Silicone Hose Pressure Rating is a critical factor in many engineering applications. Whether you are in the automotive industry, medical device manufacturing, or the food processing industry, you may need to use silicone hose. When selecting and using silicone hose, it is critical to understand its pressure rating to help ensure the safety and performance of your system. In this article, we’ll take an in-depth look at silicone hose pressure ratings to help you better understand their importance and how to properly select and use silicone hose.

Factors to consider when choosing a pressure rating for silicone hose

The pressure rating of a silicone hose is the maximum working pressure it can withstand. This is a critical parameter as it determines whether the silicone hose is suitable for a particular application. The pressure rating of silicone hose is usually expressed in units of “psi” (pounds per square inch) or “bar” (bar).
When selecting silicone hose, you need to consider the following factors to determine the pressure rating you need:

  1. Application
    Different applications may require different pressure ratings. For example, automotive engine cooling systems often require silicone hoses that can withstand high pressures, while laboratory equipment may have relatively low requirements.
  2. Temperature
    Operating temperature also has an effect on the pressure rating of silicone hose. In high temperature environments, silicone hoses may require higher pressure ratings to maintain their performance and safety.
  3. Fluid properties
    The type and nature of the fluid being transported can also affect silicone hose selection. Some fluids may be corrosive to silicone hoses and require special chemical resistance.
  4. Piping layout
    The design and layout of the piping will also affect the pressure rating requirements of the silicone hose. Complex piping layouts may require higher bending performance.

How to choose the right pressure rating for silicone hose

Choosing the right pressure rating for the silicone hose is critical. Here are some steps to help you choose the right silicone hose:

  1. Determine the working pressure
    First, you need to determine the operating pressure range for your application. This is usually the starting point for your silicone hose selection. Make sure you take into account the maximum peaks in working pressure.
  2. Consider operating temperature
    The operating temperature has a significant impact on the performance of silicone hoses. Ensure that the hose you select is able to work safely within the required temperature range. If the operating temperature is high, it may be necessary to select a silicone hose with higher temperature resistance.
  3. Understanding fluid properties
    Understand the nature of the fluid being transported to ensure that the silicone hose you choose is chemically resistant to prevent the fluid from corroding or damaging the hose.
  4. Consider the piping layout
    If there is a complex piping layout in the application or if the silicone hose needs to be bent to fit a particular shape, make sure that you select a hose with excellent bending properties.
  5. Check the manufacturer’s specification sheet
    Manufacturers of silicone hose often provide detailed specification sheets for their products, including pressure ratings, temperature ranges and suitability. Be sure to check these specification sheets to ensure that the hose you select meets your requirements.


Silicone hose pressure ratings are critical for many projects and applications. Selecting the right silicone hoses for the application, taking into account factors such as working pressure, temperature, fluid properties and piping layout is essential. The properties of silicone hose, such as high temperature resistance, electrical insulation and chemical resistance, make it useful in a wide range of applications. It is of utmost importance that silicone hoses are regularly maintained and serviced to ensure their performance and safety.
