There is nothing keeping them from swiveling BUT they are not designed to swivel as you work, if that's what you mean. You would have to get a high-pressure hydraulic swivel if you are working and the hoses are constantly moving. If you are moving the hose around while under pressure a few times, I believe that would work. I use these on a loader control and the hoses stay pretty close to their original position while working. **Q: Will these plug into John Deere tractor?** A: I don't think so; they were close to the stock fitting for the compact Ford (Shibaura) 1310 but slightly different which is why I bought several sets. **Q: Do these fit John Deere snap couplers?** A: It matched the factory couplers on my 4320 **Q: Where does this ship from?** A: US Amazon warehouse ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid fit, no leaks great value for standard tractor hydraulic hookups *by A***. on April 19, 2026* I picked up this 1/2" ag-style hydraulic quick connect set for my tractor attachments, and overall it’s been a reliable and cost-effective option.
