Connection fittings:
Connection fittings are located at both ends of the flexible hose. They allow the hose to connect to other systems or components. Common types of connection fittings include threaded ends, welding ends, and flange ends.
Pressure and temperature rating:
Each flexible hose has a pressure and temperature rating. This indicates the maximum pressure and temperature the hose can safely withstand. It is essential to choose a flexible hose with appropriate ratings for specific applications to avoid accidents.
Coilability:
Flexible hoses are highly coiling and can be bent and twisted into different shapes without breaking. This feature allows for easy routing around obstacles in tight spaces.
Leakage prevention:
Flexible hoses are designed to prevent leaks. They have built-in washers and O-rings that create a tight seal at connections. This prevents the flow of liquids or gases from escaping.
Anti-kinking feature:
Some flexible hoses have an anti-kinking feature that prevents the hose from being damaged when it is bent at a sharp angle. This feature is common in plumbing and irrigation hoses.
Flexible hoses have various applications across different industries and sectors. Here are some common scenarios where flexible hoses are used:

Flexible hose fittings come in various materials, and each has its unique properties. This allows for an extensive range of applications. However, some options are better suited for particular tasks than others. Here is a comprehensive guide on choosing the right flexible hose:
Application
The first step involves determining the intended purpose of the flexible hose. This includes identifying the environment where it will be used, such as; whether it will be exposed to high or low temperatures, chemicals, pressure, or weather elements like moisture and humidity. This guides the selection process by narrowing down options to those suitable for specific conditions. For example, if the hose will be used in an area with sharp objects or extreme temperatures, a stainless steel braided hose may be ideal due to its durability and flexibility.
Compatibility of the Fluid
Another important consideration is the type of fluid that will pass through the hose. This includes; the temperature, pressure, and chemical composition of the fluid. This is important because some materials may react with certain fluids, causing leaks or safety hazards. For example, if the fluid is highly corrosive, a hose material like polypropylene may be preferred since it can withstand the fluid's corrosive nature.
Pressure and Temperature
It is important to check the maximum pressure and temperature of the application area. Most flexible hoses are rated for specific pressure and temperature ranges. Exceeding these limits can cause the hose to fail catastrophically. Therefore, it is important to choose a hose that can handle the required pressure and temperature.
Hose Material
Flexible hoses are made from different materials, such as rubber, PVC, silicone, and various metals. Each material has unique properties that make it ideal for certain applications. For example, rubber hoses are ideal for water applications, while silicone flexible hoses are better suited for extreme temperature applications.
Diameter and Length
It is also important to consider the diameter and length of the flexible hose. This ensures it fits perfectly into the system it is intended to be installed. A hose that is too long may cause a drop in pressure, while one that is too short may be under tension and at risk of bursting. Additionally, the diameter needs to be compatible with the fittings to ensure no leaks occur.
