Usually, once a hydraulic hose is damaged, replacing it with a new one is the best course of action. But if, in some cases, the hose must be temporarily repaired, here are steps you can take:

Repairing broken hydraulic hoses is a task that needs to be handled with care, as hydraulic systems involve high-pressure fluids, which can be dangerous if not handled properly.

How to repair and fix a broken hose

  1. Shut down the system: Before making any repairs, always verify that the hydraulic system is shut off and that no hydraulic pressure is present. Hydraulic systems can operate at very high pressures, posing a serious risk to personal safety.
  2. Before you start: Get a repair kit for your hydraulic system, usually including seal rings, bushings, and fasteners. Make sure these fittings are compatible with your hydraulic system.
  3. Cleaning and Trimming: Using proper tools and methods, trim off the ends of the damaged section of hose, making sure that the trimmed edges are clean and free from cuts and cracks.
  4. To install the seal rings and sleeves: Slide the seal rings provided over the ends of the hose, making sure that the seal rings completely cover the hose break. Next, install the sleeve, making sure the sleeve fits the hose completely.
  5. Fastening Fittings: Use matching fasteners (bolts or clamps) to secure the sleeve and hose ends together. Make sure the fasteners are tightened evenly, not too tight or too loose.
  6. Test: After the repair, do a close inspection of the hydraulic system and make sure there are no leaks. Then you can slowly increase the hydraulic pressure to check whether the hose repair is reliable, there is no leakage or other problems.
  7. Temporary Fixes: It is important to emphasize that this fix should be considered temporary and should only be used as a temporary fix in an emergency. Replace the hydraulic hose with a new one as soon as possible after repairing to ensure the safe and stable operation of the hydraulic system.

Important reminder:
Due to the complexity of the hydraulic system and the presence of high-pressure fluids, non-professionals are best not to attempt to repair hydraulic hoses. Any incorrect repairs could result in serious accidents and injuries. The safest and most reliable way is to replace the hydraulic hose with a new one, or have it repaired by a professional technician.
