Why Do Hydraulic Hoses Fail?

August 9, 2021

Heavy-duty motorized equipment is built to be tough. But even the toughest materials can lose their strength with prolonged use. So with all the wear and tear your equipment goes through, how can you prevent your hydraulic hoses from failing? First, you must understand what’s causing the issue. 


Seven Reasons Why Hydraulic Hoses Fail


Abrasion

The number one cause of hydraulic hose failure is abrasion. Because these hoses expand and retract during use, they’re constantly moving and are therefore more prone to rubbing. The more the hose rubs, the weaker the materials become. Leaks occur when the outer hose cover is entirely worn away by abrasion, exposing the steel wire reinforcements inside. Fortunately, it’s relatively simple to prevent abrasion on your hydraulic hose. Many manufacturers add plasticizers to the hose cover textile to make it hardier. You can also easily cover any problem areas on your hose with a nylon sleeve or plastic guard.


Routing Issues

Poor routing can expose parts of your hose to increased abrasion. When laying down your hydraulic hose, try to avoid routing it through high-friction or high-temperature areas and pivot points. Be aware of the hose’s minimum bend radius, as excessive bending can cause future issues and eventual hose failure. If you think it will be moving a lot, try using a swivel at the end of it.


Improper Fittings

The fitting, where the hose meets the crimp seal, can also be a frequent source of failure. If the hose bends too closely to the fitting, whether due to the weight of the hose or poorly planned routing, it won’t work correctly. You can fix this with a bend restrictor, a simple plastic product that helps to support the hose around the fitting.


Heat Exposure

High temperatures are not a hydraulic hose’s friend, and when they’re exposed to high heat, they can start to stiffen and lose flexibility. Heat aging, or prolonged exposure to high temps, can cause hoses to splinter from the inside out. If you bend a hose and hear a crack, and it doesn’t bounce back to its usual shape, your hose is experiencing heat aging. Route carefully (see above), and consider buying a heat sleeve for your hose to prevent this.


Installation

Good hose maintenance starts at installation. When they’re installed, the hoses must be cut to size, then thoroughly flushed to clean out any debris that may be left inside. Then the fittings should be crimped, and finally, the hose should be clamped. If you don’t install it correctly, the hose won’t work as it should.


Fluid Compatibility

Not all fluid is compatible with all hoses. Even a high-quality hydraulic hose can start to erode if it’s used with the wrong types of fluid - the fluid can disintegrate the insides of the hose, which slowly start to swell. If a leak occurs, you may have some serious particulate contamination in your hydraulic system.


Erosion

It’s not just incompatible fluid that can damage your hoses. High-velocity fluids rushing through your hose can also start to wear away at its insides. It’s important to choose a hose that is suited to the expected velocity of the fluid inside.

In the world of industrial supply, especially when it comes to hydraulic hoses and fittings, what truly sets a provider apart isn’t just product stock. It’s relationships . At Action Supply, we’ve built our business over four decades on more than inventory: we’ve built it on reliability, responsiveness, and customers trusting us as their go-to partner. The Local Partner Advantage Faster turnaround : Local on-site hose assemblies, quick access to inventory, and the ability to respond when downtime is unacceptable. We work hard to complete your projects with higher quality and fast turn around times. Better communication : You’re dealing with a team that knows your region, your industry, and your challenges—not a generic call center. Inventory you can count on : When your partner manages stock on-site or nearby, you’re less likely to face costly delays. Action Supply offers inventory management services to keep critical parts ready when you need them. Service & Support That Make the Difference Here’s how we add value for our customers year-round: Custom Hose Assemblies On-Site : We don’t just stock hoses; we build them to spec, on-site, matching exact lengths, fittings, and ratings so there’s no guess-work or field fabrication headaches. Consultation & Technical Guidance : Hydraulic systems are complex. We help customers select the right hose, fitting, and coupling for factors like pressure, fluid compatibility, abrasion, and environment. Speed When It Counts : Downtime kills productivity. Having a local partner means faster pick-up, faster delivery, and in many cases, faster problem resolution because we’re already on-site or nearby. Proactive Inventory Planning : From planned maintenance to emergency response, we partner with customers to anticipate needs rather than just react. A true partnership means fewer surprises. A Long-Term View: Why Trust Matters Relationships are built on consistency over time. At Action Supply, our “we’ve worked hard for over 40 years” mindset means we place value on being there for our customers today…and five, ten, twenty years down the road. That long-term presence gives customers the confidence to count on us for standard supply, for emergency replacement, and for growth scale-up. When you know your supply partner will show up, send the right part, understand your system, and back it with service, you’re not just buying hoses or fittings. You’re buying peace of mind. How to Make the Most of Your Supply Partner Here are a few actions to ensure your local supply relationship delivers maximum value: Treat them as part of your team : Share your upcoming projects, shutdown schedules, and maintenance plans with your supply partner. Engage early : Instead of reaching out only when a hose fails, loop in your supply partner during planning or design phases. Keep open communication : Share what matters to you (lead time, budget constraints, delivery windows) and let them tailor service accordingly. Leverage their expertise : Ask questions about alternatives, better materials, and long-term cost savings.  In industrial operations, margins are tight, downtime is costly, and every component matters. At Action Supply, we believe relationships matter because when you win, we win. And when you’re up against the clock, facing tough specs, or dealing with complex hydraulic systems, you’ll appreciate having a partner who’s local, dedicated, and backed by decades of experience.
