OUR CONNECTOR/FITTING SELECTION GUIDE
Simplify your product research by following our guide to how to select the most suitable industrial connector/fitting for your requirements :
Connectors/fittings are essential elements for connecting your fluid processes, assembling your pipe systems as well as for building industrial machines.
The functionality and assembly that you require are both important considerations for choosing the most suitable product.
This is why we have written this guide to help you to select the most suitable Béné Inox connector/fitting for your installation.
You should take the following points into account :
1. The application environment
First off all, you need to establish which standards are linked to your process :
- Industrial (standards linked to chemical, water treatment, construction industry sectors etc.)
- Food and Beverage industry (CE1935/FDA)
- Pharmaceutical and biotechnology (USP class VI / ASME BPE)
It is also important to note that: you will need to consider similar points when you are choosing the piping that you will use with your connectors/fittings.

2. Usage conditions and requirements
You need to take into account several factors to make sure you choose the right connector :
- Step 1 : Temperature & Pressure
These two parameters are crucial for defining the fluid that will be transported in your process.
If you do not consider these parameters correctly, there is a risk that your connector could become damaged and this damage could cause a leak.
Here are the different indicators that you should take into account :
o PN : nominal pressure (working pressure or operating pressure at 20°C)
o MAP : maximum allowed pressure (or pressure at which sealing will fail, first leak pressure). Please, read our specific document about this subject : MAP
Warning: temperature also plays a crucial role in the choice of the most suitable gasket to use with your connector/fitting.
- Step 2: Flow rate for determining internal piping diameter (cross-section)
Recommended flow velocity is specific to each fluid type.
For example, for water, 2-3 m/s is recommended in a piping system to make sure that its flow is not too turbulent.
Once you have defined the flow rate, you can establish the relationship between fluid velocity and cross-section, so that you can calculate the piping diameter DN :
- Step 3: Fluid type
You will need to consider the type of fluid which will be transported through your connector/fitting so that you can check it is compatible with the materials used in your connectors and their gaskets.
In most cases, you should choose a 304 stainless steel connector for use in quite mild environments and a 316 stainless steel connector for use in more aggressive environments.
A connector's gasket plays a very important role in making sure that your process remains sealed/watertight. If a gasket falls apart, it could pollute the transported fluid and also cause the process to leak.
Due to this, material choice is extremely important. This is why it is necessary to check material chemical compatibility.

You can also find information about the certification of our gaskets directly on our product information sheets.
- Step 4: Connection types
Connections can be made by welding fitting/connector ends (either by Butt Welding or Socket Welding), by screw assembly, by clamping (with flanges or clamp collars) or by press fitting.
It is also important to note that: you will need to consider all applicable standards as well as your future process maintenance requirements when you are choosing your connector/fitting type!
