Unidelta PE pipe tee 20 mm 603020 for polyethylene plumbing connections

The Unidelta PE pipe tee 20 mm 603020 for polyethylene plumbing connections is a three-way polyethylene fitting designed to create a branch from a 20 mm plastic pressure or non-pressure line. Intended for use in potable water systems, irrigation and general plumbing, the tee provides a corrosion-resistant junction that maintains flow continuity while allowing a secure lateral connection. Its design supports durable joins in low- to medium-pressure networks where PE fittings are specified.

Advantages

This polyethylene tee delivers reliable, long-lasting performance thanks to the material’s chemical inertness and resistance to corrosion. The fitting is lightweight and easy to handle during installation, and its smooth internal surface reduces flow resistance and helps prevent buildup. Compatible with standard 20 mm PE piping, the tee supports leak-free connections when used with appropriate joining methods and ensures stable service in common plumbing and irrigation applications.

Suitable for

• Branching potable water distribution lines in residential or commercial systems
• Irrigation networks and garden watering systems
• Low- to medium-pressure fluid transport in PE piping installations
• Temporary or permanent plumbing connections in outdoor or underground runs

Key specifications

• Material: polyethylene (PE)
• Nominal branch size: 20 mm
• Configuration: three-way tee for creating a lateral connection
• Typical applications: potable water, irrigation, general plumbing
• Pressure rating: suitable for low- to medium-pressure networks (verify system requirements before installation)
• Corrosion resistance: inherent to PE material

How to use

Select a compatible 20 mm PE pipe and prepare the pipe ends according to the chosen joining method (electrofusion, butt fusion, mechanical compression or other approved technique). Ensure pipes are clean, cut squarely and free from burrs. Position the tee and complete the connection following the manufacturer’s or installer’s procedure for the selected joining method, observing correct alignment and cooling or curing times where applicable. After joining, verify the integrity of the connection by pressure testing the section in line with local codes and standards.

Usage recommendations

Confirm that the tee’s pressure class and joining method match the requirements of your system. Store fittings away from direct sunlight for extended periods and protect from sharp objects that could damage the material. For buried installations, ensure adequate bedding and mechanical protection. When in doubt, consult a qualified plumber or installer to select the correct PE joining technique and to perform pressure testing after installation.
