Key points of this article
- Although hoses are commonly insulated with polyethylene foam (PEF), because retrofitting can be difficult in some locations, preemptive measures are essential.
- Using insulated hoses and dedicated couplings eliminates the need to install separate insulation and can enhance work efficiency.
- Because condensation is most likely to occur during rainy seasons and in summer, it is best to take precautions in advance.
Hose insulation method 1 — Wrapping with polyethylene foam (PEF)
Let’s start with a question for everyone from Hose Adviser PRO.
What is a common method to prevent condensation on hoses?Select from among A, B, and C below.
A. Insulating the hose surface
B. Increasing humidity in the air
C. Increasing the temperature around the hose
The correct answer is A. Insulating the hose surface.
One common method of insulating hoses is to cover them with a sheet-like insulating material called polyethylene foam (PEF). In this method, insulation is performed by tightly wrapping and gluing PEF material around the hose so that there are no gaps. In addition, because condensation can also occur at the couplings, the polyethylene foam insulation must also be wrapped tightly around each coupling with no gaps. This can prevent condensation from forming on the hoses and couplings.
However, although insulating short and easily accessible hoses can be easy, adding insulation to longer hoses and less-accessible hoses in cramped equipment can be expensive and time-consuming. There may also be areas in some locations that cannot be completely insulated. It is also important to remember that condensation countermeasures using PEF should be implemented in advance.
Hose insulation method 2 — Selecting a pre-insulated hose
Some hoses come pre-coated with insulation material to prevent condensation. Using such hoses eliminates the need to wrap and tape insulation such as PEF around hoses. Also, using dedicated couplings and insulated coupling covers provided by the hose manufacturer to eliminate gaps will make preventing condensation on the couplings easier. Such insulated hoses and dedicated couplings make connecting hoses that prevent condensation quick and easy, similar to connecting a regular hose. Such hoses do not require any additional insulation-related work.
Hose with integrated insulation Insulation cover for couplings
It is important to take measures against condensation before it occurs during periods when it is likely to occur, such as during rainy seasons or in summer. Due to the wide variety of cooling fluids used, be sure to also check the fluids and conditions supported by the insulated hose and dedicated couplings before use.
Toyox offers a range of hoses with integrated insulation and dedicated couplings to prevent condensation.
Because these hoses not only eliminate the need for insulation, but also improve work efficiency while helping to reduce the risk of problems, why not give them a try?

Condensation tends to form on the surface of hoses carrying low-temperature fluids, and the dripping water it causes can result in problems. One way to prevent or reduce condensation is to minimize the temperature difference between the hose and the surroundings and to reduce the ambient humidity. However, because using air conditioning equipment to adjust the temperature and humidity inside the factory or around hoses can be expensive, it is common to insulate the surface of hoses. In this article, Hose Adviser PRO will describe hose insulation methods.
