I have a great swinging arm boom sprayer for our wash stall, I think made by Farnham. The hose is leaking and needs to be replaced. I can't find a replacement online. I hate to buy a whole new one since the hardware is fine.
If I just buy a 25' 1/2inch garden hose I think I'll have to cut off the ends to be able to thread the hose through the boom tube, and then use a hose repair kit to reattach couplers to which I can attach the nozzle at one end and the female threaded end piece at the other. Which also seems kind of dumb - buying a brand new hose and cutting the ends off.
I've never seen any kind of repair fitting for a hose that ever worked as good, or as long as the original fittings, and didn't decrease the flow rate. I'd avoid cutting it. You can tie a prussik hitch around the hose and tie it to the end of the boom, using a good quality small line, without having to do any hose surgery, or welding.
I bought a Gatorhyde hose when I finally got disgusted with the Flexgen in the wash stall. One thing I didn't anticipate was liking the Nickel plated ends. This winter, I found that they don't leave any taste in your mouth when you blow the hose empty in freezing weather. I found it easier to blow out the 25' hose than handle it to drain it. I didn't used to like doing that with brass ended hoses after doing it once.
