thing. Whoever thought that was a good idea probably got dropped as a child.

Too much trouble to return. I took it apart to check the o rings and they aren't damaged. I put heavy grease on them and retested. Air leakage was cut in half bust still leaking real bad. I will try to find thicker o rings to repair this. If your like me and constant hiss of leaking air gets on your nerves, don't buy this.update: I previously left a 1 star review because of the leaks, the company contacted me and offered to send me another set so I accepted. the new set is much better. I'm upgrading them to 4 stars

Put one on and leaked. They look rough out of the package. They might be ok for the home mechanic but not every day abuse. I will be returning mine.

After reading through many of the reviews here I was a bit apprehensive to order these. Many reviewers liked them but many noted that leaked air shortly after being put into use or in some cases right away. In my case I have yet to have one leak. Not only that, but these are completely and easily rebuildable. An easy 5 stars as far as I’m concerned.

I purchased these valves after reading some reviews. After carefully installing the valve, air starting leaking. I swapped them all out and all had an air leak. I really don't suggest buying these valves.

I added these swivel fittings to two of my air hoses and used them for about two hours so far, without any issues. They are well-made, they articulate smoothly, they do not leak air, and the price was very reasonable.Attaching one directly to each tool would have worked a little better but would have also made the tools too bulky to fit in their hard cases. Putting them on the hoses makes the tools slightly less maneuverable but that wasn't a problem for me and the benefits outweighed the drawbacks in my case.

I have installed all four of the air line swivels on my air tools and none of them leak. Makes working in tight spots alot easier
