## Long description

The VIEGA Mufa dwuprzelotowa FKM 22 mm coupling, model 628963 is a 22 mm through coupling designed for joining and repairing compatible tubes in plumbing systems. It features a fluoroelastomer (FKM) sealing element that provides resistance to a wide range of chemicals and elevated temperatures, making it suitable for applications where standard elastomers may not perform. The coupling is intended for use with potable water systems as well as industrial installations that require FKM-compatible sealing.
Advantages
The FKM sealing material offers enhanced chemical and temperature resistance compared with conventional rubber seals, ensuring longer service life in aggressive media and hotter environments. The through coupling design delivers a compact, direct connection that simplifies straight pipe joining and repair tasks. Manufactured by VIEGA, the product is produced to industry standards for dimensional accuracy and reliable sealing performance when installed according to specifications.
Suitable for
 Joining 22 mm pipes in potable water systems
 Repairing straight sections of compatible tubing
 Industrial fluid systems with chemical exposure
 Applications requiring higher temperature resistance than standard elastomers
Key specifications
 Connection type: through coupling for straight pipe joining
 Nominal dimension: 22 mm
 Seal material: FKM (fluoroelastomer) for chemical and temperature resistance
 Intended media: potable water and compatible industrial fluids
 Application environment: suitable for elevated temperatures and chemically aggressive media where FKM compatibility is required
How to use
Ensure the pipes to be joined are clean, cut squarely and free of burrs or deformation. Verify that the pipe material and dimensions match the coupling’s nominal size and that FKM is compatible with the media. Insert each pipe end fully into the coupling until it reaches the internal stop, maintaining axial alignment. Follow any installation torque or support requirements specified by the system design and ensure any retaining or locking steps required by the specific coupling variant are completed. After installation, conduct a pressure and leak test appropriate for the system and media.
Usage recommendations
Confirm chemical compatibility of FKM with the fluids handled in the system before installation. For potable water applications, follow local regulations for materials in contact with drinking water. When used in high-temperature or aggressive environments, schedule periodic inspections to verify sealing integrity and replace the coupling if signs of wear or degradation are detected.
