Key points of this article
- There are two main points to keep in mind for preventing hose problems.
1. Performing regular inspection and maintenance:
Statutory and voluntary inspections are essential for detecting abnormalities early and preventing problems before they occur.
2. Selecting the right hoses and couplings for the purpose and application:
Choosing products that best match the operating conditions helps prevent problems from ever occurring.
Improvement Tips to Prevent Hose Failures
The main points for improvement are as follows.
1. Performing regular inspection and maintenance
2. Selecting the right hoses and couplings for the purpose and application
Each of these points is explained in detail in the following sections.
1. Performing regular inspection and maintenance
Here’s a quick question for everyone:
Most people recognize the importance of regular inspections for preventing problems.
But from a problem prevention perspective, what is the primary purpose of regular inspections?
A. To improve production schedule progress.
B. To maintain worker safety awareness.
C. To detect abnormalities at an early stage.
The correct answer is C: To detect abnormalities at an early stage.
Regular inspections and maintenance are indispensable for preventing hose problems. They make it possible to identify issues early, prevent them from developing into problems, and resolve them properly.

Inspections are categorized as either statutory or voluntary inspections. Statutory inspections are legally mandated inspections with defined rules on methods, who can perform them, and how often they must be performed. Failure to carry out statutory inspections can result in penalties, so compliance is essential.
Voluntary inspections are set by the company itself, with freely determined items and intervals. While not legally binding, they are highly effective in preventing problems and maintaining quality.
Voluntary inspections can also be further divided into pre-operation and periodic inspections. Pre-operation inspections, performed before starting production to check the equipment, work environment, and raw material conditions, ensure safe and proper operation. Periodic inspections are performed at set intervals to confirm that no problems have developed in production equipment or factory facilities.
When inspecting and maintaining hose piping, check the following points. If any problems are found, we recommend replacing the hose as soon as possible.
• Is the hose clamp loose?
• Is the hose bent or collapsed?
• Is the hose swelling?
• Is there considerable discoloration or exterior damage?
• Has the hose become hardened?
• Are there any problems with the hose mesh?
• Are there any leaks near the couplings? When transporting air, are there any abnormal noises?
（2）Selecting the right hoses and couplings for the purpose and application
Another important step in preventing hose problems is selecting hoses that match the intended purpose and application. There are many types of hoses, including hoses for water, heat resistance, food and beverages, chemicals, and cosmetics. Choosing the most suitable type for the conditions of use is essential.
Using a hose that doesn’t meet the operating conditions can cause problems in machines, products, and piping systems. Accelerated deterioration may also occur, increasing maintenance requirements and replacement frequency, which leads to higher costs.
To choose the best hose for the usage conditions, be sure to check the following.
A. What fluid is being conveyed?
B. What is the pressure?
C. What is the temperature of the fluid?
D. Is the hose for pressure feeding or suction?
E. What size and length are required?
F. What other features should be considered (such as transparency, flexibility, and antistatic properties)?
If it is difficult to determine the best hose based on the above points, or if you would like individual advice, feel free to contact TOYOX directly.

In hose piping systems, a variety of problems can occur, including leaks, disconnections, ruptures, cracks, kinks, hardening, condensation, and sticking caused by static electricity. When such problems occur, they can lead to raw material loss or costly hose replacement—all of which can result in major cost increases. Worker safety is also at risk, making preventive measures essential. In this article, TOYOX’s Hose Adviser Pro explains the recommended countermeasures and improvements for preventing hose problems.
