When a hose is used to carry oil, certain types of oil may cause the hose to harden rapidly. Because hardened hoses cannot be returned to their original condition and may cause various types of problems, they should be replaced as soon as possible. In this article, Hose Adviser Pro will explain how oil can cause a hose to harden, and how to prevent this from happening. Key points of this article Why are PVC hoses flexible? Polyvinyl chloride (PVC) resin is often used to make general-purpose hoses. PVC resin is hard at room temperature and cannot be bent. However, the PVC resin used in hoses is called “soft PVC […]

Hoses deteriorate and harden with long-term use, making various problems more likely to occur. Therefore, regular inspection, maintenance, and replacement are necessary. This time, Hose Adviser Pro will explain “the concept of hose service life” and “signals for hose replacement and points to note.” Key points of this article Do Hoses Have a Fixed Service Life?

Can you guess why?Take a moment to think about it.Select from among A, B, and C below. A. Because the rate of wear of […]

Hoses can harden over time for a variety of reasons, including the temperature and type of fluid they carry (chemical, oil, etc.), the environment they are used in, and how long they have been in use. Hardened hoses cannot be returned to their original condition, leading to various problems. In this edition, Hose Adviser Pro explains how heat causes hoses to harden and how to prevent problems caused by fluid temperature. Key points of this article A closer look at the secret behind PVC hose flexibility Now, here’s a question for everyone from Hose Adviser Pro. Why do soft PVC hoses harden during use?Select from among A, B, and C […]

Have you ever had a hose come off or leak fluid even though it is installed correctly on the coupling? Leaks and disconnections not only hinder production efficiency but can also lead to loss of raw materials and other production problems. In this article, Hose Adviser Pro explains the main causes of leaks and hose disconnections, along with practical countermeasures. Key points of this article What causes hoses to leak or become disconnected? (1) Hose hardening Why does hose hardening lead to leaks and disconnections?Let’s take a closer look at how hose hardening leads to leaks and disconnections.Select from among A, B, and C below. A. Because fluids flow more […]

Proper operating pressure is one of the key factors in ensuring safe, efficient hose piping. Every hose has a specified pressure range based on the application and conditions of use. Selecting the wrong hose or using the hose at an improper pressure significantly increases the risk of ruptures. In this article, Hose Adviser Pro will explain the importance of ensuring proper operating pressure. Key points of this article What does “proper operating pressure” mean? Let’s start with a question for everyone from Hose Adviser Pro. Why do hoses have a specified “proper operating pressure”?Select from among A, B, and C below. A. To control fluid temperature.B. To ensure safe and […]

Hose bending and collapsing can reduce or block the flow of fluid, resulting in reduced productivity and unexpected accidents. To prevent such problems from arising, it is important to take proper steps to prevent hoses from bending or collapsing. In this article, Hose Adviser PRO will explain the causes of hose bending and collapsing, and how to effectively prevent them. Key points of this article Four causes of hose bending and collapsing 1, Bending the hose beyond its minimum bending radius 2, Heat-induced softening 3, Inability of the hose to support its own weight with fluid inside 4, Using a pressure-feed braided hose for a suction application To learn more […]

We often get questions like, “When is the right time to replace a hose?” Over time, hoses wear out and are more likely to cause problems. That’s why regular inspection, maintenance, and replacement are important. The timing, however, depends on how and where the hose is used. In this edition of Hose Adviser Pro, we’ll go over how to think about a hose’s service life and review key checkpoints to help you know when it’s time to replace your hose. Key points of this article Do hoses have a fixed service life? Many customers ask us about the expected service life of Toyox hoses. But in fact, our hoses do […]

Have you ever had an issue with odor transfer when using hoses to carry raw material fluids? One reason why odors remain in fluids carried by hoses is the odor coming from the hoses themselves. Not addressing such a problem can result in products becoming defective and lead to even bigger problems. Choosing the right type of hose is essential when manufacturing products where odor is a problem. In this article, Hose Adviser Pro will introduce types of low-odor hoses and how to select the right one for your application. Key points of this article Hose material properties and suitable usage environments Let’s start with a question for everyone from […]
