Compatibility: This works on the Harbor Freight air/hydraulic cylinder PN 56215, and also on the Northern Tool Cylinder #46200. Choose the correct application please.
This adapts your tubing bender so that the pins will be supported well enough to bend 1.75x.250 DOM tube! or solid HR round bar! Great for other heavy wall and high strength materials too. This is ONLY for air/hydraulic applications. It is not compatible and completely unnecessary on our electric/hydraulic powered machines. It also has the benefit of making your machine bend 94 degrees in one ram cycle so you can bend a 90 and spring back in many cases without re-pinning the ram. Without this kit the machine only bends to 88 degrees gross.
IMPORTANT! – An additional pressure die is required for HD applications, and you must order them separately. One for each tube size that you want HD capacity in. See “ordering example” tab for more detail on how to order. You can use any 2 pressure dies you want for HD bending, 2 rollers, 2 standard pressure dies, one of each, etc.. For a complete range of wall thicknesses that require an HD kit, please visit our Wall Thickness Chart (LINK).
Why would I want this: You must use this on ANY material that is said to require it in our master wall thickness capacity chart. If you do not, you will bend at least 1 pin in the machine, and be responsible for the damage. This also makes the ram 1.25″ longer, increasing machine travel by several degrees (which you may want).
Why wouldn’t I want this: If you are only bending .120 wall DOM tube and are happy with your ram travel length, this will not make the machine work any better or last longer. If you are buying the M600 HD or xHD it already comes with this.
Note: This must be temporarily removed from your machine while using a Thin Wall Attachment (TWA) if equipped (the TWA is discontinued). This also works on the old HR ram, PN 94562.
