Hydraulic Hose Repair

I'm trying to repair a hydraulic hose for one of my stabalizing jacks. It's lippert system and I have the new fitting but don't know what crimper tool to use. There is enough hose for me to cut the existing one and attach the new fitting. Trying to avoid removing the entire hose. It's the rear jack. Has anyone had to do this?

Those crimpers are extremely expensive. I'd go to NAPA where most of them make replacement hoses. They might do it for you. If not call hydraulic repair or truck mechanics. They will have the tool.

My question is why are you repairing your hydraulic hose? Did you find something wrong with it such as a blister or bubble? Or something else? If so, then you need to change the whole hose. I only ask because I am in the middle of changing all my hoses due to severe blistering or bubbles from failing inner liner. Leveler system pumps produce high pressure so you may want to have a hydraulic shop fix it so it won't have a chance to fail and create a mess. Hope it works out for you.

Not sure on the stabilizer jack but my HWH hydraulic slides required a special 6000psi hose that is not available at most auto parts stores or hydraulic shops. That said I don’t think you are going to find a tool to crimp your lines to be a common rental tool. Most likely you will need to find a shop with a portable hydraulic hose repair system. My recommendation would be to remove the hose and have a new replacement one made. Normally if a hose fails it is either at the end of life or been snagged on something. Also you may want to check to be sure the hoses are not a balanced system, if it is the hose are specked to specific length. I know again my HWH hydraulic slide system was that way. I wouldn’t particularly think leveling jacks are but they may be. I would check with Lippert industries regarding this. It was a big deal on my slides.

Also you may need to consider the condition and replacement of all your hoses.

Something I ran into when trying to repair an end on steering hydraulic hose is most places do not want to replace a fitting only on used hose. Even manufacturers have warnings about it. I ended up buying an expensive crimper and the die set to match fitting and hose. Made the repair myself.

We had a hydraulic hose fail due to welding too close to it while fixing the spring hangers.

Ours only gave to be rated to 3000 psi (we are a fifth wheel). We knew replacing the hose was our only option. Decided to replace the other side as well. We have a hydraulic shop up from us and they have all the parts. We pick up our new one Friday.

We make hydraulic hoses in my auto machine shop. I will not install a fitting on a used hose. It will never be satisfactory. The machines used to install the fittings are expensive and not all of them will work on all brands of fittings.
Your best bet would be to remove the hose and take it to a shop and have a new hose made up if the shop has the correct fittings. There are hundreds of sizes and types of fittings in use today. No one shop could possibly be able to afford to stock them all. Close isn't close enough.
You would never be able to apply the pressure required to crimp a fitting to a high pressure hydraulic hose with a hand held tool.
A farm equipment store or dealer might have a hose which would work for you. Be sure the hose has the correct pressure rating or higher. Unless it's absolutely necessary avoid adapters. The less connections you have the less chance for a leak.

look for or ask for "reusable" high pressure fitting also called "field applied" sometimes it might work out where you get one reusable fitting for your existing hose... then get a small whip hose made with the proper end fitting needed to connect up to your jack.. with a fitting on the other end that will mate to you field applied fitting.... we do this all the time on heavy equipment.
