    I've found that applying heat with a micro torch works well. It expands the nut and breaks free of the threads. When using the pliers to try and unscrew it,, don't grip the nut over the threads, grip it further down where there are no threads.. I still replace the nut as it has corrosion in it the threads. If the heat doesn't work, I use a similar method of cutting except I go further down the nut than just the 1/2"-3/4" you went. If you go 1/2 - 3/4 the way down the nut, it's much easier to spread the nut open with the screw driver breaking it free of the handpiece threads.

      Agree griping nut at thread would make the cut parts press harder against threads. I also carry a dremel in the car. Have not had to do this but a dremel seems like a good tool for this. I could be wrong

      also wd40 sometimes will penetrate and not need to cut.

    Before even attempting this I would bend the tube back and soak the nut in a cup of very hot water for 10 minutes. The cavicide turns into glue and soaking it softens that up. I then gently use some adjustable pliers to work the nuts loose. It works 9/10 times and if you are careful you don’t even have to replace the nut. Scrubs those threads with a wire brush and you’re good to go.

      Great tip- my way works 10/10 times. 🤣 Honestly usually by time I get to the unit, there are usually tool marks on the handpiece nut. I think that the issue usually is related to the corrosion of dissimilar metals (aluminum and steel) instead of cavities. I could be wrong, but I'm always trying to figure it out.
      I guess at the end of the day, there is more than one way to skin a cat.

      @@DentalEquipmentRepairChannel Really the best solution is to get the dentists to understand that they are doing significant harm to their handpieces by not removing them. You as well as I know that handpiece has not been lubricated in months. The corrosion is caused by the liquids from the sanitizing wipes seeping down into the threads and causing the corrosion. If they would take it off, lubricate and sterilize everyday...problem solved. Not to mention it is just really unhygienic not to be sterilizing the handpieces.

    Good video thanks
    If you place the hose in hot water for 20 secs the hose will soften and you can easily slide the new dci connector

      That's a good tip. I use either hot water or hand sanitizer usually.
