VIEGA equal tee FKM 22 mm plumbing fitting 628451

VIEGA equal tee FKM 22 mm plumbing fitting 628451 is a three-way connector designed to join three pipes of identical 22 mm diameter while providing a resilient FKM sealing element. The fitting is intended for installation in potable water, heating and general plumbing systems where a uniform bore and reliable elastomeric seal are required. Its design focuses on leak-tight connections and compatibility with standard 22 mm pipes used in residential and commercial installations.

Advantages

The VIEGA equal tee features an FKM (fluoroelastomer) seal, offering chemical and temperature resistance compared with standard elastomers, which helps maintain tight joints over time. Its equal-bore design ensures consistent flow characteristics through the branch and main runs. The 22 mm diameter matches common copper, plastic or composite pipework sizes, simplifying integration into existing systems. The fitting is manufactured to industry-aligned tolerances for dependable mating with corresponding press or push-fit systems compatible with VIEGA components.

Suitable for

• Potable water distribution in residential and commercial buildings
• Domestic heating circuits and radiator connections
• General plumbing branches where a three-way equal-size junction is required

Key specifications

• Connection diameter: 22 mm (all three outlets)
• Seal material: FKM (fluoroelastomer) for enhanced chemical and temperature resistance
• Type: equal tee (three-way branch with equal bore)
• Application: potable water, heating and general plumbing installations
• Material compatibility: suitable for use with common 22 mm copper, plastic and composite pipes (subject to system compatibility)

How to use

Prepare pipe ends according to the installation method specified by the chosen joining system (press, push-fit or other compatible method). Ensure pipe ends are clean, free of burrs and cut squarely to guarantee proper seating against the FKM seal. Insert pipes fully into the fitting until they reach the stop or follow the marking for insertion depth. Complete the joint using the appropriate tool or method for the system in use, and verify each connection for correct engagement. After installation, perform system pressure and leak tests in line with applicable standards and local regulations.

Usage recommendations

Use this equal tee in systems that require compatibility with FKM seals and a 22 mm bore. Verify chemical compatibility and temperature limits of FKM for the fluids and operating conditions in your installation. Follow manufacturer instructions for the chosen joining technique and carry out pressure testing after installation to confirm leak-tight performance.
