How to Repair Hydraulic Hose Dripping From a Pressed Fitting

By performing regular inspections and following an effective preventive maintenance program, carefully selecting hose and fittings and keeping everything tidy, you can avoid most hydraulic hose failure issues. Should problems do arise, immediately responding can save both money and downtime.

Always ensure you use the appropriate adapters and couplings when replacing a hydraulic hose, even though it might seem easier to grab another type just to save time. Doing so could have serious repercussions for both yourself and your equipment.

Remove the Fittings

To remove a Propress fitting from a pipe, it's first important to determine the direction it needs to be turned to unclamp it. This is determined by its type - tee/cross fittings open towards the direction of water in a pipe while elbow fittings turn away from it.

Once the direction has been determined, you can rotate and push out the cutter bits on the fitting to free it from its placement on the pipe. This should allow it to come undone.

Before routing it through equipment to its final destination, it is a best practice to cover up its end with a cap or clean cloth to prevent dirt or debris from entering into and damaging its internal components.

After a hose becomes plugged, it is crucial to assess what needs to be removed to facilitate replacing it. This may involve housings, guards, clamps, other hoses and hydraulic cylinders needing removal; additionally it may help label any removed components by number and letter so they can be installed back in their proper places later on.

Cut the Hose

Leaks in hydraulic hoses can be an accident waiting to happen, from fire hazards to environmental contamination. Therefore, whether in the middle of an extensive job or performing regular maintenance checks it's essential that any needed repairs or replacements be made promptly.

Start by relieving any pressure in the system where your hose belongs, making sure any attachments it supports have been lowered or blocked off so they do not collapse and break.

Cut the hose carefully at its end seams to avoid damage to any internal components, then take this opportunity to measure and confirm that its length is appropriate - too long a length could put extra strain on its components, while too short length could result in rupture and failure.

Clean the Ends

Before connecting a hydraulic hose to equipment, its ends must be thoroughly cleaned to avoid contaminants entering your system and potentially causing harm. Furthermore, any damage done through abrasion of the hose itself could prove disastrous.

Cleaning the hose is also of critical importance as contaminants can clog or restrict fluid flow, decreasing efficiency. This could even require costly repairs or replacements of hydraulic components; to prevent this from happening, regular inspections of the hose should be conducted, with all components attached such as housings, guards, clamps, other hoses and hydraulic cylinders cleaned after each use.

Replace the Fittings

Repair can often be the more economical choice when it comes to hydraulic hose replacement. Repair may extend their lifespan, help get out of a jam on the jobsite quickly or save some money in the process.

To address a leak from a pressed fitting, the first step should be removing damaged ends of the hose, cleaning them thoroughly and using a hydraulic hose repair kit to install new ends swage or crimp them onto it. When selecting new replacement ends it's essential that they come from the same manufacturer with matching specifications that ensure optimal fittings.

Dyeing hydraulic fluid, like CITGO's LeakShield AW Hydraulic Oil, to easily spot leaks can speed field repairs and help avoid mistakes that can be costly. Our assembly guide contains further tips for properly assembling hydraulic hoses the first time around.
