Unidelta reducing T-piece PE to female thread 20 mm x 1/2" x 20 mm (603620)

Unidelta reducing T-piece PE to female thread 20 mm x 1/2" x 20 mm is a polyethylene branch fitting designed to join two 20 mm PE pipes while providing a 1/2" female threaded outlet. Intended for potable water and general plumbing systems, the fitting allows a threaded connection for valves, taps or accessories without the need for additional adapters. The component is suitable for creating a reliable branch connection or extending an existing PE pipeline in residential and light commercial installations.

Advantages

The fitting combines chemically resistant polyethylene construction with a standard 1/2" female threaded branch, enabling direct attachment of threaded fittings. Its reducing T design allows seamless transition between continuous PE runs and a threaded outlet, reducing the number of joints required. The component is lightweight and corrosion-resistant, suitable for underground or above-ground installation where compatibility with PE pipe systems is required.

Suitable for

• Branch connections in potable water distribution systems
• Connecting valves, taps or pressure gauges via 1/2" female thread
• Extending or modifying 20 mm PE pipeline layouts
• Residential and light commercial plumbing installations

Key specifications

• Material: polyethylene (PE)
• Connection types: 20 mm push-fit/PE run to 1/2" female threaded branch
• Pipe size compatibility: 20 mm PE on two ends
• Thread size: 1/2" female (BSP-compatible thread form for standard fittings)
• Application: potable water and general plumbing systems

How to use

Prepare the PE pipes by cutting squarely and removing any burrs. Insert the 20 mm PE pipes into the respective ends according to the manufacturer's recommendations for insertion depth, ensuring a secure fit. Use appropriate sealing tape or sealant on the 1/2" male threaded fitting before attaching to the female branch to ensure a watertight connection. Verify alignment and tighten fittings to a firm, hand- or wrench-tight position as recommended for the specific mating component. After installation, pressurize and check the system for leaks before commissioning.

Usage recommendations

Use only compatible PE pipe and compatible threaded fittings. Follow local plumbing codes and installation guidelines for potable water systems. For buried installations, protect the fitting from mechanical damage and ensure adequate bedding. If uncertain about torque or compatibility, consult technical documentation or a qualified installer.
