EF Tapping Tee - Live Branch Connection Without Cutting the Main

The EF tapping tee is a core branch connection component for municipal water supply and drainage, gas transportation and industrial fluid systems. It is made from high-quality PE100 raw material and carries integrated heating elements and combined cutting blades. Its core advantage is the ability to make a branch connection while the main stays under pressure, without cutting the pipe: electrofusion fuses the fitting to the main pipe to give a leak-free seal with a strong interface.

Key Features

• Live tapping - the branch is created under pressure, so there is no need to cut the main pipe or shut the line down.
• Leak-free, strong interface - electrofusion fuses fitting and main into one continuous structure.
• Compact installation - no heavy equipment is needed, so it can be installed even in narrow spaces.
• Durability - corrosion resistant and anti-ageing, with a lifespan of up to 50 years.

Specifications

• Material: PE100
• Size range: DN20 - DN315
