Making hoses with regular press

[racerboy832]

I was talking to my dad and he said the guy years ago that made his Hydraulic lines just had some dies and a 20 ton press to crimp them. He said he never had a problem. Any seen this or where you can buy the dies. I bought him an old ford backhoe and it's going to need all the lines.

I don't think a universal die set would crimp all the various hoses and fittings available today.

Most all the manufactures say to only use their hoses and crimpers for quality work.

I have had a hoses push off the crimp. It was made up by a hyd service guy.

a press would work, IF you had the correct collets & dies for the fittings & hose.

You can press off Caterpillars hose fittings and repress them ontolines with a regular press if needed. On the servicetruck I often keep make up fittings that screw on to hoses without a press.

they do make crimpers with micrometer settings and catalogues with conversion factors for different hoses and fittings. however unless your going into the hose business jj's suggestion of using a manufacturers parts and crimpers is good advice. the old guys use to set up the old fittings in their dies measure the height of the stack and then make up the new hose with a press and those measurements. they were also using lower pressures back then. nowadays shops have to be mindful of what they are making (insurance claims and all). reuseables are a good alternative to not having a press and dies and can be cheaper and handier in the long run.

I use the Gates PC707 (I have two).....Power Crimp 707 hydraulic hose crimper | Gates Corporation

this crimper is adaptable for all types of fittings with the digital/micrometer settings on the side switch that can be tweeked to crimp anything as long as I have the proper crimp dia specs.....Not as user friendly but does more work and can reproduce any brand hose crimp

That said, most hose manufaturers make crimp machines with the dies to match a peticular size hose......for the proper crimp you need a set of dies to match whatever hose/fittings you want, the dies just squeeze and bottom out for a full crimp........that's where the press comes into play, if you have the proper dies to match the hose/fittings then all you need to do is press them all the way bottomed out in the press cone.....DONE

The press setup in the video is OK assuming you only use weatherhead hose/fittings with matching dies

a friend of mine uses that rig and it works well for him. gates hoses are an old company and their hoses have a good flexibility. flexdraulics is also a good product and is geared towards agriculture.

I purchased a Hosecomatic hyd kit with fewer parts several years ago. I don't know that I will be making up hose assembly's based on some comments about tolerances and so forth.

Anybody use these manual hyd kits?

It appears that if you use the stated hose and their fittings, and use the beading tool and use some good calipers, you might get some good tight hose assembly.

What would you hose guys do when a customer brings in a hose and just wants a fitting replaced, do you make an educated guess about the crimp, and will you guarantee the repair.
