How Important are Hydraulic Hoses for Your Machines?
Hydraulic hoses are really important for many machines. They carry fluid under high pressure to make things move. If these hoses fail, it can cause big problems. Machines might stop working, people could get hurt, and it can cost a lot of money to fix.
Hydraulic Hose Failure Types
Abrasion and Wear
One common problem is abrasion and wear. This happens when the outside of the hose rubs against other parts of the machine or rough surfaces. Over time, this rubbing wears away the protective cover of the hose. If the cover wears down too much, the inner parts of the hose can get damaged, leading to leaks or bursts.
Prevention:
- Ensure hoses are the correct length and diameter for the application.
- Route hoses according to the manufacturer’s specifications, using provided hangars and brackets.
- Replace any missing chaffing guards.
- Use protective sleeves, wraps, or guards made of materials like nylon, plastic, or steel to shield hoses from rubbing against other components, sharp edges, or abrasive surfaces.
- Bundle hoses that flex in the same direction together using clamps, ties, or spring guards to prevent hose-on-hose abrasion.
- Avoid routing hoses through areas with high movement or vibration without proper clearance and support.
- Regularly inspect hoses for signs of wear, such as scuffs, cuts, or thinning of the outer cover. Replace hoses promptly if damage is detected.
How Fleurieu Hydraulics Can Help:
- Assess the application and recommend the most suitable abrasion-resistant hoses and protective measures.
- Properly route and clamp hoses to minimise abrasion points, ensuring correct installation according to manufacturer guidelines.
- Install protective sleeves, wraps, or guards correctly for maximum effectiveness.
- Conduct regular inspections to identify potential abrasion issues early and advise on replacement schedules.
Excessive Pressure and Bursts
Prevention
- Select hoses with a working pressure rating that safely exceeds the hydraulic system’s maximum operating pressure, including potential pressure surges.
- Install pressure relief valves to manage and prevent pressure spikes within the system.
- Consider using spiral wire-reinforced hoses instead of wire braid-reinforced hoses in systems with recurring pressure surges.
- Ensure the hydraulic system is designed and calibrated to operate within the recommended pressure range. Regularly inspect pressure gauges and relief valves.
- Avoid operating hydraulic systems beyond their design limits.
How Fleurieu Hydraulics Can Help:
- Evaluate the hydraulic system’s pressure requirements and recommend hoses with the appropriate pressure rating.
- Install and calibrate pressure relief valves to protect the system from over-pressurisation.
- Diagnose and address any system malfunctions that could be causing excessive pressure or surges.
Leaks
Prevention:
- Conduct regular visual and physical inspections of hoses and fittings for signs of wear, cracks, damage, or fluid accumulation.
- Ensure fittings are correctly tightened to the manufacturer’s specifications using a torque wrench. Avoid over-tightening or under-tightening.
- Use high-quality hoses and fittings that are compatible with the hydraulic fluid and the system’s pressure and temperature requirements.
- Replace worn seals and O-rings promptly.
- Properly clean and inspect components before assembly to prevent contamination that can lead to leaks.
- Monitor hose flexibility; hoses that have hardened or become excessively rigid are more prone to cracking and leaks.
How Fleurieu Hydraulics Can Help:
- Identify the source of leaks through thorough inspection and pressure testing.
- Replace damaged hoses, worn seals, and faulty fittings with the correct components.
- Ensure proper assembly and tightening of fittings according to manufacturer guidelines.

- Use hoses of the appropriate length to prevent stretching or forcing into tight bends. Allow for some slack to accommodate movement and pressure changes.
- Secure hoses with clamps and brackets to prevent unwanted movement and maintain proper routing.
- Consider using 45-degree or 90-degree fittings to achieve efficient routing without excessive bending.
- Incorporate hose bend restrictors or springs near fittings to reduce stress at the connection points.
How Fleurieu Hydraulics Can Help:
- Design and implement proper hose routing that adheres to minimum bend radius requirements.
- Install hoses with the correct fittings and length to avoid kinking and bending issues.
- Provide and install hose clamps, brackets, and bend restrictors to support hoses and prevent kinking.
Heat Degradation and Aging
Prevention:
- Select hoses that are rated for the specific operating temperature range of the hydraulic system and the environment.
- Route hoses away from heat sources such as engines, exhaust manifolds, or high-temperature processes.
- Use heat shields or protective sleeves made of heat-resistant materials like silicone rubber or fiberglass to insulate hoses from extreme temperatures.
- Ensure proper ventilation around hydraulic hoses to dissipate heat.
- Implement a regular hose replacement schedule based on the hose’s age, service hours, and manufacturer recommendations, as hoses degrade over time.
How Fleurieu Hydraulics Can Help:
- Assess the operating environment and recommend hoses with appropriate temperature ratings and heat protection.
- Advise on optimal hose routing to minimise heat exposure.
- Install heat shields and protective sleeves correctly.
- Establish preventative maintenance schedules for hose replacement based on industry best practices and specific application requirements.
Improper Installation and Assembly
Prevention:
- Follow the manufacturer’s guidelines and industry best practices for hose assembly and installation meticulously.
- Use the correct fittings that are compatible with the hose type and size.
- Ensure proper crimping of fittings using calibrated crimping tools and the correct crimp specifications.
- Tighten fittings to the recommended torque values using a calibrated torque wrench.
- Cut hoses squarely and clean them thoroughly to remove any debris before installing fittings.

- Provide training on proper hose assembly and installation procedures to prevent future issues.
Wrong Type of Fluid Use
Prevention:
- Always use the hydraulic fluid recommended by the equipment and hose manufacturer.
- Verify the compatibility of the hydraulic fluid with the hose’s inner tube and seal materials to prevent degradation, swelling, or cracking.
- Store and handle hydraulic fluids properly to prevent contamination or mixing of different fluids.
How Fleurieu Hydraulics Can Help:
- Recommend the correct hydraulic fluid based on the system requirements and hose material compatibility.
- Identify and address any issues caused by using incompatible fluids.
- Provide guidance on proper fluid storage and handling to maintain fluid quality.
External Damage
Finally, external damage can cause hoses to break. Things like cuts, punctures, or crushing can damage the hose. Even if the outer cover is damaged, the inner parts of the hose might be affected.
Prevention:
- Protect hoses from impact, cuts, punctures, and crushing by using protective sleeves, guards, or wraps.
- Route hoses away from areas where they are likely to be struck by objects or subjected to heavy loads.
- Use hose guards or spiral wraps in areas prone to physical damage.

FREQUENTLY ASKED QUESTIONS (FAQ)
1. How does a hydraulic hose breakdown typically affect the operation and productivity of the equipment or machinery it's part of?
When a hydraulic hose breaks down, the machine usually can’t work properly or might stop working altogether. This is because the hose carries the high-pressure fluid that powers the machine’s movements and functions. If the hose fails, the fluid leaks out, and the machine loses its power, leading to slower operation, reduced efficiency, or complete stoppage. This results in lost productivity and delays in work.
2. What are the potential safety hazards associated with a sudden hydraulic hose failure?
A sudden hose failure can be very dangerous. The high-pressure hydraulic fluid can spray out with a lot of force and can cause serious injuries if it hits someone. This fluid can also be very hot and can cause burns. Additionally, if a hose breaks on equipment that’s lifting something, the load could suddenly drop, posing a severe crushing hazard. Leaking hydraulic fluid can also create slippery surfaces, increasing the risk of falls.
3. Can a hydraulic hose breakdown lead to environmental issues, and if so, what are they?
Yes, hydraulic hose breakdowns can cause environmental problems. Hydraulic fluid leaks can contaminate the soil and nearby water sources. This can harm plants, animals, and the overall ecosystem. Cleaning up spilled hydraulic fluid can also be costly and time-consuming.
4. What are the common financial consequences of a hydraulic hose failure, including repair costs and downtime?
Hydraulic hose failures can lead to significant financial losses. The immediate costs include the expense of replacing the damaged hose and possibly other damaged components. However, the biggest cost is often the downtime – the time the equipment is out of service and not generating income. This can lead to missed deadlines, reduced productivity, and higher operational costs. Emergency repairs, especially if needed after hours, can also be much more expensive than planned maintenance.
5. Beyond immediate operational stoppage, are there any longer-term impacts on other components or the overall lifespan of the hydraulic system due to a hose failure?
Yes, a hose failure can have longer-term effects. If a hose bursts and the system loses a lot of fluid, it can cause other components like the hydraulic pump to overheat and potentially fail due to lack of lubrication. Contamination can also enter the system through a failed hose, leading to wear and tear on other parts and reducing the overall lifespan of the entire hydraulic system.
6. What kind of secondary failures or damage to surrounding equipment can be caused by a hydraulic hose rupture?
When a hydraulic hose ruptures, the high-pressure spray of fluid can damage nearby electrical components, leading to short circuits or fires. The force of the burst can also potentially damage other hoses or adjacent machinery parts. If the failed hose was supporting a component under pressure, like a cylinder, the sudden loss of pressure could cause that component to collapse or move unexpectedly, damaging itself or surrounding structures.
7. How can the failure of a hydraulic hose impact project timelines or service delivery in different industries?
In industries where machinery relies heavily on hydraulics, like construction, mining, agriculture, and transportation, a hose failure can cause significant delays. If a critical piece of equipment is out of service due to a broken hose, it can halt operations, disrupt project schedules, and lead to penalties for late completion. For services that depend on operational vehicles or machinery, like waste management or transport, a hydraulic hose failure can directly impact their ability to deliver services on time, leading to customer dissatisfaction and potential financial repercussions.
8. Why it is important to call a professional to help for these types of hydraulic hose breakdowns?
Dealing with hydraulic systems and hose failures can be complex and dangerous. Professionals have the specialised knowledge, tools, and experience to accurately diagnose the cause of the breakdown and perform repairs safely and effectively. They can ensure that the correct type of hose and fittings are used for the specific application and pressure requirements. Improper repairs or using the wrong components can lead to further failures, potential injuries, and increased costs in the long run.
Professionals also follow safety protocols to prevent injuries from high-pressure fluids and ensure the hydraulic system is functioning correctly after the repair. While some minor maintenance might be possible for trained personnel, significant hydraulic repairs, especially hose replacements, often require professional expertise.
