When selecting the appropriate silicone hose for your project, there are several key factors to consider. Silicone hoses are widely used in various industrial and commercial applications due to their excellent heat resistance, chemical inertness, and flexibility. This article will delve into how to choose the right silicone hose based on project requirements and specific application scenarios.

7 Steps to Choosing Silicone Hoses

1. Size

The size of the hose needs to be precise to ensure maximum flow velocity for internal transport materials. Too slow flow can lead to decreased system performance, while excessive flow can create additional pressure, potentially damaging the system and causing leaks. Determining the most suitable hose size involves considering factors such as:

  • Inner diameter
  • Outer diameter
  • Connection dimensions
  • Assembly length
    Hose length plays a crucial role as well, ensuring it doesn’t twist, knot, or break. To avoid these problems, Orientflex will ensure that your components are properly fitted to achieve the longest life of the hose.


When considering temperature factors, both environmental and internal product temperatures need attention. Extreme environmental temperatures, whether too high or too low, can shorten the hose’s lifespan. Product temperature significantly affects hose longevity; unsuitable temperatures can lead to cracking, hardening, or drying out. Different products have varying temperature impacts on hoses, so Orientflex recommends running it at the highest acceptable temperature for different products.

Before selecting the right hose, understanding your application is crucial. Factors considered vary depending on the application, highlighting the need for customized products to perfectly fit your needs. To confirm your requirements, you need to answer several questions:

  • How did the original hose perform?
  • What equipment does the hose come into contact with?
  • What environmental factors surround the hose?
  • Are hazardous chemicals present near the hose?
  • Does the application assembly include mechanical loads?
  • Are there restrictions in the transport route?
  • Are hose connections permanent or removable?
  • Will components experience wear and tear?
  • Are there regulations specifying which hose to use?
    Choosing the right hose involves considering numerous factors; the best way is to visit the application site for inspection and testing to ensure the provided product meets your exact needs.


What products will the hose be transporting? The nature of the transported product can significantly impact hose selection. Compatibility between the transported product and the hose is crucial. Internal hoses, external coatings, hose end fittings, and connection parts must all be compatible with the product being transported. Chemical compatibility is essential to avoid issues; please refer to the Orientflex product compatibility chart.


When recommending hoses for your application, we confirm the maximum operating pressure and vacuum pressure that your system or equipment can withstand. Determining the maximum operating pressure of the equipment, the frequency of pressure peaks, and whether the transported product affects the pressure are crucial when choosing hoses. Additionally, consider whether your equipment’s required pressure aligns with the hose’s needs.


Selecting the right fittings, type, style, material, direction, and connection method ensures proper connections, prevents leaks, and improves installation and operability. At Orientflex, we offer a variety of fittings, including custom fittings, standard fittings, molded fixtures, etc. We use the SZR system for crimping to ensure no gaps.
