Sanitary Flange Quick Disconnect Couplings for Flexible Fluid Connections

Sanitary flange quick disconnect couplings enable fluid lines with flange connections to be connected and disconnected quickly. They are useful in systems where line connections need to be disconnected and re-established flexibly. Our range includes different series, materials and designs, allowing you to select couplings to suit the installation situation and application requirements.

Materials and Coupling Series

The available couplings are offered in different materials:

Natural Kynar (NK7)
Non-animal-derived polypropylene (PP)
Polysulfone (PPSU)

The Large, Medium and Small series are available to suit different requirements. Material selection should take into account the medium being used as well as temperature and pressure conditions. Please check the technical specifications of the individual design to ensure it is suitable for your application.

Male and Female Designs

Male and female couplings are available for different connection configurations. Depending on the design, the couplings can be selected with open flow or an integrated shut-off valve. A shut-off valve can interrupt the flow of media when the connection is disconnected. The appropriate version depends on the system layout and the requirements for handling the medium.

Flange Connections in Two Sizes

The sanitary flange quick disconnect couplings are available for the following connection sizes:

3/4"
1 1/2"

When selecting a coupling, make sure the connection size matches the existing line and the intended installation. Compatibility with the other system components should also be checked.

Selecting Suitable O-Rings and Spring Materials

Sealing and spring materials are additional important criteria when selecting the right coupling. Depending on the design, O-rings are available in the following materials:

Viton
Buna-N
EPDM
Silicone
Silicone without lubricant

Spring options include 302 stainless steel and non-metallic designs. The appropriate combination depends, among other factors, on media compatibility, temperature, pressure and specific sealing requirements. If lubricants should be avoided or metallic components are undesirable, the corresponding versions can be considered.

Finding the Right Sanitary Flange Quick Disconnect Coupling

Key selection criteria include the required coupling series, male or female design, desired flow function and appropriate flange size. The materials used for the coupling body, O-rings and springs should also be matched to the operating conditions.

Our sanitary flange quick disconnect couplings offer various configuration options for fluid lines with flange connections. Use the available selection criteria to find a suitable version for your system.
