Key points of this article
- There are four main 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 non-suction hose for a suction application - The best way to prevent these kinds of problems is to select a hose that is resistant to bending and collapsing and specifically designed for the intended application.

Two countermeasures to prevent hose bending and collapsing
There are two main ways to prevent hose bending and collapsing caused by the four factors above.
But first, here’s a quick question for everyone from Hose Adviser PRO.
Which of the following is not a suitable method to prevent hose bending?
Select from among A, B, and C below.
A. Select a hose that is resistant to bending and collapsing.Select a hose that is resistant to bending and collapsing.
B. Select the right hose for the application.
C. Replace the hose every month.
The correct answer is C. Replace the hose every month.
Hose replacement timing varies depending on the type of hose and the conditions of use, so there is no general rule for replacing the hose every month.
Both A and B are suitable methods to prevent hose bending and collapsing.
The methods are explained in order below.
1．Select the right hose for the application.
The conditions of use span a wide range and include the type and temperature of the fluid carried by the hose, as well as the pressure (positive and negative pressure). When the hose is not suitable for the conditions of use, the hose may soften or deteriorate rapidly, making bending and collapsing more likely. When the hose is used for suction, hose collapse should be prevented by using a hose that is designed to withstand suction, and which includes shape retention using a metal or resin coil.
2. Select a hose that is resistant to bending and collapsing.
Hoses that are resistant to bending and collapsing include shape-retaining types that are reinforced by a metal or resin coil, as well as braided types (not suitable for suction applications) that are resistant to bending and collapsing while retaining flexibility and pressure resistance. These kinds of hoses can be used with tight bends in narrow locations such as inside equipment or in narrow equipment piping spaces.
TOYOX offers a variety of hoses that retain their shape to help prevent bending and collapsing. Check the product list below to see the best hose for specific usage conditions.

Shape-retaining hoses resistant to bending and collapsing
Some braided hoses are also less prone to bending and collapsing than others due to the braiding method of the reinforcement thread or the thread material used. Such models are ideal for use in tight spaces.

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.
