Common causes of hose failure and how to prevent them

|
3 min

In real working conditions, hoses rarely fail without a reason. In most cases, it is a combination of factors:  wrong selection, unsuitable working conditions, or incorrect installation. The result is always the same: downtime, extra costs, and risk for the entire system.

The good news is that these issues are rarely random. When the main causes are understood, most of them can be prevented early on.

1. Choosing the wrong hose for the application

One of the most common reasons for failure is using a hose for a job it was not designed for. At first, everything may seem fine, but over time the material starts to wear out, lose its shape, or react with the media. A typical example is using a standard water hose to transfer fertilizers or abrasive mixtures. The inner layer is not designed for this type of use and begins to wear or get damaged.

How to prevent it:

Start with the actual working conditions what is flowing through the hose, whether there are abrasive particles, what the pressure is, and how often it is used. It is not just about whether the hose works, but whether it will last. For fertilizers, slurry, or abrasive materials, a hose like 015S is a better choice. Its smooth inner surface helps reduce buildup, improves flow, and limits wear over time.

2. Wear caused by abrasion

In many cases, damage starts from the outside. Constant contact with rough surfaces like concrete, metal, or soil slowly wears down the outer layer. This weakens the hose and eventually leads to leaks or failure. This type of damage often goes unnoticed until it becomes serious.

How to prevent it:

The hose should be properly positioned and fixed so it does not move freely. Avoid sharp edges and, where needed, use protection or support in high-contact areas. In construction sites or heavy-duty environments, a solution like 010SSZ provides better reliability. It is designed to handle abrasive conditions, heavy loads, and demanding use.

3. Excessive bending and kinking

Every hose has a maximum bending radius. When this is exceeded, the hose can kink, restricting flow and putting stress on its structure. Over time, this leads to weak points and failure. This often happens due to poor routing or limited space.

How to prevent it:

Install the hose so it follows a natural path, without sharp bends. If needed, use the right fittings or connectors to guide the flow properly. In pump systems, spiral-reinforced hoses like 011N help maintain shape and prevent collapse under suction.

4.Operating above the pressure limits

When the pressure exceeds the hose’s limits, it can swell, leak, or burst. The issue is often not constant pressure, but sudden spikes in the system.

How to prevent it:

Always choose a hose with a safety margin above the actual working pressure. It is also important to consider how the system behaves during start and stop cycles. For pressurized systems, braided hoses like 330M, 340MB, 342MB and 380MR provide stability thanks to their reinforced construction.

5.Temperature and environmental conditions

Temperature has a direct effect on hose performance. In low temperatures, the material becomes stiff and more likely to crack. In high temperatures, it ages faster and loses strength. This factor is often underestimated, especially in seasonal use.

How to prevent it:

Select a hose that matches the real temperature range of the application, not just standard conditions. For cold environments, 008S and 011S remain flexible, while in more demanding conditions 010SSZ can operate reliably even at very low temperatures.

6.Chemical incompatibility

If the hose material is not compatible with the media, it can swell, soften, or crack over time. This usually happens gradually and is not immediately visible.

How to prevent it:

Always check what will pass through the hose, not just the type of media, but also its concentration and temperature. For food applications, 501N is suitable for handling milk and dairy products safely. When visual flow control is needed, 320N and 600N allow easy inspection and help maintain hygiene standards.

7.Incorrect installation

Even the right hose can fail quickly if installed incorrectly. Twisting, overstretching, or using the wrong fittings creates stress that shortens its lifespan.

How to prevent it:

Install the hose without twisting, allow enough length, and use the correct fittings. The hose should have enough freedom to move without being under tension. When a hose is properly selected, correctly installed, and used within its limits, it performs reliably over time.

At Plexistab, we believe our role is not just to supply products, but to help customers make the right choice from the beginning based on real working conditions. Because the right hose is not defined by how it looks, but by how well it performs in your system.
