Types of hoses and how to select them

Hoses are commonly used in homes for tasks such as showering, but they can also be used for other purposes such as connecting outdoor air conditioners and gas lines. Hoses make it easy to transport liquids and gasses, but it's important to choose the right type of hose for the job. This article will explain the different types of hoses and how to choose the right one.

What is a hose?

Hoses are items used to transport materials such as liquids, gasses, and powders, and various types of hoses are sold according to material and shape.

Types of hoses and how to select them

When selecting a hose, it is necessary to carefully check the purpose and location of use, and choose one that matches the characteristics of the hose.

Selecting by hose type

Hoses are classified into various types according to their shape.

Air hose


Air hoses are used for transporting gasses such as compressed air and oxygen, and are highly airtight and pressure-resistant. It is used for compressors, etc.

Coil hose


This hose is made of polyurethane or other materials and processed into a curled shape. It has high elasticity and torsion resistance, and can be flexibly moved. It is used for air brushes, machine tools, etc.

Braid hose


Hose with built-in reinforcement. It is 1/3 to 1/5 the weight of a normal rubber hose, but has high oil resistance and pressure resistance.

Resin hose


This hose is made of polyurethane or PVC. They have excellent cold resistance and high chemical resistance, so they are often used for transporting acetic acid and glycerin.

Duct hose


This hose is used for exhaust and dust collection. Some hoses have high heat resistance and chemical resistance depending on the environment in which they are used. They are also used for outdoor units and blowers of air conditioners.

Suction hose


Suction hoses are flexible hoses used for water supply and drainage for upholstery and civil engineering work. Items adaptable to water, oil, powder, etc. are also available.

Rubber hose


This hose is made of synthetic or natural rubber. It has a wide operating temperature range and excellent resistance to friction and aging, but is not used for food products.

Fluorine/silicon hose


Fluorine and silicone hoses have excellent chemical resistance, weather resistance, and corrosion resistance. It has high heat resistance and can be used in a very wide range of temperatures. This hose can be used for a variety of applications.

Hoses for water supply and drainage


This is a general hose made of PVC or polyester fiber. They are inexpensive and frequently used hoses. These are widely used at homes.

Pressure-resistant and abrasion-resistant hoses


These are widely used in shipbuilding and civil engineering.

Oil and fire resistant hoses


This hose is used for transporting oil products such as light oil, kerosene, and heavy oil. It has high oil resistance.

Food hose


This hose is used to convey soft drinks and alcoholic beverages. Most hoses are made of synthetic resin, but some hoses have excellent heat resistance and chemical resistance depending on the material.

Anti-static hose


These hoses contain copper wire and other materials that provide excellent antistatic properties. They are used to transport plastic pellets, calcium carbonate, etc. They are also suitable for use in clean rooms where precision machinery is handled.

Selecting by fluid use

Hoses also vary depending on what type of fluid will flow through it. The fluid used can be water, food, chemicals, oil, air, etc. We suggest choosing a hose based on the characteristics and types of hoses listed above.

Selecting by characteristics

Hoses need to have various characteristics depending on the fluid used. Some fluids can be dangerous if handled incorrectly.

Low odor

Hoses with low or no odor from materials such as polyester or silicone.


It is made of synthetic resin or vinyl chloride and can be expected to have a high conductive effect (anti-static and electrostatic discharge prevention).

Weather resistance

Weather resistance refers to the resistance of materials to deterioration and change during outdoor use. Many products are made of nylon or synthetic resins, and oil resistance and other properties may be added depending on the intended use.

Cold resistance

This is the property of a material that resists cracking and damage caused by low temperatures. Polyurethane and other materials are often used, and can withstand temperatures as low as -30°C.

Chemical resistance

Resistance to chemicals such as alcohol, sodium hydroxide, and ammonia as well as alkaline and acidic fluids. Nylon and synthetic resin materials are available.

Algae resistance

Hoses used outdoors, such as those used for water, can become clogged with algae. By processing the surface of the hose to cut off sunlight, photosynthesis is prevented and the growth of algae in the hose is prevented.

Selecting by inside and outside diameter

The most important factor when purchasing a hose is size. Hose sizes have an inner diameter and an outer diameter, which differ in terms of the size of hose that will fit. For general hoses used for water sprinkling, etc., there is usually a wide range of hose sizes that will fit. Hoses with an inner diameter as small as 2mm, which are used in various machine tools, and hoses with an inner diameter exceeding 100mm, which are used in exhaust ducts, are available in a variety of sizes.

Selecting by material

Although it is not necessary to be concerned about the material of hoses used for water sprinkling in general households, it is necessary to select hose materials strictly depending on the fluid to be used.


Urethane is characterized by good workability, flexibility, and pressure resistance performance. Its properties make it difficult for mold to grow, and it can be used in hot and humid environments. Widely distributed for air piping.


A new material that is lightweight and slippery, and greatly improves hose handling. Widely used in sheet metal, maintenance, tools, etc.


This material has excellent heat resistance and can be bent freely. Mainly used for air conditioning and spot coolers.


A material with excellent resistance to pressure, abrasion, weather, and cold. It is highly versatile and easy to process, making it applicable to a wide range of applications.


Fluoropolymer hoses are often used in scientific and medical fields, semiconductors, etc., and feature excellent chemical resistance and a wide range of operating temperatures.


Widely used as a material for air hoses. Its excellent flexibility makes it easy to be applied to coil hoses, etc., and there are many variations available.


Polypropylene is lightweight and flexible. It is mainly used for air conditioning, ventilation, etc. Some polypropylene products meet the standard criteria for food additives.

Vinyl chloride

Excellent pressure resistance and flexibility. It is characterized by a wide range of adaptability to water, oil, chemicals, powder, and air.

Synthetic rubber

Flexible material available for air, oil, etc.


Hoses are good for collecting and moving fluids that are hard to carry, like air and liquids. There are many kinds of hoses. The fluids they can carry differ, depending on the material and shape. Hoses can be used more effectively by understanding the characteristics of each type.
