Just getting around to installing a DC in my shop. Working on ten things at once. I have 50 ft of 4" flex hose that came with the DC. Was looking at flex to PVC adapters, $10 each with 2 for every machine and a couple for the DC and maybe the Thien top hat. I'm looking at $200 for adapters.

Instead, I made a die and made some for the cost of 4" of PVC pipe. At $2.10 a foot, I have 70¢ in each adapter. It takes longer to prep the nipples than to swedge the pipe.

The die is 3 layers of plywood cut out with a 4" hole saw with ⅜" round over. I hit each nipple with dry silicone spray and hit it with the heat gun for 90 seconds.

The first swedge did collapse and kink. I ran a rotary sander hooked on my drill to taper the top a bit. Works great 👍

Great work and a nice swaging die. It sure beats factory adaptors and almost any price.

thanks wnt. i can't claim the idea as my own. i had glued up the die the night before, with intensions of cutting it in half, heating the pipe and clamping it in the vise. surfing youtube gave me this video, i just ran the round over bit and sanded a little to my die. my die is a lot deeper than the guy in the video, maybe 3x the swedge.

easy peasy (y)


fwiw... swedge and swag have the same definition, as a pipe fitter/welder i learned swedge

I got 50+ft of hose with this DC, the 2 long hoses with steel wire go on the swedged nipples fine. The ten ft hose has plastic reinforcement 'wire' in it that won't fit on anything.
In another thread I mentioned that hose adapter fittings vary from tool to tool. Now I have 2 different size 4" hose 🤦‍♂️
