VIEGA equal tee connector FKM 18 mm – plumbing pipe fitting

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.
