    Nice job! I've done that a few times myself.

    What's with the toeless slippers in the shop?

      Slippers? Those be man-dels, not to be confused with the flip-flops certain Home Depot customers wear no matter the temperature or weather.

        I like ear clamps - not as cheap as conduit, but cheap enough. Much easier, certainly.

          I went through this with my recent air line plumbing in the metal shop. I used copper for the main line and had a low pressure PEX distribution tapped off that. So I had the PEX rings and scrap tubing. Below is a pic of the ends that were done using some 1/2" PEX collars on hoses with various fillers of either PEX or in one case some black vinyl tubing I had on hand to act as packing. In all cases it required a bit of an extra push to put the "stack" of goodies on over the barb fittings. But each final crimped solution is holding really well and is VERY firmly locked. They AIN'T coming off any time soon ! ! !

          I did 1/2" PEX sleeves and PEX copper rings on the 1/4" green Flexilla hose used for the smaller lines. It worked like a charm. I actually had to use some automotive plastic and tire buffing goop as a lubricant to get the hose onto the barbs with the PEX in place. No way I could slide it on over the hose ON the barb. And then once crimped it sure wasn't going anywhere.

          On some 3/8" ID hose I used 3/4 PEX over the hose with a PEX ring to lock it down. In this case I needed about two or three layers of electrical tape as additional filler between the hose and the PEX tube. But it's easily surviving the high pressure side which is the delivery pressure to the plasma cutter.

              I do it all the time. 1/2” PEX rings are a bit small for 3/8” hose. I stretch them a bit by hammering them over a tapered socket to expand them.
              I also fix 5/8” garden hose with 3/4” PEX crimps. They need to be expanded a bit too using a socket.
              Actually you can use a round bar that fits inside the rings to expand them if you don’t have a socket the right size. Just slip the bar in and hammer the ring and it will expand it.

                I have a coiled 1/4" air hose that got kinked, so I cut off the bad part and tried to fit the good part on the barb. But the barb is free to move inside the brass connector so I could not use much force to get it completely on, and it popped off after a few minutes of use.



                It's pretty old, from Harbor Freight maybe 12-15 years ago, and it's probably the same as they now sell for $4. It is described as 20' nylon:

                Maybe the $7 25 foot polyurethane hose would be better:

                I had to look up PEX rings:

                  This makes crimps even in bit tougher material:

                  Might need to make your own swaging dies to suit the size but those are easy-peasy to modify or make
                  (round dies could be preferable over hex for hoses)

                    I bought that same crimper to crimp aluminum ferrules on cable. I haven’t played with it much yet.

                      The China outline and its flag displayed in the ad look familiar. Must be an unintentional error.

                        Typical style for ebay sellers to indicate item location. If any patriotic redneck falls for that you know what they say about fools and their money..
                        "red flag" for me as shipping&taxes from US is killer.

                          Thanks for the thumbs down. YouTube ranks videos based on reactions. Not just on thumbs up reactions.

                              Yes anything but screw clamps for an air hose termination. The unused tail/tang sticking out always gets caught on something and can slice you open pretty quick with any luck at all in some situations. I've been using Pex rings for a number of years and they do work great but they can be a bugger to start depending on hose thickness however the rings do need to go on snug or the rings won't compress enough to make an effective and secure connection.
                              I've used Ruglyde and watered down liquid soap as an effective lubricant. Also I find sticking the fitting into a vise and heating the hose in hot water and then firmly pushing the hose and ring onto the fitting is a more effective way to get the hose onto the barbed fitting.

                              Another good clamp for this type of service is the Oetiker style clamp, not quite as smooth as a Pex ring but close, plus it is a little easier to get onto the right size hose. This last item is key to success as too thin or too thick on both of these types of clamps is a recipe for trouble.

                              One of the best and easiest to use though is the Clamp-Tite stainless safety wire clamp. I made one of these tools a number of years ago and it is not only very durable but also very accommodating in regards to hose size and installation ease. I've even used it in an emergency water line repair when a Pex ring or tool were not available, still working leak free two years later.
