## Summary description

VIEGA equal tee connector with FKM sealing, 18 mm nominal diameter (MPN 628437). A plumbing pipe fitting designed to create a T-branch in pipelines while maintaining leak-resistant FKM elastomer sealing. Suitable for use with compatible 18 mm pipe systems in water and engineering installations where chemical and temperature resistance of FKM is required. Used for branching supply lines and connecting fixtures.

## Long description

The VIEGA equal tee connector FKM 18 mm is a plumbing pipe fitting designed to create a T-branch in compatible 18 mm pipe systems. It features an FKM elastomer sealing element that provides enhanced resistance to heat and many chemicals compared with standard rubber seals. The fitting is intended for use in water and engineering installations where a reliable, leak-resistant branch connection is required and compatibility with FKM is preferred.
Advantages
The FKM sealing material offers improved chemical and temperature resistance, contributing to long-term sealing performance in demanding environments. The equal tee design provides a uniform branch without changing pipe diameter, allowing straightforward integration into existing 18 mm distribution lines. Constructed for compatibility with standard 18 mm plumbing systems, the connector supports secure mechanical joining and a compact footprint suitable for confined installation spaces.
Suitable for
Branching potable water supply lines within 18 mm pipe systems
Connection of fixtures and appliances in domestic and commercial installations
Systems requiring enhanced chemical or heat resistance in seals
Renovation work where a T-branch must match existing 18 mm pipe dimensions
Key specifications
Nominal diameter: 18 mm
Fitting type: equal tee (T-branch)
Sealing material: FKM elastomer
Application: plumbing and engineering installations for water and compatible fluids
Design: compact, equal-diameter branch for uniform flow
How to use
Prepare the 18 mm pipes by cutting squarely and deburring the ends before assembly. Ensure the FKM seal and connector surfaces are clean and free of debris. Insert the pipes into each port of the equal tee until they reach the designed stop, following the joining method recommended for the pipe system in use (push-fit, press-fit, or compatible mechanical joining). After assembly, perform a pressure or leak test according to applicable installation standards to verify the integrity of all connections.
Usage recommendations
Choose FKM-sealed fittings where higher temperature ranges or chemical exposure are expected; verify chemical compatibility of FKM with the fluids in the system. Follow local plumbing codes and manufacturer guidelines for installation torque, joining techniques, and pressure testing to ensure reliable, long-term operation.
